I want to keep both the starter battery and lithium house batteries charged when the vehicle is stopped and the engine is off, with the Victron smart charger on and hooked to mains power, what is the best connection method for the Orion-Tr-DC-DC smart charger? There seem to be a few methods in the manual supplied. Will it keep the starter battery fully charged? I also have solar fitted going through the Victron MPPT charger.
