Current post: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 50 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

You may click on the PayPal Buy It Now link below. For accessories, please send money via PayPal or send me a private message for the total price. Thanks!

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 50 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

Revision 34: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Revision 32: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 50 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

Revision 30: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 45 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

You may click on the PayPal Buy It Now link below. For accessories, please send money via PayPal or send me a private message for the total price. Thanks!

You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 45 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

Revision 27: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

Revision 25: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 45 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on.

Revision 23: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 40 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

You may click on the PayPal Buy It Now link below. For accessories, please send money via PayPal or send me a private message for the total price. Thanks!

If you are not satisfy with the results or if it is too fast for you, you may send it back to me within 30 days in an unmodified condition.

Update: August 22nd, 2013 > I can adjust the controller for 24V, 33V, 36V, 48V, 60V, 66V, 72V, 84V, and other battery settings upon request.

It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Revision 20: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do.

Revision 18: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 40 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

You may click on the PayPal Buy It Now link below. For accessories, please send money via PayPal or send me a private message for the total price. Thanks!

If you are not satisfy with the results or if it is too fast for you, you may send it back to me within 30 days in an unmodified condition.

Update: June 8th, 2013 > I can adjust the controller for 24V, 33V, 36V, 48V, 60V, 66V, 72V, 84V, and other battery settings upon request.

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do.

Revision 15: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do.

Revision 13: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 35 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

You may click on the PayPal Buy It Now link below. For accessories, please send money via PayPal or send me a private message for the total price. Thanks!

If you are not satisfy with the results or if it is too fast for you, you may send it back to me within 30 days in an unmodified condition.

Update: March 29th, 2013 > I can adjust the controller for 24V, 33V, 36V, 48V, 60V, 66V, 72V, 84V, and other battery settings upon request.

More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:

72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v

Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 35 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

Revision 10: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now.

Revision 8: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 34 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

Revision 6: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 33 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

You may click on the PayPal Buy It Now link below. For accessories, please send money via PayPal or send me a private message for the total price. Thanks!

If you are not satisfy with the results or if it is too fast for you, you may send it back to me within 30 days in an unmodified condition.

Update: January 15th, 2013 > I can adjust the controller for 24V, 33V, 36V, 48V, 60V, 66V, 72V, 84V, and other battery settings upon request.

Revision 3: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:

Revision 1: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

Postby Lyen » Tue Mar 16, 2010 6:16 pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index.jsp?productId=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/1021134-mosfet-n-ch-100v-140a-220ab-irfb4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/262853773-209597704/Large_electrolytic_capacitor_CD293_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 30 made since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:

$89 USD free ground shipping in the United States & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

You may click on the PayPal Buy It Now link below. For accessories, please send money via PayPal or send me a private message for the total price. Thanks!

If you are not satisfy with the results or if it is too fast for you, you may send it back to me within 30 days in an unmodified condition.

Update: June 16 st 2012 > I can adjust the controller for 24V, 33V, 36V, 48V, 60V, 66V, 72V, 84V, and other battery settings upon request.
