Fogstar Drift PRO Gen2 12V 230Ah Lithium Leisure Battery

With 2,944Wh of usable energy, the Drift PRO 12V 230Ah Gen2 delivers reliable, high-performance power for campervans, motorhomes, boats, and off-grid systems.

This latest generation introduces major system upgrades, including integrated active balancing and multi-battery CANbus communication – making the Drift PRO plug-and-play compatible with Victron Cerbo GX systems running multiple batteries.

Built with Grade A prismatic LiFePO₄ cells, a 300A Smart Battery Management System (BMS), and housed in a durable, serviceable metal case, the Drift PRO continues to set the benchmark for UK leisure and off-grid battery systems.

What's New in the Gen2?

Integrated Active Balancing: Now built-in – no external balancer required.

Battery-Linking via RJ45: Dedicated Battery-Link ports allow multiple Drift PRO units to communicate over CANbus with a single Victron Cerbo GX (or GX-enabled inverter).

Improved Internal Layout: Optimised for thermal management, cable routing, and long-term serviceability.
