Felicity Solar Lithium Batteries FLS48100SG1

Q: How much energy does the FLS48100SG1 store?

5.12 kWh, which is 100 Ah at a nominal 51.2 V. A depth of discharge of ≥95% leaves nearly all of it usable, and eight modules in parallel take a bank to 40.96 kWh.

Q: What current can the FLS48100SG1 charge and discharge at?

60 A continuously, in either direction, with a 100 A peak for 15 s. The recommended everyday current is 50 A, inside an operating window of 44.8 V to 57.6 V with cut-off at 44.8 V.

Q: How many FLS48100SG1 modules can run in parallel?

8 modules. The bank scales from one module at 5.12 kWh to eight at 40.96 kWh, all on the same 51.2 V nominal bus, with CAN and RS485 for communication.

Q: How much does the FLS48100SG1 weigh and what warranty does it carry?

46 kg for a floor-mounted module of 600 x 450 x 180 mm. It ships in a 712 x 562 x 298 mm carton at 50 kg gross, is rated IP21, and the warranty is 5 Years.

A 100 Ah LiFePO4 battery module rated 60 A continuous and 100 A peak for 15 s, expandable from one to eight units sharing a single 51.2 V bus.

Models Covered: FLS48100SG1

Manufacturer: Felicity Solar

Application: The Felicity Solar FLS48100SG1 is a 51.2 V LiFePO4 battery module holding 5.12 kWh, or 100 Ah, rated for 60 A continuous charge and discharge with a 100 A peak for 15 s. One to eight modules run in parallel, taking a bank to 40.96 kWh on the same 51.2 V bus. The cells are rated beyond 6000 cycles, with depth of discharge rated separately at ≥95%. The operating window runs 44.8 V to 57.6 V, with cut-off at 44.8 V, a charging ceiling of 57.6 V and 50 A as the recommended everyday current. A built-in smart BMS works with a breaker and a fuse; the control module carries an LCD and the battery module 4 LEDs, with CAN and RS485 ports for monitoring. The module measures 600 x 450 x 180 mm, weighs 46 kg, stands on the floor and travels in a 712 x 562 x 298 mm carton at 50 kg gross. Charge from 0 to 55 °C, discharge from -20 to 55 °C, 5-95% humidity, below 2000 m, rated IP21, stored at 0-35 °C. We are an authorised Felicity Solar distributor and supply the FLS48100SG1 from our own stock. Warranty: 5 Years.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
