LOL...but you are the one telling everybody that to keep the bad battery in parallel from bringing the other one down is to operate them sequentially. Operating batteries sequentially is a big pain unless you hardly ever boondock.
Don't get your panties in such a bunch when someone disagrees with you.

I really appreciate all the info, I went with the 6v golf cart batteries. For me they seem like the best option for my camping style.

Please enlighten us how you manage your "sequential" discharge and charging of your batteries over a 4 day boondocking camping trip.

So..what happens when you run your heater during the night and need to switch from one to the other once the one battery gets down to 50% discharge? You really wake up, measure the voltage and switch the batteries?
Seriously? :h So simply switching from one battery to the other using the battery disconnect switch is too difficult for you? LOL indeed! :B

To repeat AGAIN :S - impossible if you run those 12 volt jugs sequentially.

You have the additional issue of switching them so that are both in parallel to charge them.

The difference in internal resistance between 2 6V in series and 2 12V in parallel is negligible assuming the overall capacity is the same.
It's as easy test to do. Take both types and put a constant load on them and measure what the voltage drops from a fully charged battery.
Therefore, not a reason to choose 12V over 6V batteries.
Prove it ... as I can clearly prove otherwise. 😉
As this article clearly proves 12 volt jug internal resistance IS considerable lower and therefore suffer less voltage drop under heavy inverter load than a similarly rated pair of 6 volt jugs. Hard to argue with facts. :Z

I did find that when I had my 2 6volt GC2 batteries, they DRANK water like there was a leak. Ran it down below the plates in 3 weeks before I noticed.....almost 1/2 gallon between the two.
Just for giggles, what 6V battery do you have?

When comparing two 6v or two 12v, there's really little difference if one happens to die. It will become obvious quicker if a 6v dies, but you will likely be just as stuck if a 12v dies, as it'll probably drain it's partner too.
