RKL48-620 (48V 620AH at 0.2C discharge rate)
48V 620AH at 0.2C discharge rate Lithium (LiFePO4) Battery
48V 620AH at 0.2C discharge rate 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.
