Felicity Solar FLA24100PG2 25.6V 2.56kWh LiFePO4 Battery features

350 × 306 × 185 mm for 19.5 kg

A compact enclosure for a 25.6 V pack: 350 mm wide, 306 mm high and 185 mm deep, weighing 19.5 kg, with a 22 kg packed carton.

3,750 W continuous charge and discharge

The FLA24100PG2 sustains 3,750 W of charge or discharge power continuously, and accepts 150 A as a 15-second peak current.

16 units in parallel for 40.96 kWh

Paralleling is capped at 16 pcs, which builds a 40.96 kWh bank on a 25.6 V bus.

22.4-28.8 V operating window

Nominal voltage is 25.6 V and the module operates anywhere between 22.4 V and 28.8 V.

IP21 enclosure, 2.56 kWh nominal

The housing carries an IP21 protection degree, and the 2.56 kWh rating is nominal energy, governed by the separate >95% depth-of-discharge figure.

More than 6,000 cycles, warranty of 5 Years

Cycle life is rated at more than 6,000 cycles, quoted as a bare count, and the module is covered by a warranty of 5 Years.

About the Felicity Solar FLA24100PG2 25.6V 2.56kWh LiFePO4 Battery

The Felicity Solar FLA24100PG2 is a 25.6 V battery module rated at 2.56 kWh of nominal energy, weighing 19.5 kg in a 350 × 306 × 185 mm IP21 enclosure. It charges and discharges continuously at 3,750 W, works anywhere across a 22.4-28.8 V window, and scales to 16 units in parallel for 40.96 kWh. We are an authorised Felicity Solar distributor and supply the FLA24100PG2 from our own stock. That 3,750 W is a continuous rating rather than a burst; on top of it the pack accepts 150 A of charge or discharge current as a 15-second peak. Depth of discharge is rated separately at >95%, and cycle life is rated at more than 6,000 cycles — a bare count the record publishes with no test conditions beside it. At 19.5 kg the module is light enough to carry up a stair by hand, and the packed carton weighs 22 kg. It is supplied with a warranty of 5 Years.

Frequently Asked Questions

19.5 kg, in an enclosure 350 mm wide, 306 mm high and 185 mm deep. The packed carton weighs 22 kg, which is the figure to plan the carry around rather than the 19.5 kg of the module on its own.

3,750 W continuously. Peak current is a separate rating at 150 A for 15 seconds, and the module works across a 22.4-28.8 V window around its 25.6 V nominal voltage.

Up to 16 pcs in parallel, for 40.96 kWh on a 25.6 V bus. Each module brings 2.56 kWh of nominal energy to the bank.

IP21 for the enclosure, and a warranty of 5 Years. Cycle life is rated at more than 6,000 cycles and depth of discharge separately at >95%; the record attaches test conditions to neither.
