RB80 Lithium Battery

12V 80Ah Battery

This 12V 80 Ah lithium iron phosphate battery is a safer, more lightweight alternative to lead-acid in your marine, solar RV, or other deep cycle applications. At 25 lbs, this battery is less than half the weight of a lead-acid equivalent and is ideal for deep cycle applications where you need lots of power for a longer period of time. It maintains consistent power and is equipped with handles for carrying. Eighty Amp-hours of capacity means a full day of power for mid-sized trolling motors or for a long day on the road in your RV.

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 longer cycle life – plus no maintenance! 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.
