I built a metal frame to hold a second AGM Group 31 battery under the floor of my Lance camper and I would have had more capacity with a single lithium phosphate battery and had a much simple installation. Lithionics makes a 125HA battery for 25% more charge capacity than a 100AH from Battle Born and others.
What is not understood or appreciated that instead of getting 80-90 percent of 125AH versus 50% of 100AH with a lead acid battery, the lithium phosphate batteries will recharge 4 times as fast as the lead acid ones.
With my current RV the two Lithionics 125AH can be at 50% SOC and brought back to 100% SOC in an hour with the Onan generator running versus 3-4 hours with the lead acid batteries at the same SOC level.
Saying one does not need lithium phosphate batteries makes as much sense as saying you do not need an air conditioner when you can always simply open the windows.
Going to a lithium phosphate battery is the single easiest and most beneficial upgrade to any RV one can make.
