About the Felicity Solar FLA12171-EU 12.8V 2.2kWh LiFePO4 Battery

The Felicity Solar FLA12171-EU is a 12.8 V LiFePO4 battery holding 2.2 kWh of nominal energy, rated for a maximum 200 A of charge and discharge current and a maximum 2500 W of charge and discharge power, each held for 15 seconds. Depth of discharge is rated separately at ≥95%, and cycle life at ≥6000 cycles. The working window runs 11.2-14.4 V around that 12.8 V bus, and up to 16 FLA12171-EU units wire in parallel to build a 35.2 kWh bank from a single model. The block itself weighs 15 kg net and measures 328 × 248 × 199 mm; packed for transport it is a separate 18 kg in a 391 × 310 × 257 mm carton, so the 15 kg net figure describes the unit and not the shipment. It stands on the floor, carries a built-in smart BMS and a fuse, reports its state on an LCD and LED display, and speaks RS485 and CAN to a compatible inverter. The FLA12171-EU is covered by a 5 Years warranty. We are an authorised Felicity Solar distributor and supply the FLA12171-EU from our own stock.
