The RB20-X is the smallest battery in the RELiON X-Series. Our X-Series batteries allow for higher peak and higher continuous discharge currents compared to our standard lithium batteries of the same size.
This is ideal if you have a physical size constraint but need higher power, or if you want to increase the power but you don’t need the extra energy that comes in our standard lithium offering.
Safe and lightweight the 12V 20Ah lithium iron phosphate battery is equipped with a flag terminal type and a built-in battery management system (BMS). All RELiON LiFePO4 batteries have installation flexibility, fast-charging capabilities and are maintenance free.
