Fogstar Drift Gen2 12V 668Ah Lithium Battery
The Fogstar Drift Gen2 12V 668Ah is an 8.55kWh LiFePO₄ lithium battery that gives you very large 12V storage in a single IP67 case, in place of a tangle of smaller batteries. With a 300A smart BMS, built-in heating and a CAN port for Victron GX systems, it suits large motorhomes, live-aboard boats, off-grid cabins and high-demand 12V solar systems.

- 300A smart BMS with 2A active balancer and a 0.2A accuracy shunt
- Built-in heating warms the cells before charging in cold conditions (0°C to 10°C)
- IP67 rated enclosure with internal fire suppression and a physical on/off switch

- Bluetooth monitoring through the Fogstar Drift app
- M8 terminals with bolts included, and a 10-year warranty
IP67 heated lithium battery for cold, damp and marine locations
At 8.55kWh it is one of the largest 12V batteries available as a single unit, which keeps wiring simple and the number of connections low. The 300A BMS supports large inverters, the heater allows charging in cold weather, and the IP67 case with internal fire suppression copes with damp engine bays, lockers, boats and outbuildings.
Victron Cerbo GX connection and Bluetooth monitoring
The smart BMS reports voltage, current, state of charge and temperature over Bluetooth to the Fogstar Drift app. For Victron systems the battery has a CAN port that connects to a Cerbo GX or GX-enabled inverter through VE.Can port 2, so the BMS can pass charge and discharge limits to the system. A 2m extension CAN cable is available if the supplied one is too short.
Building a larger battery bank
Connect up to 16 in parallel to increase capacity. For 48V systems, see our 48V modular battery stacks. Keep batteries in a bank the same model and age. Other Drift Gen2 sizes: 12V 334Ah, 24V 334Ah, 24V 230Ah. You can also browse the full Fogstar lithium battery range.
Size, weight and mounting
635mm x 244mm x 220mm (L x W x H) and approximately 56kg. Plan lifting and mounting before it arrives. A matching Drift bracket is available separately.

Frequently asked questions
Does the 12V 668Ah Drift Gen2 work with Victron?
Yes. It has a CAN port that connects to a Cerbo GX or GX-enabled Victron inverter, so the BMS can control charging and discharging.
Can it be charged in cold weather?
The built-in heater warms the cells before charging in cold conditions, so it can be used in unheated locations. The BMS also protects the cells from low-temperature charging.
How many cycles will it last?
The cells are rated for 4,000 cycles at 80% depth of discharge, and the battery has a 10-year warranty.
Warranty and support
Backed by a 10-year warranty and UK-based technical support.
