which is better(ok I already know the 6v x 2 is) but just wondering what the numbers mean.

My current set up:
2 12 V batteries wired in parr. amp hours 115

other

2 6 V batteries/gold cart wired in series. what I dont know is what is labelled on them
220AH rate at 20 hours
min @ 25 amps:425

So the 12V batteries have a amp hour rating of 115, the golf cart a rating of 220 ?

is this a no contest between the 2 or??

Since 6 volt is half of 12, the battery will have twice the amps but the same total "power". That's an over simplification, but I think you get the idea.

Six volt batteries have three cells, so the cells can be larger with thicker plates than the same size 12 volt, which will have six cells. The thicker plates will allow discharging and recharging much better than the thin plate batteries, so that is why most of us use pairs of 6 volt batteries instead of a pair of 12 volt.
