I have this evolve system that have been exposed to water. The battery is dead and I have made a new one. Both the bms and the esc seem to have avoided the water. But that’s not certain.
When I plugged in the battery it nothing happened could not turn on the board or charge either.
The battery measure 34V (its not fully charged fully yet) before the bms. After the bms it measure 20V. So the bms is not completely dead something happens there.
How do I know if the bms is the problem?
Any suggestions in how to troubleshoot this and find the solution / part to change?
How do I know if the esc has taken damage. Any suggestions?
