I have 2000 Bounder 39z. We have been full-timing for 18 years, but now I "must" use a CPAP machine to sleep with some changes where necessary so I could boondock if I wanted to. I have six 6-volt deep-cycle interstate batteries. This time 4 are in the battery compartment and I added two on the other side of the coach. They run through a Xantrex RV2012 GS inverter and I have 3 125 watt solar pannels on the roof flat. I have a controller that will start the generator when batteries get to 11.5 volts, or wherever I want to set it and charge the batteries to absorb charge. This way I don't have to worry about the CPAP losing power during he night.
Now the question. The four batteries that came with the coach have I would guess "0" size wire, when I added the extra two batteries on the other side of the coach I used #2 wire to connect them together and to the primary positive post for all battery's. Does anybody see a problem using the #2 wire ? and if it is going to be a problem, how about if I run a second # 2 wire. I would think that two #2's would be the same as a "0" wire.
No matter how big the wire is, the connector on the ends are about the same size and should carry the same voltage.
