Replaced two existing 12V 100Ah LiIon batteries with two Epoch 300Ah batteries, thereby tripling the storage capacity. For example, A/C can now run close to 6 hours, vs. prevous 2 hours, without shore power or running the engine.

Mods were fairly simple, requiring only sawing off handles on the Epoch, and purchasing 4x 9-Inch 2/0 AWG extension wire cables, as existing cables where not long enough. Tied down battery with tie-down straps, and wedged it in existing battery holder to avoid it moving.

Highly recommended DIY storage power upgrade!

I upgraded the old lead acid batteries to the Epoch 12V 300Ah LiFePO4 Battery in my Class "C" motor-home, it was an easy upgrade and I'm getting great performance. I just completed a 14 day trip in the Western United States with many nights of dry camping, heavy use of the the 12V refrigerator, heater, lights, charging phones, iPads, the water pump, etc. and even did something I would never do with the old batteries...I powered up the rice cooker and TVs. I had plenty of power to spare. The Epoch app is great for monitoring performance and percentage of power remaining. Great product, wish I had upgraded years ago.
