Hi guys - I have an Ebike powered by a 36V bafang cr s104.250.sn

was working great for over 2 years but has now developed an issue

when you power it on the battery and power indicators light up as normal but after 10 seconds the power indicator drops to 0 and flashes - the bike produces no power and the buttons to turn up the power don’t respond once it hits 0

I have tested the battery and it seems fine holding stable at 42V fully charged (I’ve replaced cells in previous e bikes so it doesn’t seem to me as a dead cell anyway)

anyone have any ideas what would cause this ?
I assume it’s either going to be battery/controller/motor or a sensor issue

any help would be much appreciated
regards
Ben
