Replacing 12-volt batteries with 6-volt
Have you replaced two 12-volt batteries in parallel with two 6-volt batteries in series to improve ampere hours? Were the results satisfactory? Please elaborate. Was the rewiring difficult?

6V advantage
1) can take 500+ charge discharge cycles to under 50% (more like 25%) SOC
Disadvantage:
do NOT work well with high current loads, like even 1000W inverter. First ALL the current is coming from each battery vs 1/2 the current from each battery in a similar parallel 12V, Next, they have much higher internal resistance than a 12V which means more voltage drop
6V vs 12V IMHO really depends on YOUR application. If you only occasionally dry camp, or often use high inverter loads, then 12V may be a better alternative.
If you often dry camp, can keep your load down to 50A or less peak, 6V may be a better choice.
