I think if you went for a comparison chart that showed pounds of battery per amp/hour you'd find that 6v golf cart batteries have the advantage. If I added up 4 100ah 12v batteries vs 4 235ah 6v batteries you'll be ahead with the 6's and also use less space and right at the same weight.
And if you have 4 125 amp-hour 12 volt batteries the end result would be more amp-hours than the 6 volt format. Or if there is room for an odd number of batteries, 12 volt may have the edge.
The best battery bank would consist of 2 volt cells--say 1000 amp-hours each connected in series to yield 12 volts. on my beer budget, I can't afford them.
