Q G’day David,
I am currently charging my caravan battery (130Ah AGM) from the tow vehicle (2015 Colorado 7) via an Anderson plug and voltage sensitive relay. My question is, can this cause damage to the caravan battery by overcharging a fully charged battery as there is no management of the power input? Would I be better off running this through a DCDC charger and, if so, is this better placed within the car or
