This 12V 80 Ah lithium iron phosphate battery is a safer, more lightweight alternative to lead-acid in your marine, solar RV, or other applications. At 25 lbs, this battery is less than half the weight of a lead-acid equivalent, helping to fight against the drag cause by heavier options. It maintains consistent power and is equipped with handles for carrying, an M8 terminal type and features a built-in battery management system (BMS). The RB80 battery meets UL, UN, CE and IEC certifications.

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