I acquired an ebike this morning and after some investigation, I have concluded the battery is stuffed.
It's a 10S battery - currently sitting at 38 odd volts.. Sounds like a good start but as soon as I introduce any sort of load the voltage drops down (like half) and then either the bike or my discharger/tester cuts out due to low voltage.
I have eliminated the BMS as the issue by connecting the battery directly to my discharger / tester and seeing the voltage drop when load applied. My guess is the cells are stuffed. I could build a pack from 18650's thou it would be good if I could source these cells and rebuild the pack.. Does anyone know where I could get these? (preferably Australia)
