6 volt vs 12 volt batteries for boondocking
Hi all, While waiting for our new 28' Stealth toy hauler we're trying to figure out the best batteries to get for when we're back in the hills camped off the grid. We ordered the optional 200 watt ...

Would not this discussion be more relevant if comparing the 3-cell vs a 24, 27, or 29? Scrubber batteries in RVs is presently "uncommon".
I have done it with various 6v, 12v, 12v AGMs, 12v scrubber T-1275s (which came from golf car usage in their former lives, so they are also "golf car batts"), and various combos of.
Yes, you get less voltage drop with 12s than with 6s, but the biggest diff to reduce voltage drop was to improve the wiring in my case. (Fatter, shorter wire and tighten those connections.)
My current set -up is two 6s and two T-1275s banked as two big 12s in parallel. Voltage drop with a 120 amp draw (microwave on MSW inverter) is 0.6 volts, which is way better than I ever got before I improved the wiring no matter if using 6s or 12s. Even when I had four 6s and the two T-1275s banked as three big 12s I got 0.7 volt drop doing that.
So wiring is almost everything in this game. You can't compare other folks' results with what you could get without also knowing their wiring set-ups.
