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.

2020年4月21日 · Thus, a BEC was a voltage regulator that would eliminate that second battery by providing regulated power for the receiver and servos directly from the main battery. The simplest BEC is a linear regulator (sometimes called LBEC ), a device that drops the voltage of its output by dropping the rest of the voltage on a variable resistor that would ...

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 …

2009年5月19日 · BEC stands for Battery Elimination Circuit and that is exactly what it is. What does a BEC do? Before lipos and advances in battery technology, the normal method of powering a receiver was through a seperate NiCd battery pack providing 4.8v to the receiver and servos.

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.

2023年7月5日 · It is produced in a BEC/UBEC adjustable to 8.4V ESC. If the ESC does not have BEC/UBEC function (such as photoelectric ESC produced for drones), the receiver and servo are powered by an external power supply. An independent BEC/UBEC circuit or a battery of appropriate voltage can be used as an external power source. What is ESC/ BEC/UBEC?

2024年1月30日 · Opto ESCs are lighter and cheaper, without any built-in voltage regulation. They're ideal for larger drones with a separate battery for powering on-board electronics. On the other hand, BEC (Battery Eliminator Circuit) ESCs are an all-in-one solution useful for smaller drones due to their integrated voltage regulation.

2017年7月25日 · A BEC, commonly called a UBEC (Universal Battery Eliminator Circuit), serves several functions. As others have stated, they act as voltage regulators, stepping voltage down to the appropriate level. Let's say that you are running …

2023年10月31日 · The BEC ESC is primarily used in radio-controlled cars, helicopters, drones, and boats to regulate motor speed and direction. At its core, a BEC ESC is an electronic device that efficiently converts the main battery’s higher voltage into a stable and regulated voltage suitable for powering the receiver, servo, and other onboard electronics.

2015年6月18日 · The BEC (battery elimination circuit) inside an esc allows the esc to power the Rx and/or FC, so depending on your flight controller, you may or may not need a BEC. If your FC is powered directly from the battery, you should not need a BEC.
