You were right guys it was my controller ! thanks for help I just received my new controller with LCD8H, it works perfectly good and I have a little more power. Just my speed display is wrong.. under the real speed

I have a small question to ask you, Is the verification of the friction in the electric wheel (by connecting all the possibilities of pairs yellow-green, green-blue, yellow-blue, ...) when the controller is disconnected means the certainty that the wheel is not damaged or other problems are...

Hi, I think I success to repair my controller because not error 09 when I turn on and no rolling in my wheel but another problems appears, when i turn the throttle, just a "tick" noise in the wheel, no power ! Code 09 appears only when I turn the throttle... I am not lucky ;( Thanks

Hello, I need to buy a new Mosfet for my Controller : DC MOTO, Voltage DC36/48V, Current 26+-1A, Booster 1:1, Speet: 1.1-4.2 V Dual Mode Originals are AL1FX SAMWIN SW062R08E8T (can't find a new one on the web) Bojack TO-220 seems good but I am not at all sure ! Could you advice me ? thanks...

Yes it's true ! Thank you guys :D

hello, Parabellum, you are right, I tested MOSFETs with a friend who have a multimeter and one is fried near the green wire phase (logical with the rolling on my wheel only when this wire is connected). All others MOSFETs are OK (same values on multimeter). I would like to thnak you for...

Yes, you probably right, strange that cut one shunt cause a shorted mofset... I Hope no damage in my wheel !! I order a new controller 1000 w 48 v with LCD 8 (with current limit parameter avaible if I need it). Better than cut the shunt..

parabellum, the battery is disconnected All cables disconected from the wheel = no resistance Blue, Green and yellew connected = resistance Blue and yellow connected = no resistance Blue and green connected = resistance Green and yellow connected = resistance The resistance problem...

Thanks for your answer larsb, cutting a shunt is supposed to reduce the current from my readings, weird that it did how much damage :confused: resistance on the wheel is present all the time (motor connected and disconnected) except when I opened my motor to check the magnets there was no...

Hello everyone, I am Valentine from France. I come to this forum to ask you for help because I think I may have damaged my e-bike. 1 month ago, I installed a 1000 watt 48 volts rear wheel and have a 48 volt 15 AH Samsung battery. Following problems with annoying micro cuts when I was driving...
