Off-grid power made smarter with the enhanced engineering and accuracy of Drift Gen2.

If you need a reliable lithium leisure battery for campervans, motorhomes, boats, off-grid cabins or solar storage. This is the new benchmark.

Key Features

• 300A Smart BMS for High-Demand Systems:
  The next-generation 300A Battery Management System handles heavy loads with ease. Perfect for powerful inverter setups and demanding off-grid applications.
• 0.2A Shunt Accuracy:
  Drift Gen2 delivers highly accurate power monitoring, giving you tighter state-of-charge readings and more reliable system performance.
• Active Cell Balancer for Maximum Efficiency:
  A built-in active balancer keeps every cell perfectly aligned. This boosts efficiency, improves cycle life and maintains consistent output.
• Premium EVE Prismatic Cells:
  Built with Grade A LF304 EVE cells that deliver consistent performance, solid stability, strong safety and a long service life.
• Full Victron Plug-and-Play Integration:
  Drift Gen2 communicates cleanly with Victron systems for faster installation and more accurate system data.
• IP67 Waterproof and Dustproof:
  Fully sealed against water and dust. Ideal for marine installations, damp lockers and rugged environments.
• Bluetooth Monitoring via the Fogstar App:
  Track real-time voltage, current, SOC, temperature and more using the Fogstar Drift App for iOS and Android.
• Automatic Low-Temperature Heating:
  The built-in heater automatically warms the battery to a safe temperature before charging, protecting the cells in cold weather.
• Improved Hardware and Design:
  A custom lid, upgraded terminals and a physical on/off switch make installs cleaner and maintenance easier.
• Designed & Supported in the UK:
  Created by our award-winning engineering team with full UK-based technical support. Backed by a 10-year warranty.
