Update 11/8/2016
Smartphone-BT functionality got some enhancements. It's is now possible to program the controllers without the need to do the power cycle. Simply stop in a safe place, take out a phone, change the parameters as you like, tap "Flash" and done. The bike is ready to go.


Update 10/28/2016

Now offering 15Fet controllers with all the same features of the bigger brother, 18Fet controller, just about 25% smaller and lower price.
This can be a great middle ground for builds that need a bit more power than available with 12Fet controllers but space is limited.

Good for up to 6kw (60A and 100v). $179 with free shipping within continental US.
All the same options, including Bluetooth smartphone programming are available.

Here are some pictures for size comparison. The 15Fet controller is in the middle.

Update 5/14/2016

Controller is now independently tested to be compatible with the following motors:

MXUS 3000, v1, 2, 3, Leaf Motor, Crown TC3080, QS 205, Crystalyte H35, H40, more to come (also see below motor-specific phase/halls mappings)
All reported to be operating quietly and smoothly.

Update 5/9/2016:

Now 120V option is available at the same price - it comes with original 4115Fets and 120V caps (can potentially be upgraded to 150v) if you would like even more volts.

Spec/feature highlights:

- Violently silent (or silently violent), quick response to the throttle, strong and smooth acceleration from a dead stop without drama;

- Small and light package for the power it packs, weight: 0.7Kg/1.5lbs, dimensions are 8 1/2 x 3 1/2 x 1 7/8 ''

- Based on proven Xie-Chang/Infineon controller platform (censored) that is great for further modifications/hacking but comes with a new MCU allowing all the standard set of Infineon controller features (cruise, 3/4speed selection, regen, PAS, settings, etc) plus a number of new configuration options with the programming software (see a screenshot below);

- 18 FETs, two voltage range options: genuine IRFB4110 low resistance 3.7 mOhms (up to 100v) or IRFB4115 and 120V capacitors (120v), up to 150v possible with upgraded caps;

- Battery amps are programmable up to 99A and phase amps up to 370A, voltage range 36-I00V or 36-120V. I am running it reliably at 80A/200A, 88v nominal (100.8v charged) which is more than enough to unleash the beast in my heavy 120lbs bike but those more adventurous can push it further with additional mods (thicker batt/phase wires, beefing up traces, larger caps, etc.);

- A wide range of regenerative brake strength settings: 200 units instead of 2 settings available in older Infineon controllers. This feature alone can be a deal breaker for some people that need to have finely adjusted regen;

- Soft start setting with configurable ramp-up (set via software);

- 130% over speed settings that allows even higher speeds;

- Flux/field weakening control that allows to further tweak motor for speed. Tested unloaded speed with 130% overspeed, 11kv motor in 17'' moto rim and 88v battery: 130 mph/209 kmh (see screenshot below).

- "Soft LVC" setting (adjustable individually for each of the three/four speeds) allows to limit the current and/or speed below the LVC rather than cutting it off altogether. I would imagine a scenario where this can be used as a way to manage the range anxiety, reducing the power output after the charge level drops below a certain level but still will help to make it to a destination;

- Separate current and speed setting for each speed position setting;

- Heatsink aluminum box with larger fins (compared to 18FET Infineons) helps better with heat dissipation;

- $199 with free shipping within continental US

- International priority shipping (6-10 business days, any destination) is $35, controller only, options that increase shipping volume and weight may incur additional shipping cost;

- International express shipping (3-5 business days, any destination) is $70, controller only, options that increase shipping volume and weight may incur additional shipping cost;

- PayPal accepted.


Options:

- Programming cable - $15 ( if not needed, controller voltage/current, other settings can be customized to the specs before shipping);

- Bluetooth programming - $45

- Cycle Analyst connector - $10

- Throttle (half-twist) - $15

- Alarm/GPS tracking system mated to this controller, pre-wired/plug-and-play (Sound alarm on vibration detection/power disconnect, SMS alerts, remote listening via phone, GPS tracking, remote arm/disarm/panic/motor lock, remote start and much more - details will follow) - $70

- Cycle Analyst version 3 Direct Plugin - $125 (this price if purchased with controller)

- Universal DC stepdown voltage converter for 12v accessories (input voltage 36-100v output 12v 10A), wired into controller and turned on/of with the switch key - $25

- Anything else you can think of - ask and chances are, it can be done.

Some history info (moved from the original posting):

I've been running 100v at 70A and above on my hub-motor bikes for quite some time and have used square wave controllers that generally worked fine with only one pet peeve: motor rumbling on hard start (something I like to do a lot) and vibration transferred to the frame. The noise became especially pronounced after I drilled holes in motors for additional cooling. At some point, it was even embarrassing to try to sell people on the virtues of ebiking with my bikes making these kinds of sounds like a gas moped.

So, I've been looking for a sinewave replacement that could handle 100v and higher currents but that meant the target price needed to go up by at least 30% for off-the-shelf products.

Finally, after some research and experimenting, I came up with a modded controller that can run at 100v and above 70A silently and still doesn't break the bank. My hi-power bikes are now noise and rattle free, no more vibration transferred to the frame, they launch smooth and strong like rockets only without the rattle drama. I am now offering this controller with mods and programming software at the price point that I think would be very attractive considering the number of features it packs.

Looks beast whose the manufacture? Also aren't you selling a CA on eBay?

[Powervelocity.com]

Yep, I have CA v3 for sale.
Like all Xie Chang controllers, these PCBs come from China, I use a few suppliers.

No cariable regen? It's just slightly cheaper than a kelly

[Powervelocity.com]

I've tried Kellys and I ditched them early on. Maybe need to give it another try. They are solid built and reliable controllers but, personally, feel a bit golf-cartish to me (just not my style
Another thing is that Kelly's ebike series is limited to 72v, well 84v at 2-3x the price of this controller. Again, not something I want to go back to after experiencing 100V. I've been actually very pleased with fixed regen, once you set it right. It's more intuitive on brake levers vs. another throttle for braking. And then the modding component - I can mod the hell out of this controller, not something I would want do with Kellys.

No cariable regen? It's just slightly cheaper than a kelly

[evolutiongts]

Is this true sinewave? because I tried a MXUS Sinewave controller and I was dissapointed, since it was just squarewave with a bit of sinewave in programming. Meaning, only during cruising does it switch to sinewave under acceleration I can still hear noise.

I have a Sabvoton sinewave controller and thats a true sinewave with current throttle, very smooth and silent.

Is this controller current throttle?

[Powervelocity.com]

It is very quiet/silent compared to anything I've used before (including Kellys) but I have to do some more scientific tests to determine the purity of the wave.

how is the throttle response? Is it torque / current throttle?

[Powervelocity.com]

I have never asked myself this question as I've always used the throttle through the CA. I connected it once directly for a test and it did feel like a current throttle. I'll double check and let you know.

[evolutiongts]

Let me know because I am interested in buying one for testing how many do you have?

[markz]

I am very interested in this controller.
I like the fact it can go to 96A battery amps and 370A phase amps with a voltage range of 36-I00V.
My Lyen one only went up to 65A for the same price as yours.


Plus you got the tracking too, is that alarm/tracking sent to your Android or iPhone so when you get the buzzzzzzz you grab da bat and do sum batting practice at 2am Thats some serious Texas style justice, I love it. Garage door open, gun loaded, hide in the corner and BAM, justice served. No charges. Grrrrreat!

I have a kelly 300A 72V and it's very silent, very smooth, powerful and with variable regen.

The variable regen allow me to use the right level of regen and not always max it out when I don't need. I just kept my front brake as variable regen is modular enough!

For now, I can't much wrong from kelly.... apart from its massive size but for the price I'm happy with that!

What is max continuous output and what is peak output power?

Kellys are good controllers, I've used their mini series and they worked wonders. It was pretty amazing to see how controller that small with 50A load was barely getting warm. I even kept it inside the frame bag together with the battery, it basically needed no cooling. I never got to try variable regen on it, as I went to 100V and at that point Kellys were a limiting factor (capped at 90V). Since then I used fixed regen on Chinese controllers and it worked generally well. I also have it only on the front brake lever, so, when when I barely touch it, I am getting only regen (good for modulating speed), I squeeze it all the way, I am getting regen (rear) and front braking. If I don't need regen, I simply engage the right lever (rear brakes). Worked well this way. I am thinking a variable regen done right would require a specially designed lever with built-in potentiometer. Using a thumb throttle for it can be fun but will be confusing for most regular/non-geeky riders (not fully initiated into ebiking )

[evolutiongts]

Any news on the throttle? Current or speed.

[Powervelocity.com]

What is max continuous output and what is peak output power?

This is modded controller with the modded software that allows to push the amps way above what the manufacturer envisioned.
I've replaced the original low quality MOSFETs with good original ones and beefed up the circuitry and wiring to allow for more amps.
80A at 100V top is where I am running it continuously, so that would make it 8kw of continuous output power provided that the controller is placed outside with lots of air circulation. The software currently allows to set it to 96A max (that would be 9,6kw peak power) but I would run it at that level only for quick jolts.

[Powervelocity.com]

Will get back on this one soon.

Any news on the throttle? Current or speed.

[drewjet]

How about efficiency compared to a regular controller?

[Powervelocity.com]

Efficiency would very much depend on how you chose to configure it and your riding style. Performance and efficiency are on the opposite sides of the scales - you get more performance at the expense of the efficiency and the other way around. If you launch it from stop (like I do), the efficiency will go to the drain. If you baby the throttle, the efficiency will go up as high as 2x or more. But just for the sake of the reference, I've been averaging 60wh/m on fake MOSFETs with this controller on a heavy 120lbs steel frame bike and 45 wh/m on lighter aluminum frame bike running on average 35mph on flat ground. I am yet to fully test and record the efficiency after MOSFET and other upgrades (lower resistance=less heat=more efficiency). Will update the thread once I have more solid data.

How about efficiency compared to a regular controller?

[Powervelocity.com]

I am working on it

Any chance on a 24fet version

[markz]

So many comments about Kelly controllers, this is the Xie-Chang controller which people like to call Infineon because it just stuck, someone saw an Infineon chip in it and called it that and the masses took hold of it. Like calling motors torque motors or speed motors, which is another myth described at length in another thread. I try my best not to conitnue the false info but I still call my controller the wrong term, others have too.

Anyways lots to choose from, I myself couldnt find no 24fet Xie-Chang. I will leave it there because the OP is working on it. BTW love the winks to elude to, well whatever.
