Yup that is true you would have only 235ah in a two 6-sixer set up. But you'd only have 200ah in two-12er set up and they both have the same "safe draw down to 50%". The weight is about the same, the sixers being about 2 pounds heavier. The 12's will take up more space as their foot print is a little larger.

I found 2 batteries that compared closely for AH ratings. The first was a 6 v Duracell @235/2=117 and the second was an Apex 12 v with 115 AH. Two of each would be comparable. The weight for each was identical @ 68#. The 6 v took 794 cu in of space and the 12 v tool less at 729 cu in. The biggest difference is in height of the batteries. Typically 6 volt batteries are higher, in this case by almost 3". My battery box will not accommodate the extra height so for me there is no choice but to stick with a pair of 12v batteries. At least I found a pair totally 300 AH that will just fit.
