Largest Lithium AMP Hour Battery - 2023 Arctic Fox 865

I am running three Redodo Mini 100 Ah batteries successfully in my Wolf Creek 840. They all fit in the original compartment. No complaints so far. Charging via the built-in converter which has a retro fitted upgrade to charge LiFePO4 batteries. These batteries cost me less than $350 each. I attached a disconnect to prevent any unwanted charge cycles.
