This 12V 5ah lithium battery is our smallest and lightest deep cycle battery. The RB5 is a lithium iron phosphate (LiFePO4) battery. It has twice the power, half the weight and lasts much longer than its lead-acid counterparts. It’s ideal for industrial applications where you need a long lifespan and quick charge capability or in outdoor/recreational use where lighter weight and capacity are key. It’s commonly used in the following applications: fish finder and flashers, robotics, scooters, solar lighting, remote power, security alarm systems, camping, hiking and other deep cycle applications.
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!
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.
