Hello everyone,
This is my Electric dirt bike spec:
Controller: Sabvoton 72150
Motor: QS273 8000w Hub motor
Battery 20s19p 72v 60.8ah Panasonic cells 150amp peak
The Sabvoton 72150 motor controller recently stopped working...
Everything was working fine until the controller sometimes starting shut off on me when I pulled full throttle. I usually had to turn it on again after it shut off and it worked fine. I originally thought it was the low voltage cut-off getting triggered at full throttle but I lowered the voltage cut-off setting to 55V and it was still shutting off. I had the max current cut off to 100amp to be safe and phase current to 200amp. But all of a sudden it shut off on me at full throttle again and now it won't turn on. When I hook the motor controller up to the power supply the voltage drops to near 0. When I opened it up I didn't see anything visually damaged or burned inside the controller. Is there a way I could fix the motor controller or diagnose what the issue can be? Also, I have no idea why it kept shutting down on me at full throttle... Please help!
