Serious capacity in a single battery. Built on Grade A EVE LF334 prismatic cells in a 4S2P configuration, this delivers 8,550Wh of usable energy, making it the highest-capacity single 12V LiFePO4 leisure battery in the Fogstar Drift Gen2 range. Purpose-built for expedition campervans, motorhomes, off-grid cabins, marine systems, and large-scale solar storage.
High-current performance comes from a 300A Smart BMS with 0.2A shunt accuracy and a 2A active cell balancer, keeping every cell in perfect alignment for consistent output and maximum cycle life. Built-in low-temperature heating allows safe charging in sub-zero conditions, while the IP67-rated enclosure provides complete protection against moisture and dust — equally suited to boat bilges, damp lockers, and harsh outdoor environments.
Bluetooth monitoring via the Fogstar Drift App delivers live voltage, current, temperature, and SOC data. Plug-and-play Victron Cerbo GX integration, a physical on/off switch, and M8 terminal posts make this a professional-grade battery that is straightforward to install and scale.
Backed by a 10-year warranty with UK-based technical support.
