About the Felicity Solar FLA48250 51.2V 12.5kWh LiFePO4 Battery

The Felicity Solar FLA48250 is a 51.2 V LiFePO4 battery rated 250 Ah and 12.5 kWh of nominal energy, running 150 A of continuous charge and discharge current, which is also its recommended figure and worth 7,500 W, and paralleling to 15 units for a 187 kWh maximum system capacity. Warranty is 5 Years. The 12.5 kWh is a nominal rating, not the energy delivered per cycle; what comes out follows the depth-of-discharge row, which the record carries separately at ≥95%, alongside a life of 6,000 cycles. Short bursts are rated apart at 200 A and 10,000 W over 15 seconds. The pack works from 44.8 V to 57.6 V, cutting off at 44.8 V. A built-in Smart BMS, a breaker and a fuse cover protection, CAN and RS485 report to a compatible inverter, and an LCD with LED indicators reports at the unit. It weighs 97 kg, takes a wall or a floor, is rated IP21, and charges from 0 to 55 °C. Packed it is 115 kg in a 900 x 450 x 570 mm carton. We are an authorised Felicity Solar distributor and supply the FLA48250 from our own stock.

Frequently Asked Questions

How much energy does the FLA48250 hold?

12.5 kWh of nominal energy, from 250 Ah at 51.2 V nominal. Depth of discharge is rated separately at ≥95%, so the two rows are read side by side rather than as one usable figure.

What is the largest bank the FLA48250 supports?

187 kWh, reached by paralleling up to 15 units on one 51.2 V bus.

How much current does the FLA48250 sustain?

150 A of continuous charge and discharge, which is the recommended figure too and equals 7,500 W; a separate 15-second rating allows 200 A and 10,000 W.

How heavy is the FLA48250 and what warranty applies?

97 kg for the unit and 115 kg once packed into its 900 x 450 x 570 mm carton, with a 5 Years warranty.
