Voltage & Current (V & A)

Voltage is an electromotive force or potential difference expressed in volts. Current is a flow of electric charge, carried by moving electrons in a wire. These are two figures that you will find on every battery. Each plays a role in outputting power through your electronics, and they are crucial to understand in order to properly design your board.

Most electronic components such as ESCs, motors, BMSs and batteries will have safe operating voltages and amperage ratings. Generally you shouldn't operate near these limits, because your components will get hot and potentially damaged.
