Yes Dave 2 six volt golf cart batteries will out perform by a factor of 3 2 12 volt deep cycle batteries. We have a region meeting, this week ... I cant remember if it is in Moses Lake at my store or if it is next month! I carry a lot of these batteries in stock and at a good price to PNW4WDA members. I use a variant on my camper and can go for 11 days running the heater 24-7 and not recharge.
