Low voltage storage battery Felicity FLA48280TG2-EU 14.3kWh LiFePO4 floor standing on wheels
The Felicity FLA48280TG2-EU is the second-generation LiFePO4 storage battery of the FLA range: 14.3kWh of nominal energy at 51.2V in a floor-standing tower module, mobile on wheels. The T in Felicity's naming rules stands for the tower format: this is not a wall battery, it sits on the floor and can be moved where needed.
The generation change shows in longevity: ≥8000 cycles declared, with a 95% depth of discharge. Communication is complete — CAN 2.0, RS485, Wi-Fi and Bluetooth — and protection is layered, with a smart BMS, breaker, fuse and MX+OF contacts, plus an integrated aerosol fire extinguisher and externally replaceable fuses. Up to 15 units in parallel for 214.5kWh. IP21 protection for indoor use.
