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.
