So you can’t just charge the battery off the 12v lead in the 7 pin connector? I was thinking about doing that but I haven’t even researched it yet.Here is the tank I used....

On DC-DC charger, 1) I needed a way to charge a different size and type of battery (100ah LiFePro) 2) I wanted a clean way to charge the trailer as we drove from point to point 3) leave it plugged in when we arrived into camp without having to think about unplugging it or turning off the lead to the trailer from the truck
