Features: Adopting intelligent battery technology, which ensures real-time acquisition of current remaining battery level and calculation of the remaining flight time during the flight process. When the battery is not used for long time, the battery will automatically discharge to 50%, keeping the battery in its best state and prolonging its service life. If you flying in cold regions, will activate low-temperature protections and control power output base on temperature, ensuring that the battery is power at the appropriate temperature to protect it from low-temperature damage. Intelligent battery technology can not only monitor battery status and extend service life, but more importantly, provide safe and reliable battery monitoring to make flight safe. With unctions such as overcharge and over discharge protections, idle protections, and low temperature protections.
