About the Felicity Solar FLB48205WG1 51.2V 10.5kWh LiFePO4 Battery

The Felicity Solar FLB48205WG1 is a 205 Ah LiFePO4 battery storing 10.5 kWh at 51.2 V nominal, with cycle life rated at ≥6000, depth of discharge published separately at >95%, and thirty-two units allowed in parallel for a maximum system capacity of 336 kWh. The cabinet itself measures 683×258×450 mm and weighs 86.5 kg; boxed for transport it becomes 778×438×548 mm and 106 kg, so the two weights are not interchangeable when a lift is being planned. Continuous charge and discharge current is 150 A, the recommended working current is 100 A, and 200 A is available as a 15-second peak. The pack cuts off at 44.8 V and charges no higher than 57.6 V. Inside the IP65 enclosure sit a built-in smart BMS, a breaker and a fuse; an LED shows status while CAN and RS485 report to the inverter. Charging is allowed from 0 °C to 55 °C, discharging from -20 °C to 55 °C, storage from 0 °C to 35 °C, humidity from 5% to 95%, altitude below 2000 m. The certification is UN38.3 and the warranty is 5 Years. We are an authorised Felicity Solar distributor and supply the FLB48205WG1 from our own stock.
