The ESC should always be rated to handle whatever current the motor draws at full throttle (100% PWM). You can lower the throttle to reduce battery current if necessary, but the motor current will then be higher - in inverse proportion to the PWM ratio. For example at half throttle (50% PWM) the motor current will be double the battery current.

6 Frequently Asked Questions about “How to match the battery with the ESC current”

How to choose an ESC battery?

Chose a battery with higher current rating than the peak current draw of the motor. The ESC can be selected based on the voltage and the peak current rating of the motor. A simple rule is to choose an ESC with atleast 5A more capacity than the peak rating of the motor, since you may be powering servos, receiver and other accessories from the ESC.

How does an ESC work?

An ESC can monitor current and have a current cutoff, but it delivers the same voltage for the same throttle imput regardless of the current flow that results. Also, the rated current of the motor, esc and battery do not necessarily reflect what you should actually run. The main factor is heat dissipation.

How to choose an ESC?

The ESC can be selected based on the voltage and the peak current rating of the motor. A simple rule is to choose an ESC with atleast 5A more capacity than the peak rating of the motor, since you may be powering servos, receiver and other accessories from the ESC. Remember to always round up.

How to match a brushless motor with an ESC?

Matching a brushless motor with the ESC is not that tough. For this, we will just need to identify the voltage rating of the motor we are using. After that, we will need to buy an ESC that can handle the sufficient current that we are planning to run. Just to understand, a motor can be rated as 6S and 50 amps maximum.

How to choose a motor ESC?

First, we must discover the motor's voltage rating. Then we need to get an ESC that can handle the current. It can be rated like a 6S motor with a 50 amp maximum. For this, the ESC must be rated at least 6S for this motor. Surpassing the ampere rating is wise. We prefer to give ESC headroom. That was only a glimpse of information.

How much current can a ESC handle?

Motor current is determined by voltage and loading. With good cooling Your motor should be able to handle ~15A continuous or 30A peak, which on 11.1V is achieved with a 5-6 inch propeller (test data here). Since your ESC is rated at 30A it should be safe so long as you don't overload the motor.
