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 · Many of the product pages include terms related to a BEC, such as SBEC, UBEC, and Opto. What do those acronyms mean and how should I choose between them when selecting an ESC?

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 · 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 …

2024年1月30日 · Get a comprehensive understanding of how RC drone components work together with this informative guide. Learn about motors, ESCs, and flight controllers in detail.

2015年10月2日 · Technically, BEC stands for Battery Eliminating Circuit. In practice, this simply means that ESCs with a BEC are able to output a constant voltage and so power the equipment on board your flying platform, such as your receiver, servos or flight controller.

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.

2024年4月16日 · A Battery Eliminator Circuit (BEC) is a power supply in Electronic speed controllers (ESCs) that supplies other devices in the Drone. For example servo motors, radar…
