MaxLi Battery is a Lithium Iron Phosphate (LFP or LiFePO4) battery designed for recreational vehicle (RV) and Marine deep cycle use,suited for use in off grid homes and cabins, industrial applications and more. Our "drop in" replacement for lead acid batteries is unlike any other on the market. The built in BMS system offers 8 different protection modes including, over and under voltage, over and under temperature, over current, short circuit and balance function. 


MaxLi Batteries are much lighter and charge fast, about 40% of the weight of a comparable lead acid battery. Delivers twice power of lead acid battery,even high discharge rate,while maintaining high energy capacity.Your RV or boat will likely have a compatible battery charger built in that is ready to use with MaxLi Batteries. Whether you are on the road, on the water or off the grid, MaxLi Battery offers a solution that outperforms the competition.
