These are the cable size recommendations for installing the 25 and 40 amp Redarc chargers.
Just to get 4 AWG wires from the truck starting batteries, through a CB and ignition controlled solenoid, then under the crew cab and to the front wall of the pickup bed, I ordered 25 ft each of red and black fine stranded welding cable from TemCo. You’d be surprised how little of that cable was left over. The circuit length was just over 20 ft just to the plug at the front of the bed.
I had to order a little more cable to upgrade the wires in the camper umbilical cord to the battery. The total circuit length by the time I finished was just under 30 ft.
I don’t think you’ll be happy with the performance if you try to use the OEM circuit through the 7-way plug. You’ll either be blowing fuses or having an auto-reset CB constantly clicking off and on because it’s heating up.

I didn't word my post correctly. I meant how long to charge Li batteries with the standard 7 pin wiring?
I understand how a DC-DC charger is installed.
