18 x 4115 MOSFET 84-132V Real Highway Speed Controller $259

[Lyen]

If you have any hope of driving the latest motors in their full glory (by which I mean max'ed out potential) and at high native speed, I can’t overstate how important it is to have a powerful controller in your electric bike. For my purpose here, I would choose the 18 FET controller from using the latest IRFB4115 MOSFET.

Introducing the newly brewed 18 FET 84-132V Infineon Programmable Brushless Controllers with high voltage IRFB4115 MOSFETs (EC184115-LYEN EDITION)

This is for a new, never used high voltage controller for racing in mind. It is originally designed people who have the gut for going above 50mph or 80kph.

There are other reasons for utilize the controller below:
1. You want to give higher speed to your beefy and robust high torque low speed motors such as the Crystalyte 5306, 5305, 5304, 4011, 409, 408, BMC V2 Torque version, Nine Continent - 9C 2807, Golden Motor HBS36 series, etc.
2. You have hub motors 20” or smaller high torque wheels and need to find a way to boost significant speed
3. You have a hall sensors added RC motor (Turnigy & Astro in this case) but want to take the advantage of higher RPM or to improve the gear ratios for more torque and/or speed
4. You hate getting horned by cars behind you telling you to get out of their way
5. You think high voltage is cool
6. You want to horn cars in front of you telling them they are too slow
7. You want a high voltage high speed controller in a small enclosure/chassis
8. You want to win the Spooky Tooth Death Race and compete against gas engine cycles after all
9. You want to combine your two 48v battery packs in series together for the high speed experience at 96v
10. You want to combine your three 36v battery packs in series together for the even higher speed experience at 108v

Another unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra output lead/pin. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard that reads electrical pulses.

This version also uses lock washers to secure the MOSFET transistors 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 MOSFET transistors will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

By purchasing the controller, you understand the following:

1. Your electric bike may classify as a motorcycle class vehicle in most states
2. Riding at high speed may not be legal on public road without proper driver’s license and auto insurance.
3. Risk of high voltage shock with improper high voltage batteries handling
4. Safety wears is advised and may required in most states by law
5. Typical bicycle cantilever, rim, and even disc brakes may not have sufficient stopping power
6. Typical bicycle frames are not designed for high speed application
7. Motorcycle class/training course(s) is highly recommended to ride safely at high speed

Note: Do not use a regular Cycle Analyst due to high voltage will destroy the internal circuitry. You should use the controller with the CA-LS model only.

This is a top of the line controller that comes with all the bells and whistles that are typical needed for the racing application including the CA connector, regen enable/disable jumper, USB-TTL plug, USB-TTL programming adapter with a push to send button and connector. Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). A special LVC calculation formula will be provided via PM or email upon purchase.

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. 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 as soon as your piggy bank is filled up.

Ugh oh, my secret weapon is in the public domain now. Time for me to get out on the highway for a speed run. I've been working on the aero before even installing this baby. I figure aero is going to be pretty important at 80+mph.

Your a bad man Lyen

Thats a good price considering there's little other options available. I'm very tempted but I think it'd cost me alot more than $259 in the divorce settlement

[AmpEater]

Is that last one still available?

I'll take it

Dear all respective members and buyers,

I have recently noticed there is a couple of competitors who are bad mouthing the high voltage controllers I sell will fail. They are making false statement to lurk potential buyers toward them. I am usually peaceful and quiet until now due to unfair statement made by competitors. I will try not to mention their names to avoid starting fires here.

I have requested for proof of evidence on June 21st, 2010 and received no proof of evidence for the cause of failure as of today.

Update as of August 4th, 2010, the bad wording from that seller has been removed with the help of the forum moderators including Ypedal and other respective forum members. I really appreciate your help.

Your Truly,
Edward Lyen

[The Mighty Volt]

Anyways.....I bought this......I hope to mate it to a 120v A123 Battery.....we will soon find out what it is capable of!

[MadRhino]

Many thanks Lyen,

I just received my new controller, well packed and mint. It is incredibly small, for the juice it can feed. I can't wait to install it on my ride and experience the new power. If you don't hear from me anymore, I'll be stucked in the branches of a tree with my bike, somewhere in the mountain.

Hello Lyen,

is it possible to build up this powerfull controller (same specifications) as an sensorless controller? I'm planing a project with the new Crystalyte Phoenix II sensorless hubmotor (sensorless, halfweight 5000er series of the original Crystalite Phoenix hubmotor). For this motor is a sensorless controller required like crystalytes own sensorless controllers. But their contollers have max 72V 40A=2880W. I'm planing a high speed project. And your assembled controllers are, so far i know, the best on the market for high speed ebike applications. In this forum you selling also a sensorless controller with less power. So i hope you can provide a sensorless controller with this high power specifications. One more question.
What is the minimal capacity the batterypack should have to work with this controller + crystalyte Phoenix II ? Hope for a positive quick answer. Thanks.

Best regards.

I'd like to revive this thread. Anyone been running this controller near its limits? I'd like to know how hard to push mine without overdoing it. Right now I'm only at 103V hot, 65a peak (160 phase).

I ran the Lyen 24FET version which has the same 4115 MOSFETs in it at 148 volts one day with no obvious problems. Right now, I use it at 132v consistently.

[cassschr1]

lyen,public answers would be helpful,then we would not need to inconvience you

[itchynackers]

He just reminded me that mine was optimized for 103V regen operation (as I asked him to do). If I wanted to up the voltage, I'd need to adjust a resistor.

[Lyen]

Hi Cass,

You have multiple controllers purchased in several time frame with different revisions. It would be best for me to answer via PM to avoid confusions.

Just going to bump this with an awesome review. Got this from Lyen 1 day before the Grange race and unfortunately it came with a dud FET and didn't even make it one mile. Since Lyen and I decided to room together for the race he said he could fix it for me the night of the race if I brought it + some 4115 FETs with me. Just so happens I had four brand spanking new IRFB4115's sitting around the parts bin (don't all of us extreme ebike geeks?). We stayed up to 2AM but he swapped out the bad phase that had just one single bad FET that wasn't even visible with 3 new ones I got since we didn't trust that bank even though 2 tested out OK (now spares). Did a few late night parking lot test runs and all was good as new.

Lyen provided me with service that I myself try to provide, above and beyond what is required.

I've since gone to the extreme and modded this controller (post is in the tech section) some more and it now draws a continuous 60A from the battery without even getting warm, highest logged FET temp was a whopping 57C after a bunch of 0-40mph, hit regen abuse. Stock I don't feel it should be run over 45-50A (on the cycle analyst with a calibrated shunt) and definitely keep it to 30-32S lipo 126-134 V max so you have some head room left.

The freeway speed comment in his title is no joke either. My 9C 2806 in a 20" wheel pushes me to 56mph quite quickly and this is a low inductance low resistance motor. I would not try this same stunt on this motor in a bigger wheel though.

Edward Lyen,

Invoice Received and Invoice Paid!

I appreciated the fact that you have answered all my questions/emails.
Amazing customer service!

Thank you and Best Regards....

[Stielz]

Very impressive controller!

Anyone have figures of actual power output (at the wheel) achieved with this controller?

[pendragon8000]

Hi Lyen,

just droped this post
https://endless-sphere.com/forums/viewto ... 45#p690106

but i think the 4115 fets will be more relieable for 100v and then i have option for 125v(30s lipo)

are these still availiable? and do you think it would suit a ht3525 hub in 26" mtb

thanks
Pendragon8000

[pendragon8000]

Thanks for sending promptly after payment and testing with youtube video.

I'm really keen to try this out. should be a great build (eventually).

I'll most likely beef up tracks and pump 60amps.

[alsmith]

Does anyone have the shunt resistance value- it's for the cycle analyst RShunt setting. It doesn't seem to be the same as the 18 x 4110 FET controller.
