Introducing the Fogstar Drift 12V 172Ah DIN Fit

A DIN-format lithium battery built for straightforward upgrades and professional system integration.

The Fogstar Drift 12V 172Ah DIN Fit is designed for systems that require a lithium battery that fits directly into existing lead-acid battery spaces, without the headaches that usually come with non-standard case sizes.

Built in a standard lead acid housing, it offers a direct physical replacement for traditional lead acid leisure batteries while delivering the performance, monitoring and protection benefits of modern LiFePO4 technology.

For campervans, motorhomes, marine systems and off-grid installations, that means less time spent adapting trays or reworking battery spaces, and more time focusing on the wider system.

✔ Standard DIN Fitment for Simpler Upgrades

One of the key advantages of the Fogstar Drift 12V 172Ah DIN Fit is its case format. For installers working on retrofit projects, this allows the battery to be installed into existing lead acid battery locations with minimal disruption.

This is particularly useful where space is restricted or where maintaining the original battery footprint simplifies the installation.

Key benefits:

• Direct fit into standard DIN battery spaces
• Reduced need for tray or bracket modification
• Cleaner lead acid to lithium upgrades
• Suitable for campervan, motorhome and marine applications

✔ 250A Smart BMS with Integrated Protection

The battery is built around a 250A Smart BMS, providing protection, monitoring and operational control within a single integrated system.

Protection functions include:

• Overcharge protection
• Over discharge protection
• Overcurrent protection
• Short circuit protection
• Temperature protection

For installers, this gives a robust foundation for use in leisure and inverter-based systems where stable operation and fault protection are essential.

✔ Integrated Heating for Low Temperature Charging

The Drift DIN includes integrated low temperature heating, managed automatically by the BMS.

If you're trying to charge the battery and internal battery temperature drops to 0°C, incoming current is redirected to heat the cells. Once the pack reaches 5°C, charging resumes automatically.

This feature is particularly relevant for vehicle, marine and off-grid installations where batteries may be exposed to low ambient temperatures and charging protection is required without additional external heating systems.

✔ Bluetooth Monitoring and System Visibility

Bluetooth connectivity is built in as standard, allowing battery monitoring through the Fogstar Drift App.

Installers and end users can access live battery data including:

• Voltage
• Current
• State of Charge
• Temperature

This gives clear visibility of battery status without requiring separate monitoring hardware for basic diagnostics and everyday checks.

✔ CAN and RS485 Communication for System Integration

The Drift DIN is designed for both standalone and integrated installations, with support for:

• CAN communication
• RS485 host and slave ports
• Bluetooth monitoring

For compatible systems, including Victron GX devices, the battery can provide key operating data such as voltage, current, SOC, temperature and alarm states. This supports cleaner integration in monitored leisure and off-grid systems.

For installers working on communication-based lithium systems, this allows the battery to slot into more advanced setups without relying solely on voltage-based charging logic.

✔ Built for Scalable Installations

The Drift DIN also supports larger system builds where increased capacity or higher system voltage is required.

Configuration options include:

• Up to 16 batteries in parallel
• Up to 4 batteries in series for systems up to 48V

This gives installers flexibility when specifying systems for different customer requirements, from single-battery upgrades through to larger off-grid banks.

✔ Designed for Professional Installation

The overall proposition is simple. The Fogstar Drift 12V 172Ah DIN Fit gives installers a lithium battery that:

• fits standard lead acid battery spaces
• includes integrated protection and monitoring
• supports low temperature charging protection
• offers CAN and RS485 communication
• scales across larger system builds

For retrofit work especially, that combination makes it a practical option where clean fitment and modern battery functionality are both priorities.

Conclusion

The Fogstar Drift 12V 172Ah DIN Fit is designed to make DIN-format lithium upgrades more straightforward for installers.

It retains the fitment advantages of traditional lead acid battery sizing while adding the core benefits expected from a modern LiFePO4 system: smart BMS protection, Bluetooth monitoring, integrated heating and communication support.

For professional installers working on campervan, motorhome, marine and off-grid systems, it provides a strong balance of compatibility, functionality and ease of integration.
