About the Felicity Solar FLA48300 51.2V 15kWh LiFePO4 Battery

The Felicity Solar FLA48300 is a 51.2 V LiFePO4 battery rated 300 Ah and 15 kWh of nominal energy, sustaining 150 A of continuous charge and discharge current at a recommended 120 A, with a 15-second ceiling of 200 A and 10,000 W, and paralleling to 15 units for a 225 kWh maximum system capacity. Warranty is 7 Years. The 15 kWh is nominal energy; the depth-of-discharge row stands apart at ≥95%, and rated life is 6,000 cycles. Voltage runs from a 44.8 V cut-off to a 57.6 V charging ceiling. Protection combines a built-in Smart BMS, a breaker and a fuse, CAN and RS485 hand pack data to a compatible inverter, and an LCD reports locally. The cabinet weighs 135 kg and takes either a wall or a floor; packed it is 160 kg in a 635 x 498 x 1150 mm carton, and that packed figure is the one to plan handling around. It is rated IP21, charges from 0 to 55 °C, discharges from -20 to 55 °C, stores at 0-35 °C, tolerates 5-95% humidity and operates below 2000 m. We are an authorised Felicity Solar distributor and supply the FLA48300 from our own stock.
