REKOSER LiFePO4 RKL12-55 (12.8V 55AH)

Rekoser Lithium (LiFePO4) Battery

Rekoser Rekoser Lithium (LiFePO4) battery. Lithium Iron Phosphate (LiFePO4) Battery offers up to 20 times longer cycle life and five times longer float/calendar life than lead acid battery. About 40% of the weight of a comparable lead acid battery. RKL is a 'drop in' replacement for lead acid batteries. BMS built-in.
