The Fogstar Drift Pro Gen2 12V LiFePO4 Leisure Battery series represents the next generation of high-performance lithium storage for both marine and mobile leisure applications. Engineered using Grade A LiFePO4 cells, the Drift Pro Gen2 delivers outstanding power stability, ultra-long cycle life and reliability in all conditions—making it a perfect upgrade for yachts, cruisers, narrowboats, campervans, motorhomes and off-grid installations.

Each battery is built around Fogstar’s advanced BMS (Battery Management System) with enhanced protections, including low-temperature charging safeguards, short-circuit protection, over-current defence and real-time cell balancing. With exceptionally low weight compared to equivalent lead-acid batteries and significantly longer lifespan, the Drift Pro Gen2 offers outstanding value and long-term dependability.

Designed for demanding environments, the Drift Pro Gen2 holds up incredibly well in marine installations as a leisure/house battery, providing stable energy for navigation equipment, lighting, refrigeration, pumps, inverters and more. For road users, it’s equally ideal for campervans, motorhomes and 12V conversion builds, delivering consistent, fast-charging power for appliances and off-grid living.

Available in four high-capacity options—230Ah, 280Ah, 460Ah and 628Ah—this range ensures that every vessel or vehicle can be powered according to its exact needs.
