House batteries to use with large inverter
We're planning some camping where generator use is restricted, so I want to make sure my batteries will hold up between charges. We'll usually draw less than 25 amps, but I'd like the option of runni...

You can run the MW on a pair of 6s just fine, but there is a higher voltage sag under load than with 12s. This means that you need to be above about 75% SOC to keep loaded voltage above the 11v inverter alarm. To stay above 11v at 50% SOC you need four 6s. With solar it is easier to stay in the high SOCs, but with gen/charger and doing 50-90s it is more likely you will be below 75% when you want to run the MW.
However, guys here with AGMs (which are 12v) report small voltage drops under heavy load so they can be much lower in SOC and still run the MW with only two batts (sometimes with just one AGM) This makes them ideal for small RVs which can only carry two batts but still want to run the MW.
