RB300: This 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. This solar storage battery gives you the flexibility to replace several small, heavier lead-acid batteries in a single high capacity unit.

Features: RB300, 12V, 300Ah, LiFePO4 Deep Cycle Lithium Battery
- 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.
