Fortress Power Heat Mat Kit

The Fortress Power Heat Mat Kit is a self-regulating battery heating accessory engineered specifically for DuraRack installations in cold climates, delivering automatic temperature-controlled heating to protect eFlex and eFlex MAX battery performance when ambient temperatures drop below the optimal operating threshold.

Key Features:

• Self-Regulating Thermostat for Fully Automatic Cold Climate Protection: Simply set your desired activation temperature and the Heat Mat Kit powers on automatically when ambient temperatures drop, protecting battery performance year-round without manual intervention.
• 70W Silicone Heat Mat Adheres Directly to the eFlex Battery: The flexible silicone heat mat mounts directly onto the eFlex or eFlex MAX battery surface, delivering targeted, efficient heat exactly where it is needed for maximum thermal protection.
• DIN Rail AC Outlet for Clean, Integrated Installation Inside the DuraRack: The included DIN rail AC outlet mounts directly onto the DuraRack's factory-installed DIN rail, keeping all heating components neatly organized inside the enclosure without any external wiring.
• Supports Up to 14 Units in Parallel — 980W Total Heating Capacity: Multiple Heat Mat Kits can be connected in parallel across a multi-battery DuraRack installation, scaling heating capacity to match the number of batteries in the system.
• Complete Kit — Everything Included for a Full Installation: Ships with one DIN rail AC outlet, one silicone heat mat, one thermostat, and one heat mat cable — no additional accessories required for a complete cold climate heating setup.

The Fortress Power Heat Mat Kit is the definitive cold weather protection solution for any DuraRack or FlexTower battery installation exposed to freezing temperatures. Lithium iron phosphate batteries are sensitive to low temperatures during charging, and the Heat Mat Kit ensures that the eFlex and eFlex MAX units inside the DuraRack remain within their optimal operating range regardless of the outdoor ambient temperature.

Installation is clean and straightforward — the heat mat adheres directly to the battery surface, the thermostat and DIN rail AC outlet mount on the factory-installed DIN rail inside the DuraRack, and the included heat mat cable connects everything together. Once set to the desired activation temperature, the system operates fully automatically with zero ongoing maintenance or manual intervention required.

Whether installed in a cold northern climate, a high-altitude location, or any environment where winter temperatures regularly drop below 32°F, the Fortress Power Heat Mat Kit is the reliable, purpose-built solution that ensures battery health, longevity, and performance are never compromised by cold weather conditions.
