House Battery Charge While Underway
Once again I come to the best wisdom source to be found. 07 Holiday Rambler, 4 6v house batts, Magnum controller, Magnum inverter 2012. Situation is, when we dry camp we run the gen for 2 hours...

OK It's called Full Charge:
About your battery spark: There are often a number of devices that cannot be turned off like smoke and propane detectors. The worst offender on my rig is the ME2012 as it has a idle current of 0.3A and this cannot be turned off. This is excessive of course but Magnum calls it a design tradeoff. Unfortunately it's one of about 5 "design tradeoffs" or problems as I think of them. Here's the math for a month of storage: 0.3x24x30 = 216AH or about 50% discharge of my batteries.
Because my rig is stored w/o power and under a roof so that the solar doesn't work I installed a battery cutoff switch on the negative post to resolve all of the unwanted loads.
Full Charge (Battery Saverâ„¢ mode): The fourth stage occurs after four hours in the Float Charging stage. The Full Charge stage is designed to keep batteries fully charged over long periods and prevent excessive loss of water in flooded batteries, or drying out of GEL/AGM batteries. In this stage, the charger is turned off and begins monitoring the battery voltage; if the battery voltage drops low (12.7 VDC or less), the charger automatically initiates another four hours in float charge.
