what gauge wire between two batteries?
I'm adding a second AGM battery to my truck camper. It's going to be under the bench seat in the back on the other side from the 1st battery. So their distance will be about at least 10-12 feet fro...

Do be careful to connect the batteries up in a balanced fashion and to do your best to ensure that the two interconnecting cables are the same length and gauge. Wiring them to be balanced means having the positive connection to the camper's systems at one battery and the ground connection at the opposite battery, so that current to or from either battery will travel through exactly one of the two interconnecting leads before getting to the rest of the world.
The batteries are identical, 31 grp. Trojan AGM. But the distance from their leads to the rest of the world is obviously different, as they are 10feet apart. I'll be using 4 gauge welding cable.
I was planning on simply going from the + to + and - to - of one batter to the other.
I'll still do that, but since the original battery in the box, has the ground (I presume), are you suggesting I keep it's negative connection as the ground and use the positive of the new battery in the further box as the positive which will connect to the rest of the world?
Trying to clarify this before the install tomorrow.
Thanks
