Bosch PowerPack eBike batteries
This applies to various Bosch Powerpack eBike batteries having a BMS board that looks similar to the one shown.
Some are susceptible to water damage from ingress at screw holes, add glue there when reassembling. Apparently most of these BMS boards do not brick themselves when the battery cells are disconnected (to be verified).
Known problems[edit | edit source]
Battery pack "dead", no power output, no indicator LED, no charging
