Description
The RELiON RB24V20 is a compact 24V 20Ah lithium iron phosphate battery – perfect in many applications, including solar energy systems. It maintains consistent power and is equipped with an M8 terminal type and a built-in battery management system (BMS). The RB24V20 battery meets UL, CE and IEC certifications.
All RELiON LiFePO4 batteries have installation flexibility, fast-charging capabilities and are maintenance free.
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.
