Fogstar Drift Gen2 12V 300Ah Lithium Leisure Battery

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

The Fogstar Drift Gen2 12V 300Ah LiFePO4 Battery delivers higher accuracy, tougher engineering and smarter performance than the original Drift range. Every major component has been re-engineered for better accuracy, power handling and efficiency.

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.
