The RELiON RB200 is a 12V 200Ah Lithium deep cycle battery. This lithium ion phosphate LiFePO4 battery is ready to replace your heavy lead-acid battery bank in your sailboat, RV or solar energy system. It’s only 27.7 kg for a true 200 Amp Hour lithium replacement battery that provides 100% of it’s 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 10 times longer life.

The RB200 offers high, reliable performance in any climate or condition for RV’s, Campers, Live Aboard Boats, Electric Vehicles, Marine and 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.
