About the Felicity Solar FLA48100UG1 51.2V 5.12kWh LiFePO4 Battery

The Felicity Solar FLA48100UG1 is a 5.12 kWh LiFePO4 battery module built on a 51.2 V nominal bus. It charges and discharges at 100 A continuous, or 5,000 W, peaks at 125 A and 6,250 W for 15 seconds, and stacks up to 32 units in parallel for 163.84 kWh in a single bank. Across a 44.8-57.6 V operating window the FLA48100UG1 is rated for a depth of discharge above 95%, a figure the record lists on its own row and separately from the 5.12 kWh nominal energy, so the two are read together rather than as one usable number. Cycle life is quoted as 6,000 cycles under the stated test conditions of 25°C±2°C, 0.5C/0.5C, 90% DOD and 70% EOL. The module installs stacked, weighs 43 kg net, and occupies 575 × 483 × 133 mm; the enclosure is rated IP21 and an LED display reports state locally. Warranty is 5 Years. We are an authorised Felicity Solar distributor and supply the FLA48100UG1 from our own stock.

Frequently Asked Questions

How much energy does the FLA48100UG1 store?

5.12 kWh of nominal energy at a 51.2 V nominal voltage, with the module working across a 44.8-57.6 V range. Depth of discharge is rated above 95% and is listed as its own row, so the 5.12 kWh figure is nominal energy and should not be read as a usable-capacity number.

What power and current can the FLA48100UG1 deliver?

5,000 W of continuous charge or discharge power, rising to 6,250 W for a 15-second peak. In current terms that is 100 A continuous and 125 A peak, both taken on the 51.2 V bus.

How many FLA48100UG1 units can be connected in parallel?

Up to 32 units in parallel, which brings a single bank to 163.84 kWh. Installation is stacked, and each module is 43 kg net (47 kg gross) and measures 575 × 483 × 133 mm.

How long does the FLA48100UG1 last and what warranty does it carry?

6,000 cycles under the test conditions quoted with the rating, namely 25°C±2°C, 0.5C/0.5C, 90% DOD and 70% EOL. Warranty is 5 Years, the enclosure is rated IP21, and an LED display shows the state of the module.
