This 12V 20Ah lithium battery is powerful yet compact enough to fit in many deep cycle applications. The RB20 is a lithium iron phosphate (LiFePO4) battery with more power, less weight and lasts much longer than its lead-acid counterparts. It’s longer life span provides exceptional lifetime value. The 20 ah of capacity provides ample power for high amp draw electronics for times when you need a longer run time. It’s suitable in many 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: fishing electronics, robotics, solar lighting, remote power, outdoor adventures 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.
