Relion Safety Icon

 Lithium Iron Phosphate (LiFePO4)

Relion's LiFePO4 cells are inherently made to be safe; so much so we consider them to be the safer than lead-acid. And if you don't take our word for it, they have passed over 7 major Safety & Stress tests, contain absolutely no acid, generate no gas emissions and are highly recyclable.

 

This efficient and fast-charging 12V 50Ah lithium iron phosphate battery is equipped with an M8 terminal type and built-in overcharge protection. The RB50 battery meets UL, UN, CE and IEC certifications.

All RELiON LiFePO4 batteries have installation flexibility, fast-charging capabilities and are maintenance free.

Compared to lead-acid and other lithium batteries, lithium iron phosphate batteries offer significant advantages, including improved discharge and charge efficiency, longer life span and the ability to deep cycle while maintaining power. LiFePO4 batteries often come with a higher price tag, but a much better cost over life of the product. No maintenance and super long life makes them a worthwhile investment and a smart long-term solution.
