Drones

Lithium batteries are crucial in the drone industry, primarily in the following aspects:

Power Supply

Provides power to the drone's motors, enabling takeoff, hovering, flight, and various maneuvers. Lithium batteries have high energy density, storing significant electrical energy in a relatively small volume and weight, providing sufficient power support for drones and ensuring flight endurance. For example, the DJI Mavic 4 Pro drone's intelligent flight battery, with a capacity of 5870mAh and voltage of 15.2V, provides approximately 30 minutes of flight time.

Device Operation

Powers other electronic devices on the drone, such as the flight control system, sensors (including GPS modules, cameras, obstacle avoidance sensors, etc.), and communication modules. These devices are crucial for stable flight, navigation, shooting, and data transmission, and lithium batteries provide stable voltage and current output to ensure their proper operation. For example, the DJI Mavic 3's built-in lithium battery powers not only the motors but also its professional Hasselblad camera and a series of advanced flight assistance sensors, ensuring high-quality photos and videos during flight, while achieving precise flight control and safe obstacle avoidance.

Energy Recovery and Management

Some high-end drones have energy recovery systems. During drone flight, when the motors are braking or descending, some kinetic energy can be converted into electrical energy and stored back into the lithium battery, improving energy efficiency and increasing flight range. In addition, the Battery Management System (BMS) monitors the battery's status in real-time, including voltage, current, and temperature parameters, preventing overcharging, over-discharging, and overheating, ensuring safe battery use and extending its lifespan. For example, DJI's intelligent flight batteries are equipped with an advanced BMS for precise power management and safety protection, supporting battery power balancing to improve the performance and lifespan of the entire battery pack.
