About the Felicity Solar FLA12100 12.8V 1.28kWh LiFePO4 Battery

The Felicity Solar FLA12100 is a 12.8 V LiFePO4 battery rated 100 Ah, or 1.28 kWh of nominal energy, housed in a floor-mounted 295 x 199 x 201 mm case weighing 10 kg. Its depth of discharge is rated ≥95%, cycle life beyond 6000 cycles, and continuous charge and discharge current reaches 100 A. Up to 16 units wire in parallel, so the same model reaches a maximum system capacity of 20.48 kWh. Everyday cycling is rated at 100 A and 1250 W, while a 15 second peak takes or delivers 150 A, or 1875 W. Charging tops out at 14.4 V, float sits at the same 14.4 V, the cut-off is 12 V and the operating window runs 11.2-14.4 V. A built-in Smart BMS and a fuse handle protection, an LED display reports state, and CAN and RS485 talk to a compatible inverter. Charge from 0 to 55 °C, discharge from -20 to 55 °C, behind an IP21 enclosure certified to UN38.3. Packed for transport the block measures 357 x 261 x 263 mm and weighs 12 kg. We are an authorised Felicity Solar distributor and supply the FLA12100 from our own stock, and the warranty is 5 Years.

Frequently Asked Questions

How much energy does the FLA12100 store?

1.28 kWh of nominal energy — 100 Ah on a 12.8 V nominal bus. The depth of discharge is rated ≥95%, so nearly all of that figure is available, and the LiFePO4 cells are rated beyond 6000 cycles.

How many FLA12100 batteries can be wired in parallel?

16 units, which caps the maximum system capacity at 20.48 kWh. Every unit reports over CAN and RS485, so the bank presents itself to a compatible inverter as one pack rather than sixteen.

What charge and discharge current does the FLA12100 accept?

100 A continuously in either direction, which is also the maximum charging current and the recommended rate, worth 1250 W in daily use. For 15 seconds it will take or deliver 150 A, or 1875 W. Maximum charging voltage is 14.4 V, float is 14.4 V and the cut-off is 12 V.

How much does the FLA12100 weigh and what does it measure?

10 kg, in a floor-mounted case of 295 x 199 x 201 mm. Boxed for transport it measures 357 x 261 x 263 mm and weighs 12 kg, so size the shelf from the 295 mm figure, not the carton. The enclosure is IP21, charging runs 0 to 55 °C and discharging -20 to 55 °C.
