Drone, an unmanned aircraft piloted remotely or performing an autonomous flight.
They are powered by packages of lithium-ion or lithium-polymer batteries with voltages from 12 up to 22 V. The higher the voltage, the drone is faster and stronger. They can be equipped with 4 to 12 electric motors. Remotely controlled even from a distance of several kilometers, drones can rise to a height of several hundred meters.
The most advanced drones are capable of fully autonomous flights.
The most popular recreational drones are powered by lithium-ion packages with a capacity of approximately 1200 mAh and rated voltage of 11.4V (3S) allowing flight time up to 16 minutes.
Professional drones, used for film production or used by security services, are powered by up to six packages, each with a capacity of 4500 mAh and more, with a rated voltage of 22.2V (6S), allowing it to stay in the air up to 90 minutes, powering not only motors, but also a peripheral device like cameras, lamps or gimbals.
