Fogstar Drift 12V 100Ah Lithium Leisure Battery

The Fogstar Drift 12V 100Ah lithium leisure battery is a /glossary/lifepo4-battery/LiFePO4 battery designed for /glossary/leisure-battery/leisure battery duties in caravans, campervans, marine installations and off-grid power systems where low weight, deep cycling and high usable capacity matter.

Fogstar positions this battery as a UK-designed and UK-supported lithium leisure battery with built-in Bluetooth, integrated heating and a 150A /glossary/battery-management-system-bms/BMS. Compared with a conventional lead-acid leisure battery, the Drift 12V 100Ah offers substantially lower weight, deeper usable discharge and faster charging behaviour, while retaining a compact form factor that suits many existing leisure battery spaces.

Why this product makes sense

For campervan, caravan and marine systems that are actually expected to do some work, lithium starts to make a lot more sense than pretending a conventional battery is having a lovely time. The Drift 12V 100Ah combines a 1200Wh energy rating with built-in low-temperature heating, Bluetooth monitoring through the Fogstar Drift App, and a 150A BMS that supports both high charge and discharge currents.

Fogstar rates the battery at 3000 cycles at 80% depth of discharge and backs it with a 10-year warranty. Maximum charge current is 150A, maximum discharge is 150A, charging voltage is 14.4V and discharge cut-off voltage is 10V. The battery can be used in series up to 48V and in parallel for higher capacity systems.
