RELiON BATTERY RB300 12V 300Ah LITHIUM DEEP CYCLE
RB300 - 12V 300Ah Lithium Deep Cycle Battery
Our RB300 is a 12V, 300Ah lithium deep cycle battery. This Group 8D lithium iron phosphate (LiFePO4) battery is ready to replace your heavy lead-acid battery bank in your sailboat, RV or solar energy system. It’s only 82 lbs for a true 300 Amp Hour lithium battery that provides 100% of its rated capacity. The RB300 gives you the flexibility to replace several small, heavier lead-acid batteries in a single high capacity unit.
LiFePO4 batteries are lighter, take less space and last longer. While the up-front cost is higher than Gel, AGM or Lead-Acid the overall cost of ownership is lower over time because they require no maintenance and they have up to 10x longer life.
The RB300 offers high, reliable performance in any climate or condition for RVs, campers, sailboats and battery-based solar systems.
All RELiON Batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS). The BMS ensures a long lifetime, safe handling – and high-accuracy State of Charge (SOC) calculations.
