Felicity FLH48100UMG1 High-Voltage Battery Module 5.12 kWh LiFePO4 51.2 V
The FLH48100UMG1 is the building block of the Felicity high-voltage tower: 51,2 V nominal, 100 Ah of capacity, 5.12 kWh per module. It stacks without external power cables, because the connection runs through the side contacts, and you add one module at a time as demand grows.
A cluster goes up to sixteen modules, 81.92 kWh, and the working voltage rises with it: this is the configuration high-voltage hybrid inverters want in order to work properly. The LiFePO4 cells give 6,000 cycles at 80 per cent depth of discharge and round-trip efficiency stays around 95 per cent.
It pairs with the control unit and BMS from the same G1 series, which closes the cluster and talks to the inverter over CAN and RS485. IP21 rating, so a dry plant room or garage. Ten-year manufacturer warranty. We ship within Italy and across the European Union.
