I'm going to install the Orion XS 12/12-50A DC-DC charger. I have a 2022 F350 and I have already installed 4 gauge +/- wire from the battery to an Anderson connector in the bed of the truck. I currently have Lead Acid batteries in a 5th wheel but when I upgrade to LiFePo4 batteries and start using the DC-DC charger do I need to disable the charging through the 7 Pin connector from the truck? If I don't will there somehow be current fed back to the truck or cause any other issues?
