I don’t see any obvious burn marks on the battery pins. So what could actually be wrong? What do you recommend I do next? I show the problem in this video.
PS: My setup is a BBS02 with a UPP battery.
PS2: Sorry if this isn’t the right sub, but I’ve asked in other places and haven’t found any help. I really need to get this fixed because I rely on this bike to get to uni every day.
