Building Smart Drones with ESP8266 and Arduino

Battery

A drone is useless without a battery. All motors, flight controllers, radio, and processing require power. But it is not a wise decision to use the heavy battery to fly your drone because most of the energy will be spent on the thrust of a drone to fly. So, we need to choose light but powerful batteries. In a drone, we usually use lithium polymer batteries.

Choosing the right battery for the drone is one of the most critical things. Before choosing batteries for your drone, keep the following things in mind:

• Battery size and weight
• Battery discharge rate
• Battery capacity
• Battery voltage
• Battery connectors

You can easily calculate the continuous current output of the battery with the help of the following formula. If the current ...
