Hi guys (& gals), I'm a total newbie here, this is my first post! :-)
Don't have an RV per se, have a houseboat on a nice lake here in GA, but basically it's just a camper on the water.
Had 4 Lifeline 220Ah AGM batteries in my inverter system (a Magnum MS2812 purchased new in 2010), batts were due for a replacement this year (6 yrs old), decided to try Lithium. I know the the Magnum MS2812 is not designed for lithium batteries, but I've done a good bit of research on this & other RV...
