In battery-powered equipment, a battery eliminator circuit (BEC) is an electronic voltage regulator used to power a subsystem at a different voltage without the need for a supplemental battery. BECs are commonly used in radio-controlled models, which need separate voltages to power the motor and the RC equipment.

2015年6月15日 · What is a BEC? A Battery Elimination Circuit (BEC) is essentially a voltage regulator that steps down the voltage from the main LiPo battery pack (e.g., from 4S 14.8V or 6S 22.2V) to a lower voltage like 5V or 9V. Commonly integrated within the flight controller or ESC, the BEC eliminates the need for a separate battery to power your electronics.

The Battery Eliminator Circuit (BEC) plays a vital role in modern electronics by providing a stable and reliable power supply, thereby eliminating the need for multiple batteries.

2018年8月14日 · A battery eliminator circuit is a voltage regulator. It is designed to drop a big voltage down to a smaller voltage. As modern RC airplanes use high voltage batteries, it allows you to run your receiver, servos and other accessories from your main battery without using a seperate lower voltage one.

2012年7月24日 · In an electric-powered radio controlled model, the BEC is typically part of the electronic speed control (ESC). BEC allows such a model to carry only one battery (the motive power battery) instead of two (motive power, and a separate battery to …

A BEC is (usually) a switching voltage regulator that turns on and off very rapidly so as to allow only the necessary amount of energy through at a time. This allows for high efficiency BECs that can supply high amounts of power, and even have output voltages higher than the input voltages.

Such a regulator is called a “Battery Eliminator Circuit” or BEC, because it “eliminates” the need for a receiver battery. The term “BEC” is used only in RC. To the rest of the world, it is simply called a “voltage regulator.”
