Was there a specific event that caused the circuit breaker to open? Is the lithium state of charge at 0% ?? When this happened? Or unknown. Lithiums do not like to be run down to 0% you get lucky and maybe get to take a charge a few times , but the ECM and or internal components will fail in doing this. Is there a possible short to frame or cause on the jack side? Circuit breakers open from a short. Not half way or otherwise. I'll check their website further on troubleshooting.
