I have a xiaomi 42v charger it’s drop 14v , what i can check to start repairing?

My friend if this sensor for the speed , where is the 3 hall sensor ??

Motor with single hall sensor without board on it !!!

I use controller without lcd , i use throttle with sp pins , but my controller run very slow how i can speed it ?

Last one i think my problem with pas

This is another controller , everything good but also this one not running “the motor working very well with another controller “ , is there anything i miss to short like brake or something else

Thanks you I solved the problem with buy new bms and everything ok …

My friend I measured the three MOSFETS by multimeter i put red probe on B+ and black probe on MOSFET right pin 37v , middle pin 33.3v and left pin 36.4v and the fourth MOSFET right pin 33v middle pin 33.3v and left pin 19.5v .

10 cells have 3.7v

I measured the cells individually, all cells give me 3.7v

My battery give me on B+ and B- 37v , after bms give me 33v , i don’t know what i can check to resolve the problem

What is ES ??

Last picture i mark some pins anybody know what is it for ??

Yes … it’s working and I measured throttle voltage was 4.9 volts and signal from 0.8 to 4.2v

My friends until now i cant run my controller without a lcd , i short gnd with rx wire as this diagram but it still don’t work is there anything can i check it ???
