How to choose the suitable ESC for DIY drone

Electronic governor (referred to as ESC, ESC) function is equivalent to the throttle of the drone. It can send commands to the motors through the logic board. The electronic governor converts the signal from the lithium polymer battery into an alternating square wave. Generally speaking, brushless motors are three-phase, and the instantaneous value of each phase changes. There are high potentials, low potentials and intermediate potentials at any one time. It can send commands to the motors through the logic board. The electronic governor converts the signal from the lithium polymer battery into an alternating square wave. below is tell you how to choose the suitable ESC for DIY drone

1. Current

Generally XAXXA marked on the ESC, as the picture shows 120 A refers to the current, usually the value marked on the ESC refers to the continuous output current of the ESC. In addition to this current parameter, some ESCs will also mark the instantaneous current on the manual or parameter table.

2. xS-xS LiPo

This 2-6S of characters on the ESC indicates how big the battery can be and the type of battery, which is also equivalent to telling the voltage range supported by the ESC from the side.
