Troubleshoot house batteries dying while on 50 amp shore power. Diagnose converter, breakers, and connections to restore proper charging.
Freedom 20D losing one circuit after overload indicates internal breaker or output relay failure. Internal breakers may look fine but fail closed. Open unit to locate and test internal protection devices. Replacement parts available through Xantrex or specialty suppliers.
Protect alternator from lithium battery high current draw using DC-DC charger for current limiting or temperature-controlled relay. DC-DC charger is best solution. Direct connection without protection risks alternator failure.
A lithium battery manager relay protects lithium batteries from overcharging by disconnecting them from the alternator when not needed. Installation involves wiring the relay between your alternator/converter and battery bank with proper fusing and control circuits.
Keep boost switch wiring separate from DC-DC charger circuit. Add dedicated chassis battery charger or use DC-DC second output for trickle charging. Boost switch remains for emergency use.
