Our RB300 is a 12VDC 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.
Not all lithium batteries are created equal. 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.
RELiON lithium batteries provide more energy for high consumption than traditional lead-acid batteries.
They also offer ultra-fast charging and discharging, high efficiency and a longer cycle life – plus no maintenance!
Electric vehicles, marine, recreational vehicles and solar.
