Fits Like Lead Acid. Powered by Lithium.

Introducing the Fogstar Drift 12V 172Ah DIN Fit

Upgrading from lead acid to lithium used to mean changing battery trays, reworking cabling, or squeezing a different battery shape into a space that wasn’t designed for it.

The Fogstar Drift 12V 172Ah DIN Fit solves that problem.

Built in a standard DIN case format, this battery is designed to drop straight into the same space as a traditional lead acid leisure battery. Same footprint, same mounting points, same simple installation. The difference is what’s inside.

Instead of ageing lead acid technology, you get modern LiFePO4 performance, advanced battery management and long-term reliability.

Let’s take a closer look.

🔋 Designed as a Direct Lead Acid Replacement

One of the biggest barriers to upgrading to lithium has always been physical fitment. Many campervans, motorhomes and boats are built around DIN-sized battery trays, leaving little room for alternative battery shapes.

The Drift DIN battery solves this by using a standard DIN footprint, meaning it fits into existing battery compartments without modification.

Why it matters:

• No tray modifications required
• Existing clamps and mounting systems still fit
• Straightforward upgrades for vans, boats and off-grid setups

You get the benefits of lithium without redesigning your entire electrical layout.

⚡ Reliable Power with a 250A Smart BMS

At the heart of the battery is a 250A Smart Battery Management System (BMS) designed to monitor and protect the entire pack.

The BMS constantly checks operating conditions and protects the battery against:

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

These safeguards ensure the battery operates safely while still delivering consistent power for leisure and inverter-based systems.

For users running inverters, off-grid appliances or demanding electrical setups, this protection is essential.

🌡️ Automatic Low Temperature Heating

Cold temperatures can make charging lithium batteries difficult. The Drift DIN battery solves this with integrated heating pads controlled by the BMS.

If the internal temperature drops to 0°C, charging is paused and incoming current is redirected to gently warm the cells. Once the battery reaches 5°C, charging resumes automatically.

Why it matters:

• Protects the battery during winter charging
• Prevents cell damage from low temperature charging
• Ideal for campervans, boats and off-grid systems

📱 Bluetooth Monitoring with the Fogstar Drift App

Every Drift DIN battery includes Bluetooth connectivity, allowing you to monitor the battery directly from your phone.

Using the Fogstar Drift App, you can view real-time data such as:

• Voltage
• Current
• State of Charge (SOC)
• Temperature

The app connects directly to the battery’s BMS, giving you a clear view of system performance without needing additional monitoring equipment.

For users managing off-grid systems or travelling long distances, having that visibility makes a big difference.

🔗 Ready for System Integration

The Drift DIN battery is designed to work in both simple and advanced electrical systems.

Communication and monitoring options include:

• CAN bus integration for compatible inverter systems
• RS485 communication ports
• Bluetooth monitoring via the Fogstar Drift App

When connected to compatible systems such as Victron GX devices, the battery can transmit detailed operating data including voltage, SOC, temperature and alarm states.

🇬🇧 Designed and Supported in the UK

Every Fogstar Drift battery is backed by a 10-year warranty and supported by a UK-based technical team.

Whether you're installing it in a campervan, marine system or off-grid cabin, the goal is simple: dependable power, straightforward installation, and long-term reliability.

The Simple Way to Upgrade to Lithium

The Fogstar Drift 12V 172Ah DIN Fit keeps installation simple while delivering the full benefits of lithium technology.

It fits where lead acid fits.

But inside, it delivers far more usable capacity, stable voltage, and significantly longer service life.

If you're upgrading an existing system or building a new one around a DIN battery space, this is lithium made easy.
