Bosch PowerPack eBike batteries
(Redirected from Bosh PowerPack eBike batteries)Jump to navigation Jump to search
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 then reconnected in the right order (to be verified). The right order can be found here.
Known problems[edit | edit source]
Battery pack "dead", no power output, no indicator LED, no charging
