The 12v interstates that I bought 5 years ago are on their last legs. As I contemplate their replacements I am wondering if any of you have any recommendations. I have been told over the years that 2 6volt golf cart type deep cycle batteries will outperform 2 12 volt deep cycle batts. I hear that they not only hold a charge longer but they charge faster and recover quicker. Anyone willing to share their thoughts and/or experiences on the matter. Thanks in advance ๐Ÿ™‚ ---

Both can operate the same 12 volt system. The two 6 volt batteries wired in series gives you 12 volts. The two 12 volt batteries need to be wired parallel to give you 12 volts. Hope I remembered that right and someone doesnโ€™t fry their electrical system with 24 volts if I reversed it ๐Ÿ˜†. ---

You are correct, as far as 6 volt goes, yea if you do a lot of dry camping, the 6 volt might have an advantage, but I would think you would need to run four of them, then it gets spendy. My fifth wheel only came with one 24 battery , after 4_1/2 years it finally gave up. Bought two 27โ€™s from Costco, and after the fact still wondering why, when for 4_1/2 years one 24 did me fine. Not all is lost just recently bought an electric motor for the pontoon, and will probably use one for that. ---

Hey Bear, I think this video will answer your question. Two sixes are in fact better than two twelves. ---

Thank you for all the useful input fellas. The video was especially insightful. I will be shopiping for a couple of 6volts this weekend. Guess I should start at Sams and Costco. Thanks again everyone.
