Battery Connector

[jimliston]

I am setting up my little green pea trailer for boondocking. It is a Trillium 1300 with the original converter. This is what I plan to do. I am leaving the original wiring alone. I'll have 12v lights as long as I am connected to the car. That is how the converter works. I am wiring in two 12 volt batteries which will be on the tongue and connected to both the converter and an inverter for the 110 stuff. The batteries are charged by the car alternator while in motion. Later, I will add adequate solar panels to recharge the batteries whilst a rest. There is an isolator between the car and the house (trailer) batteries. Here is the question: What kind of plug should I use to connect the house batteries to the car at the hitch? To clarify (maybe), I will have two connections at the hitch point; one to the Trillium converter cord which plugs into the seven-way socket on the bumper and a simple (?) weathertite plug to connect the house batteries to the isolator. Does this make any sense? I know I am over engineering this setup, but I don't want/need to replace the old converter and I can add two receptacles for the inverted power seperate from the 110 outlets served by the shore power cable. Geez, now even I am confused. Remember, the question is only about what kind of connector should I use.

You only need one connection and you already have it. The isolator connects to the 7-way socket which then connects to the house batteries. How you connect the batteries to the 7-way socket is another question.
