Got an issue with my battery. It is a LifePO4 36v 20ah. Purchased last year and sat over the winter, Gave it a charge and it didn't take much to top it off. I went for a ride today not even a mile and it went dead on me. I looked at my volt meter and sure enough dead nothing. Rode home hooked it up to the charger and the charger started to cycle like it was getting full. Checked the output from the battery and it is 27.4v. When I check across the string I get 3.3, 6.8, 10.1, 13.9, 17.6, 21.2, 24.7, 28.2, 32.0, 35.5, 39.2, 42.8. So in my limited mind the battery is full and there is a problem with the output of the bms.
Now I am at a loss the part numbers on the bms have faded and I cant read them. How would I go about getting a replacement bms? Yes it is a China based battery. Only info I have is
36 v Lipo 36120 cells
12 cell
Capacity 20 amp hr
Charging voltage 45-46
Max continuous disch. 40 amps
Rated disch. amps 20
Disch. cutoff protection 60 amps
3c discharge rate
1c charge rate
I would really appreciate any input Jack
