Wire size for battery bank
If you've got 4-6v Trojan t105 batteries wired for 12v with 2/0 wire between them would 2/0 be the proper size to run back to your converter/charger which is 12' away? And I guess the hot wire would n...

I ran 8 gauge from my 45 Amp Progressive Dynamics 8245 Battery charger to my battery bank. 10 feet worth. if you have an 8280, which is capable of 80 amps charging, yep, go larger. That's wiring going for recharging electricity going into the batteries.
If this if for running your inverter to convert 12 DC to 120 AC, you'll need to go way larger in wire gauge. 2/0 or bigger? Depends on the size of the inverter and the length of the run. Heavier gauge wiring needed when you have huge draws of current coming out of the battery. You can see this just on a normal positive terminal cable, narrow gauge wire off the alternator /voltage regulator on the positive terminal, and much, much heavier gauge wire going from the battery to the starter motor.
