About the Felicity Solar FLA48100 51.2V 5.12kWh LiFePO4 Battery

The Felicity Solar FLA48100 is a 51.2 V LiFePO4 battery holding 5.12 kWh of nominal energy from a 100 Ah cell string, sustaining 100 A of continuous charge and discharge current, and paralleling to 15 units for a 76.8 kWh maximum system capacity. Warranty is 7 Years. That 5.12 kWh is a nominal rating, not the energy released per cycle: the depth-of-discharge row sits apart at ≥95%, and cycle life is quoted as 6,000 cycles. Recommended everyday operation is 100 A, or 5,000 W, while short bursts are rated separately at 150 A and 7,500 W held for 15 seconds. The window runs 44.8 V to 57.6 V, cutting off at 44.8 V and charging no higher than 57.6 V. A built-in Smart BMS, a breaker and a fuse handle protection, CAN and RS485 carry pack data, and an LCD with LED indicators reports at the unit. It mounts on a wall or on the floor, weighs 48 kg, is rated IP21 and charges from 0 to 55 °C. Packed it is 55 kg in a 782 x 262 x 522 mm carton. We are an authorised Felicity Solar distributor and supply the FLA48100 from our own stock.

Frequently Asked Questions

How much energy does the FLA48100 store?

5.12 kWh of nominal energy, taken from a 100 Ah cell string on a 51.2 V nominal bus. That is a nominal rating; how much of it is drawn per cycle follows the separate depth-of-discharge row, listed at ≥95%.

How many FLA48100 units can run in parallel?

15 units, which is a maximum system capacity of 76.8 kWh on one 51.2 V bus.

What current and power can the FLA48100 handle?

100 A of continuous charge and discharge, or 5,000 W as the recommended power, with a separate 15-second ceiling of 150 A and 7,500 W.

What warranty and weight apply to the FLA48100?

7 Years is the warranty term. The unit itself weighs 48 kg and travels at 55 kg gross in a 782 x 262 x 522 mm carton, so plan handling around the packed figure.
