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.
Backed by a 10-year warranty with UK-based technical support.
