Fortress Heat Mat Kit Keeps DuraRack Batteries Warm in Winter
Lithium batteries should not charge below freezing, and the DuraRack does not include a heater. The Fortress Power Heat Mat Kit solves that. It pairs peel-and-stick silicone heat mats with a thermostat controller and a DIN-rail AC outlet, so the mats switch on automatically to keep eFlex batteries at a safe temperature. Fortress recommends setting the thermostat to 40°F.
Why You'll Love The Fortress Heat Mat Kit
Charge through cold snaps. Keeps batteries warm enough to accept charge on freezing days.
Automatic control. The thermostat turns the mats on and off around your set point, adjustable from 40 to 108°F.
Peel and stick. Silicone mats with 3 mm adhesive stick straight to the back of each battery.
Expandable. Up to 14 mats (980W) can run in parallel from one thermostat.
Your life, with the Fortress Heat Mat Kit
A cold front drops the garage below freezing overnight. In the morning your batteries are still warm, the sun comes up and they start charging right away instead of waiting for the afternoon.
