12v to 6v review?
Currently have 2-12v 7ear old batteries that appear to be getting weak. Am thinking of replacing with 2-6v GC batteries (or maybe 4). Anyone have experience or real world review of moving to t...

Thank you all for the feedback. We have 500 w solar, 2k gennie as backup and a 2k inverter and have dry camped indefinitely in the past. Our plan is to do more boondocking, and to be honest I just NEED to replace the 2-12v but as always thinking of ways to make it “better”. I agree with some here that MOST of these conversations are way more advanced than most users would care about, probably including myself.
I think either way, I’m going to ramp up the number of batteries to 4 and base the rest of the conversation on cost and ease of use.
To be honest, I have only ever touched the 2-12v batteries twice per year (take them out for winter, put them in for summer) and they have lasted 7 years now. But I also have a trimetric battery monitor so keep an eye on them that way I guess.
Given your experience with 12V , and with the dry camping, but seeming to have been satisfied with the 12V in the past, I'd say it is somewhat of a tossup.
Take a look at battery cost, and based on my experience doing lots of boondocking, and trying to rely on solar as much as possible with genny backup, the extra deep discharge capability of the 6V (easily go hundreds of cycles down to 50% SOC and even hundreds down to 25% SOC) we go with Four 6V. But last time I bought batteries cost wasn't much of an issue, and the Trojans are now going on 10 years use with probably 3 months camping/year.
But battery prices have REALLY gone up in the last few years.
