About the Felicity Solar FLB48280TG1-AU 51.2V 14.3kWh LiFePO4 Battery

The Felicity Solar FLB48280TG1-AU is a floor-mounted 51.2V LiFePO4 battery rated at 14.3kWh of nominal energy, weighing 115Kg net in a cabinet of 895×450×235mm, with a 95% depth of discharge, 150A of continuous charge and discharge current, and a 300A peak for 15s. Continuous power is 7680W in each direction, and the operating window runs 44.8-57.6V. The 14.3kWh figure is the nominal energy of the cells; how much of it leaves the pack in a cycle is governed by the separate 95% depth-of-discharge row. Charging is specified 0~55°C and discharging -20~55°C. Four interfaces are built in — CAN2.0, RS485, WIFI and Bluetooth — and an LED display reports state at the cabinet itself. Protection is integrated: BMS, Fuse, Breaker and MX+OF. Up to 32 units can be paralleled where one FLB48280TG1-AU is not enough, and the packed shipping weight is 124.5Kg. We are an authorised Felicity Solar distributor, and the FLB48280TG1-AU carries a 5 Years warranty.

Frequently Asked Questions

115Kg net, in a floor-mounted cabinet measuring 895×450×235mm. Packed for transport the unit weighs 124.5Kg in a 1013×588×342mm carton, so plan the delivery route and the floor position before it arrives rather than after.

95% is the published depth of discharge for the FLB48280TG1-AU. The 14.3kWh is the nominal energy of the cells; what the BMS releases in a cycle is governed by that separate depth-of-discharge figure, not by the nominal rating.

300A @ 15s. Continuous charge and discharge are both 150A, which is 7680W in each direction at the 51.2V nominal bus, so short surges are covered without sizing the whole installation around them.

Charge 0~55°C and discharge -20~55°C. The operating voltage window is 44.8-57.6V, and the battery carries a 5 Years warranty. We are an authorised Felicity Solar distributor.
