I have a motor boat with three lead battery packs. The generator charges today the starter battery and the house battery via a smart relay. The third battery in the bow is today not charged. The engine is VP from 2017.
I have bought an Orion Tr-smart charger 12-12 18A isolated to be able to charge the bow battery. I will change the bow battery to an AGM-type to avoid gasing. My question is where to connect the dc-dc charger, point A, B, C or D according to my wiring diagram.
