Which is the better battery configiration
I am trying to learn more about 6 volts batteries versus 12 volts. I know the 6 volts can be drained further and recharged more (better lifetime). At least that is what I think is true. But it seems...

One often forgot about fact is that the 12v are very much lighter than the 6 volts. I went from 8 six volts to three 12 volts (all AGM) and my total weight went down a bit over 300 lbs.
12v AGM battery weighs ~63lbs (google)
6v GC battery weights ~60lbs (google)
Two 12v AGM batteries (~100AH + ~100AH = ~200AH) weigh ~126lbs
Two 6v GC batteries (~210-220AH) weigh ~120lbs
Eight 6v GC batteries provides ~840AHs capacity and weighs ~480lbs.
Three 12v AGM batteries provide ~300AHs capacity and weighs ~189lbs.
Yes, your weight dropped ~300lbs, but your battery bank capacity dropped ~540AHs. Your weight didn't go down because you switched from 6v batteries to 12v AGMs, it went down because you cut your battery bank capacity down ~540AHs (which is certainly the right thing to do if you don't need that much battery bank).
