Felicity FLS48100SMG1 Low-Voltage Stackable Battery Module 5.12kWh LiFePO4
The FLS range is Felicity's 48V tower: the same idea as the high-voltage systems, but with the voltage staying at 51.2V and therefore compatible with every low-voltage hybrid inverter commonly fitted. The FLS48100SMG1 is the 5.12kWh expansion module.
It stacks onto the BMS base from the same series and gets added as consumption grows: no external power cables, no separate cabinet to buy. LiFePO4 cells, 100Ah, 51.2V nominal.
At least one FLS48100SCG1 base is required to close the group and talk to the inverter. Ten-year manufacturer warranty. We ship within Italy and across the European Union.
