Adding the DC to DC Charge Controller
It looks like you will have to tip the circuit board out of the steel box the BCC is in to make those modifications John recommended, but there looks to be plenty of room to do so. One of the reasons I was going to try an alternator only solution was both simplicity and room. I fitted a Chins 200 Amp Hour Lithium Battery (Amazon) in the compartment to the left of the entryway door, mounting the 100 amp breaker, positive cable terminal, and shunt for my meter on a piece of plywood next to the battery. There wasn't a whole lot of room left over. I reinforced the compartment with a couple of pieces of angle iron hung on allthread from the coach floor (Brian from Tito's RV You tube channel does this in his install). Putting everything there made it more accessible an let me keep my cable runs short. Where did you put your charge controller and lithium battery(s) and manage the cable routing?
