12V or 6V Batteries - Which charge Better?
I plan to switch to two 6V batteries in series, but before I do, I need to ask this question. When the batteries are drained and in need of charging, which will charge back up to full FASTER? Two ...

If both options have the same amp-hour capacity and assuming both are equally discharged, the difference in charge time should be insignificant. Running your engine should charge them much faster than your genny powered converter unless you've installed a converter with incredible output amperage. Don't forget that for best battery longevity, you don't want to discharge the battery bank beyond 50% of its amp-hour capacity. A Trimetric Battery Monitor is a good way to keep track of your battery charge or discharge. It's pretty hard to guess when the batteries are fully charged up without some kind of instrumentation.
