CSi PTC heaters maintain battery charge and prevents irreversible battery damage due to extreme low temperatures, thus extending battery life and mission duration.

Problem: As temperatures drop battery capacity begins to degrade rapidly, resulting in significantly diminshed mission durations, temporary usability issues and even irreversible damage.

Solution: CSi heaters and controllers maintain internal battery temperatures well within operating range, thus extending battery duration. Our heater and controller can be adapted to fit many existing batteries and other products used in cold operations.

One of the drones that we had was supposed to have about 20 minutes of flight time. But, in the cold we got four to five minutes. . . Either you carry a lot more batteries, which are heavy, or we figure out better ways to get more out of . . . the batteries that we will have.
