    Maximize 12FET controller performance

    I want to bring out maximum performance from my 12 FET controller. What would be the max. safe Phase/battery current? It is a EB212 controller with stock shunt(2 wires, aprox 2.5mOhm), fitted with (12) 4110 FETs. Battery and Phase traces have been beefed up considerably, battery wires are aprox...

    Hooked controller reversed - blown

    Had a melted battery connector that I was fixing. However, after the fix, I've hooked up my 206 Infineon controller to reversed polarity. I saw a big spark in my switch, and a short current burst heated up my connector. Now controller won't work and CA DP displays 56A no load. What could have...

    CA accuracy?

    I am using a CA 2.11 direct plug in and am wondering what is the accuracy on them. When I first plugged in to the controller, I saw battery voltage rising 1-2 volts in some 10s of seconds. It finally settled down close to what my cheapo multimeter displayed. This still happens usually, having a...

    Blown Puma gear - replaced

    Today I managed to blow one of the plastic planetary gears of my PUMA motor. I've bought it second from UK a year ago, have served me great, has more then 2000km on it. It was overpowered from the beginning. Most of the time I run it at 66v(18sLiM) 20a controller(70a phase), but 2 weeks ago was...

    twitchy throttle response problem

    I have a 12 FET Infineon controller from ecrazyman, this is probably the soft start version. And an ecrazyman hall effect thumb throttle. The throttle response is sometimes like intermittent. The throttle response is not linear, at the end the current rise is steeper. But the problem is, it...

    Hall throttle signal range limiting

    I am using a thumb throttle from Keywin (with 48v led indicator) with a 12FET infineon controller. However at around 90-95% WOT the power cuts, I am probably getting a too high hall signal. Has anyone experienced this problem? I think the hall signal is between 0.5-4.3v What mod is needed to...

    12 FET controller board not working after installing FETs

    Hi, I am fairly new to ebike & controllers, but decided to take the hard way and make myself the controller, because it can be fun. I ordered a 12 FET board from keywin and planning to populate with 4110 FETs. Also got the USB to Serial port cable for programming and a thumb throttle. This is...

    New guy wants to break into e-biking, recomandations needed

    Greetings everyone. My name is Zsolt. I'm 25 and live in Cluj Napoca, Romania(Europe) . And I love biking :) I was reading this, and some other forums finding out the new trends in biking, and I definitely want to give a try going electric. I've never seen one in my surroundings is not common at...
