Lighter Installs Start Here At about 24 lbs, this lightweight lithium battery is easier to lift into an RV compartment, boat hatch, or portable power setup. Its compact 12.95 × 6.77 × 8.42-inch footprint gives you 100Ah of capacity without taking over your available storage space. Cold Charging Made Simple This heated lithium battery uses charger-activated self-heating to support safer charging in freezing conditions. When connected to a compatible lithium charger, the heating system activates if the internal temperature is below 32°F, stops at 41°F, and then allows normal charging to resume. Protection That Works Every Cycle A built-in 100A BMS helps this 12V 100Ah deep cycle lithium battery handle everyday charging and discharging with greater confidence. It protects against overcharging, over-discharging, over-current, short circuits, and extreme temperatures, including automatic discharge cutoff below -4°F. Cell balancing and 5,000+ cycles at 100% DOD support reliable long-term use.
