6.4kWh of 48V LiFePO4 power — built for serious off-grid energy storage.
The Fogstar Drift 48V 125Ah Gen 2 is a high-capacity lithium battery designed for off-grid homes, cabins, shepherd's huts, and rural properties running 48V solar or energy storage systems. With 6,400Wh of usable capacity and a 150A BMS, it delivers the kind of reliable, long-cycle performance that static off-grid installations demand.
Built on Grade A EVE LiFePO4 prismatic cells, this battery handles 4,000+ cycles at 80% depth of discharge — that's over a decade of daily cycling. The integrated heating system allows safe charging down to -20°C, making it a solid choice for unheated outbuildings and year-round rural use.
Bluetooth 5.0 monitoring via the Fogstar Drift app (iOS and Android) gives you real-time visibility of state of charge, voltage, and temperature. Native CAN/RS485 communication provides plug-and-play compatibility with Victron, Pylontech, Growatt, Solis, and Sofar inverters.
Stack up to 16 units in parallel for a maximum bank of 102.4kWh — scalable as your energy needs grow.
