Currently, lithium-ion batteries are widely used as power sources for drones. However, the performance of these batteries can fluctuate significantly with temperature changes. The relationship between battery performance and temperature is roughly illustrated in the figure below:
Experienced drone operators might recall that during cold weather, drone batteries tend to lose power rapidly, leading to shorter flight times. This makes proper winter battery maintenance especially crucial.
To ensure a smooth flying experience in the winter, we’ve put together some essential tips for DOBBY users. Let’s dive into what you need to know when flying your drone in cold conditions.
Winter Flying Tips for DOBBY
Pre-Flight Preparation
Plan your flight route and shooting strategy on the ground before takeoff. This helps avoid last-minute decisions in the air.
Charge the battery fully before flying to ensure it's at a high voltage level. A well-charged battery performs better in low temperatures.
Store the battery in a warm pocket or inside your clothing before takeoff to protect it from the cold. Make sure the battery temperature is above 15°C before use.
During Flight
Take off as soon as the drone is ready to minimize exposure to cold temperatures.
Once airborne, let the drone hover for about 15 seconds. This allows the battery to warm up internally, reducing internal resistance and improving performance.
Avoid long-distance flights and always keep extra power for the return journey. Monitor the battery level closely and return immediately if a low voltage warning appears.
Battery Storage and Maintenance
Proper storage is key to maintaining battery health:
- Recommended storage temperature: 10°C - 25°C
- Operating temperature range: 0°C - 45°C. If using in 0°C conditions, preheat the battery to at least 15°C before flight.
- Do not leave fully charged batteries for more than three days. Long-term full charge reduces battery life. Charge the battery just before use.
- If not planning to use the battery for an extended period, discharge it to 60%-80% before storing. If no professional equipment is available, you can monitor the battery level on the screen to achieve this. Repeat this process every three months if stored for longer than that.
- Store batteries in a dry, non-corrosive environment. For long-term storage, place them in a sealed bag or explosion-proof container.
Following these guidelines will help extend the life of your drone’s battery and ensure safe and enjoyable flights, even in colder weather. Mastering these techniques can make a big difference in your winter flying experience. Remember, if you're in a particularly cold region, extra care is needed before each flight. Have a great time flying your DOBBY!

Catering to the ever-changing demands of our patrons, we are offering them a comprehensive range of Hot Dip Galvanized Radiator. These are manufactured as per latest market trends so as to ensure their wide applications in industries. Offered products are highly demanded by the clients for their excellent design, longer service life and durability.
Galvanizing is a way of defending a steel surface from corrosion by delivering a surface coat of Zinc. The process is carried out by dipping the radiator in molten zinc bath which is upheld at a temperature of about 450 degrees.
In long-term, continuous exposure, the recommended maximum temperature for hot-dip galvanized steel is 200 °C (392 °F), according to the American Galvanizers Association. The use of galvanized steel at temperatures above this will result in peeling of the zinc at the inter metallic layer.Hdg Radiator,Oil-Immersed Hdg Radiator,Hot-Dip Galvanizing Radiator,High-Performance Hot Dip Galvanized Radiator
