About the Felicity Solar FLS48050SMG1 51.2V 2.56kWh LiFePO4 Battery

The Felicity Solar FLS48050SMG1 is a floor-mounted battery module rated 50 Ah and 2.56 kWh at a nominal 51.2 V. Its system operating voltage runs from 44.8 V to 57.6 V, its cycle life is rated at more than 6000 cycles, and its depth of discharge is rated at ≥95%. We are an authorised Felicity Solar distributor and supply the FLS48050SMG1 from our own stock. The battery designation for this unit reads 150/102/[1P16S]M/-10+50/95, reproduced exactly as it is written and left uninterpreted. Working temperature is stated per direction: charging from 0°C to 55°C, discharging from -20°C to 55°C, with storage from 0°C to +35°C and an altitude limit below 2000 m. The two ratings that govern how much of the 2.56 kWh can be drawn are published side by side rather than merged: a nominal module energy of 2.56 kWh and a depth of discharge of ≥95%. Mounting is on the floor, the approximate product weight is 31 kg, and the package measures 642 x 462 x 337 mm. The warranty term is 5 Years.
