Fogstar Drift 12V 172Ah Lithium Leisure Battery

Fits like lead acid. Powered by Lithium.

The Fogstar Drift 12V 172Ah DIN Fit is built in a standard DIN case format, designed as a direct physical replacement for traditional lead acid leisure batteries. It delivers modern LiFePO4 performance with integrated protection, active balancing and CAN communication, making it ideal for campervans, motorhomes, boats and off-grid systems.

Key Features

250A Smart BMS for Reliable Power Delivery:
The integrated 250A Smart BMS manages protection, monitoring and power control for leisure and inverter-based systems. It protects against overcharge, over discharge, overcurrent, short circuit and temperature extremes while delivering stable performance.

Active Cell Balancer for Stable Operation:
A built-in active balancer maintains cell voltage alignment during operation. This supports efficiency, stability and long-term performance.

DIN Direct Replacement Design:
Manufactured in a standard DIN footprint, allowing installation into existing lead acid battery spaces without tray modification.

Victron CAN-BUS Compatibility:
Integrated CAN communication enables clean integration with compatible inverter systems. RS485 host and slave ports are also included.

Bluetooth Monitoring:
Monitor voltage, current, state of charge and temperature via Bluetooth connectivity.

Automatic Low-Temperature Heating:
The built-in heater automatically warms the battery to a safe temperature before charging, protecting the cells in cold weather.

Physical On/Off Switch:
Built-in output switch for safe isolation during installation or maintenance.

Premium EVE Prismatic Cells:
Built using Grade A EVE cells in a 4S1P configuration for consistent and stable performance.

Designed & Supported in the UK:
Backed by a 10-year warranty.
