Batteries
I am going to buy new house batteries. I now have 2 12 volt batteries. Will I be better off putting back 2 6 volt batteries or 4 6volt batteries or just replacing what I have? I plan on doing a lot of...

Hi,
The real answer is "it depends".
For example, if a large inverter is in use, then 12 volt jars may work better.
Twin six volt jars are not always a higher number of amp-hours than twin 12 volt jars.
Look at amp-hour cost per year of operation.
Wiring in a balanced manner is important.
Solar has become so cheap it is almost a sin to not have at least 60 watts per 100 amp-hours of storage.
In short, battery bank design needs to "fit" the camping style.
Two 12v batteries in parallel do provide more instant amp draw (NOT necessarily CAPACITY) so I guess that would definitely be a major consideration if you have a massive inverter and only room for 2 batteries. Is the Amp drain level that small on 6v cells that the usual 2000-3000 Watt inverter would cause a problem?
some 12v cells do have high capacity but it is almost always cheaper to get a comparable amount of Ah capacity by going the 6v route.
I have no solar save a little 5W trickle maintainer panel built into my A/C shroud so... am I a sinner?
