Description
When only the very best will do, the Fogstar Drift PRO 12V 628Ah Gen2 delivers unmatched capacity and performance for the most demanding off-grid applications. Whether you’re powering a professional overland vehicle, a liveaboard boat, or a large-scale solar system, this battery delivers a staggering 8,038Wh of reliable, intelligent energy storage.
Built with Grade A EVE MB31 LiFePO₄ prismatic cells, the Drift PRO Gen2 is optimised for longevity, consistency, and efficiency. The integrated 300A Smart BMS offers full protection against over-voltage, under-voltage, over-current, short circuits, and low-temperature charging. The internal heating system enables safe operation even in sub-zero temperatures.
Connectivity and control are key strengths of this battery. With dedicated Battery-Link RJ45 ports, multiple Drift PRO units can be connected in a CANbus network and integrated directly into a Victron Cerbo GX system. Real-time Bluetooth monitoring is also built in via the Fogstar Drift App, providing insights into state of charge, temperature, cell voltages, and cycle count – all from your phone.
Despite its enormous capacity, the Drift PRO 628Ah weighs just 60.23kg, thanks to an energy-dense design that’s significantly lighter and more compact than equivalent lead-acid systems. The serviceable metal case with M10 terminals ensures long-term durability and field-repairability.
Designed and developed in the UK, and supported by a 10-year warranty and in-house customer service, this battery is the perfect long-term investment for anyone who needs serious off-grid reliability.
