6 FAQs about [Relationship between the maximum current of the ESC and the battery]

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.

Do ESC batteries draw more current than ESC?

The batteries should be rated for the same or higher (continuous) current than the ESC, which should in turn be rated for a significantly higher current than the motor. The rule of thumb is: Never draw any more current than whatever you're drawing it from can supply. Also, motors can draw more current than they should.

Do ESCs limit current?

Some of the better ESC's do have current limiting, but experience in the flying field is that if you dork the thing into the dirt at full throttle, chances are that you'll damage the electronics due to overcurrent. An ESC could be designed to limit current in such a way (I've designed industrial motor controllers that do), but AFAIK ESC's don't.

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.

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.

What is the difference between battery voltage and ESC voltage?

1.Battery voltages should not be higher than the maximum voltage that ESC can suffer. 2.Continuously output of battery's current need to be bigger than the ESC's. Working voltage of the motor is decided by the ESC, whilst the voltage of ESC is decided by the output of batteries.
