The use of LiPo batteries in drones is due to their high discharge rates, which are necessary to power the motors and other components of the drone. The battery is usually housed in the drone’s body and is connected to the flight controller, which regulates the power distribution to the different components of the drone.
How Drone Batteries Work
Drone batteries work on the principle of electrochemical reactions. The LiPo cells in the battery contain three main components: a positive electrode (cathode), a negative electrode (anode), and an electrolyte. When the battery is connected to a circuit, a chemical reaction occurs between the electrodes and the electrolyte, resulting in the flow of electrons and thus electricity. The capacity of the battery is measured in milliampere-hours (mAh), which represents the total amount of energy that the battery can store.
