BMS?

[Gagsinio]

Hi,changed the nylon gear in my BBSHD and battery stopped working. It's a Shark pack. Had the cells checked, all ok.Now I'll turn on, diplay comes on, one pedal revolution, it turns off. Turn the battery off an on, same thing happens. Could this be a BMS issue.Thanks in advance, G

I had this issue with a bad connection between the battery and the controller.

Hi, thanks for replying. Tried the battery on an identical bike, the same problem, so guessing it must be a battery issue.
