What is the form factor of the complete unit? The battery box in my camper will accommodate a single group 31 battery, and I currently have a VMAX agm. When I replace it, I’m going to be looking for a lithium group 31 with the highest AH rating. The highest group 31 I know of currently is around 155AH with BMS.

With LFP no gassing you can carry them anywhere, so the TC battery box size is not a limitation. Routing the wires might be the only factor.

Big lesson in choosing a single 100AH battery that can run the inverter/microwave was you still need to run the furnace etc, so 100AH is just not enough for a weekend off grid.

You need two batteries, which means twice the already high cost if LFP (although reducing as noted) and a place to put them. Good thing is they can go anywhere, including inside where it is warm, so that leaves the cost.

Even better if you can roll your own for more AH at less cost---except drop ins would let you place each of two batts in different locations wired in parallel instead of all cells in one box. Depends on your RV layout what is possible and your budget.

Main thing is you are not stuck with the existing battery location.

I thought that 100 AHs of LI was equivalent roughly to 210 amp hrs of lead acid GC batteries because you only run the GC batteries down to 50% whereas you can run the LI down to 0. My my 2 6v GC batteries last me 7 days before they are at 50% SOC, everything being equal won't 100 AH LI do the same? Would the LI equivalent last any longer running down to 0 than the 2 6v GC batteries running down to 50%?
