About the Felicity Solar LPBF12300 12.8V 3.75kWh LiFePO4 Battery

The Felicity Solar LPBF12300 is a 12.8 V LiFePO4 battery rated 300 Ah, or 3.75 kWh of nominal energy, with a depth of discharge above 95% and a cycle life beyond 6000 cycles. It weighs 34 kg, measures 492 x 245 x 381 mm, stands on the floor and cuts off at 11.2 V. Charging tops out at 14.4 V, so the working window is 11.2-14.4 V. Felicity Solar rates 150 A, or 1875 W, as the recommended continuous charge and discharge current, with 200 A and 2500 W available for 15 s peaks. Sixteen LPBF12300 units can be paralleled to a maximum system capacity of 60 kWh. A built-in Smart BMS and fuse handle protection, while CAN and RS485 carry state of charge to a compatible inverter and an LCD with LED indicators repeats it at the unit. Charge between 0-55 °C and discharge from -20 to 55 °C; the IP21 enclosure is an indoor one. The cells carry UN38.3, packed weight is 38 kg in a 560 x 303 x 450 mm carton, and the warranty is 5 Years. We are an authorised Felicity Solar distributor and supply the LPBF12300 from our own stock.
