Hi, i have a electric scooter that will travel a short distance, about 400m and it will power off. I can power on but when i twist the throttle it will power off again. Also, when i fully charge the battery i can only ride a short distance and it will power off. But if i let the scooter rest for more than 8hrs i can travel about 400m. So what could have happened to my scooter?

I don't know what type of mosfet is used. Can you help me find out what type of transistor the ZB7250 controller uses from the FLJ SK2 2x4000W 72V scooter? Otherwise great video. I learned a lot.

Just like several fellow EVer's below (or above), I have a controller that tests good at the mosfet's but does not work. First one was a sabvoton 72v150a that worked for a couple months then suddenly stoped, replaced with yuyang king 120v150a, worked for 10-15 min on test bench then suddenly stopped, before i even got to test ride, i was giving just a little throttle, it was spinning nice and smooth, and slow as it should, then.....nothing... No smoke, No spark, No zap, No smell, No heat/warmth anywhere, while still on test bench. Dont have another $300 to spend on yet another controller just to blow it up potentially. Also FYI when the controllers stopped working the throttle stopped getting 5v at red supply side wire and bluetooth function stopped working also supplied by 5v. So it seems to be an issue with specifically the 5v circuits of the controller. Is there a 5v step down transformer or something similar within the controller that could be the culprit? Let me know if anymore information is needed. You seem the only one i can turn to for guidance. It sounds like I'm not the only one, looks like it could possibly be a common perdicument , what could it be? Thank you for all your helpful content.

Sometimes, but in this case I'm far more inclined to believe it was the (haphazard) "shunt mod" that was done to that cheapo Greentime ESC to fool it into pulling more than it's rated current, that ultimately led to the early failure of those 4 out of 5 mosfets on the blue phase.
