The difference between ESC with BEC and without BEC

Posted by Fengyukun on

This article explains the difference between ESCs with BEC and without BEC
What is BEC?
BEC: Power module, used to power servos or receivers. The BEC voltage of general ESCs is 5v, 7v, 12v, and the current is 1a, 2a, etc.

(Power supply module)
ESCs with BEC power module: This type of ESC has a built-in BEC module, and does not require an external BEC. It can directly obtain power from the battery and power the receiver and other control devices through the BEC module without an additional power connection.

ESCs without BEC power module: This type of ESC needs to be wired by itself, or an adapter cable is required. Use an external BEC and adapter cable to connect to ESCs, thrusters, receivers, power supplies and other equipment before use.

The presence or absence of BEC does not affect the use of the ESC, nor does it affect the performance or function of the ESC.

Take two ESCs of our company as an example:

1. 45a ESC (without BEC), with only two signal wires and no wire in the middle.

2. 30a ESC (with BEC, 5v, 1a), with three signal wires and a thin red wire in the middle, which is the positive pole (5v output).

Ps: Please check the parameters in detail when purchasing, or ask our customer service staff.
