When we use drones, we will find that the battery life is not long, about half an hour. For agricultural drones, the battery life is even shorter. Why are the flight times of these drones so short? Here drones refer to our commonly used civilian or consumer drones. First of all, most drones are mainly powered by lithium batteries to power the motors to achieve the purpose of driving. The larger the battery capacity and the more power it provides, the longer the flight time will be. However, in this case, it is often necessary to increase the size of the battery. As a result, the weight of the battery will also increase, which will also have a certain impact on the flight of the drone. In fact, the drone will be affected by many factors during the flight. The power of the ESC and the motor will affect the battery discharge. For example, the greater the discharge current of the battery, the lower the output capacity. If you want to increase the endurance of drones, the requirements for lithium batteries will become higher and higher. The current level of technology basically allows the drone to maintain a flight time of about 20 minutes. If you want to extend the flight time to more than a few hours, it is basically impossible to rely on battery functions.
