What size cable betwee 6V batteries?
What size cable should I put between the 6v batteries on my rig? Meaning between the positive and the negative? Thanks,

All these wire gauge questions come to the same thing:
A. ampacity so you can do the amps at all
B. voltage drop so you can operate your equipment
Lots of people seem to read the ampacity tables to get the safe size of wire, and miss the point about such things as staying above the inverter alarm voltage, converter voltage as seen at the battery, and solar controller set points
Once you have the safe ampacity solved then the lesson learned is often to go bigger than that to address the voltage drop issue.
I use the stuff sold at the auto parts store.
Everyone here (I think) understands that upsizing wire is necessary for long runs.... I once used some really thick stuff for a 25' run, I forget the gauge, but it was thicker than my thumb. But for the short, wire pairing the sixes, I used the auto parts store stuff... 4 Gauge as I recall.
