12 volts to 6 volts; whats the benefit?
So we're replacing our coach batteries which are four 12 volts group 27 batteries. We've heard some say they can get a longer run time off of four golf cart batteries over same number of deep cell t...

The Math:
12 Volt Group 27 MARINE/deep cycle times 4 = 380 Amp Hours and perhaps 114 usable before damage sets in big time
4 SIX volt in series/parallel forming two BIG 12 volt batteries = 420 to 460 amp hours of which you can safely use 50% (210 to 230) that is twice the run time
And very likely it will cost you less as well. since six volt gives the best Bang for Buck.
They are taller though.
