RELiON RB200 Lifepo4 Lithium Ion Battery (12V / 200Ah / 6SC)

Part No: REL-RB200

RELiON RB200 Deep Cycle Lithium LiFePO4 Battery 12V 200Ah

RELiON 12V, 200Ah 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 weighs only 61 lbs for a true 200 Amp Hour lithium replacement battery that provides 100% of its rated capacity. The RB200 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 RB200 offers high, reliable performance in any climate or condition for RVs, campers, sailboats, catamarans, battery-based solar systems, and other deep cycle applications.

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.

Applications: Marine, Recreational Vehicles, Solar & Electric Vehicles
