I over charged my battery back in my DIY VW bus EV conversion. I am running (5) tesla S batteries in series. I think the damage is only to one module. I have removed it. There are 10 (18650) batteries with blown fuse wire and testing very low volts. 5 of the 6 groups were reading 4.3x V. I bleed the power down to 3.9x volts on these. The remaining group reads .504V. Can this be fixed?
1.) If I am able to isolate and charge most of the 18650 cells with blown wires so they are very close to the adjacent 18650, can I just re establish the fuse wire?
2.) If a couple of the cells are truely bad can I just leave it. ( I am going to install a BMS in the near future)
3.) Does anybody know how the 18650 cells are split into the 6S. The divisions of the stamped SS plates are almost random. They don't add up to the 74P groups?
