Hi everyone,
I have tried to google my issue but I haven't found anything relevant.
I have a 72V lithium ion battery (with BMS) on a custom build ebike, I was riding it this afternoon and at some point the motor stopped spining for no apparent reasons (the battery was arround 30-40% not sure of the exact voltage or percentage). I have checked all the connections and everything seemed to find. Then I have decided to measure its voltage, and instead of showing a 60~70V I had this weird 3.2 V showing up. I thought it was the bms that had turned of the battery for low voltage protection so I put in charge. After few hours, the battery was still "off" and the controller or battery gauge wouldn't boot.
There is no on/off switch on this battery pack, there is only one for the ESC.
I am not an expert with batteries as you can imagine , do you guys have any suggestion on the issue it might be ?
thanks in advance.
