Built for 24V systems that demand precision and efficiency, this delivers 8,550Wh of usable energy with lower system current and improved power distribution. Constructed from Grade A EVE LF334 prismatic cells, it's ideal for 24V campervans, motorhomes, larger solar installations, narrowboats, and off-grid setups where reduced cable losses and higher system efficiency matter.
At its core, a 300A Smart BMS with 0.2A shunt accuracy and an integrated 2A active cell balancer keeps every cell in perfect balance — improving cycle life, efficiency, and consistent output over years of use. Built-in low-temperature heating protects the cells in cold weather, enabling safe charging even when temperatures drop below zero. Fully IP67-rated for complete water and dust protection.
Bluetooth monitoring via the free Fogstar Drift App gives real-time access to voltage, current, temperature, and state of charge. Full Victron plug-and-play compatibility, a physical on/off switch, and M8 terminal posts ensure clean integration into professional off-grid electrical systems.
Backed by a 10-year warranty with UK-based technical support.

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.

A premium LiFePO4 leisure battery built around Grade A EVE LF334 prismatic cells, delivering 4,275Wh of usable energy in a compact, robust housing. Engineered in the UK, this is one of the most capable 12V lithium batteries available for campervans, motorhomes, caravans, narrowboats, off-grid cabins, and solar energy storage systems.
Powering it all is a next-generation 300A Smart BMS with 0.2A shunt accuracy and integrated active cell balancing, giving you precise state-of-charge data, higher power handling, and longer cell life. A built-in low-temperature heating system automatically warms the cells before charging begins, so you can charge safely in sub-zero conditions without risk of damage. Fully IP67-rated, it handles damp lockers, marine environments, and year-round outdoor use without issue.
Real-time Bluetooth monitoring via the free Fogstar Drift App (iOS and Android) gives you live voltage, current, temperature, and state of charge at a glance. Plug-and-play Victron compatibility, an integrated fire suppression system, a physical on/off switch, and M8 terminals round off a battery built for clean, professional installs.
