About the Felicity Solar LPBF48350 51.2V 17.5kWh LiFePO4 Battery

The Felicity Solar LPBF48350 is a floor-mounted LiFePO4 battery of 350Ah and 17.5kWh nominal energy that works over a narrow 48-57.6V window: discharging stops at the 48V cut-off and charging is capped at 57.6V. Depth of discharge is rated separately at >95% and cycle life above 6000 cycles. The recommended charge and discharge point is 120A and 6000W, with a 15-second peak of 200A rated at 10000W. Six units is the parallel ceiling, giving a maximum system capacity of 105kWh, so this is the pack for a bank sized in tens rather than hundreds of kilowatt-hours. Charging is rated 0-55 °C and discharging -20 to 60 °C. Communication is CAN and RS485, the display is LCD and LED, and protection is a built-in smart BMS with breaker and fuse behind an IP21 enclosure. The unit weighs 162 kg and its carton weighs 185 kg, measuring 718 x 450 x 1112mm. Warranty is 5 Years. We are an authorised Felicity Solar distributor and supply the LPBF48350 from our own stock.
