Two 6v wired in series is essentially one BIG 12v battery, so your inverter won’t know the difference... Remember that when the voltage doubles from 6 to 12v, the amp hours are cut in half...Generally speaking, 6v GC’s (golf cart) have a deeper depth of discharge (DOD) than 12v automotive starting batteries, thus more ‘usable’ amp hour ...
Absolutely !True "deep discharge" 12V batteries are difficult to find and cost at lot of $$$. Costco or Sams has golf cart batteries (size GC2) for about $90 a piece.
