BEC’s - Battery Eliminator Circuits
A battery eliminator circuit (BEC) is a device used in radio-controlled (RC) models to power the electronics of the model, such as the receiver, servos, and control surfaces, without the need for a separate battery pack. It does this by taking power from the main battery pack that is used to power the motors and then regulating and distributing it to the electronics.
One of the main benefits of using a BEC is that it allows the user to save weight and space by eliminating the need for a separate battery pack for the electronics. This can be especially useful in RC models with limited space, such as small drones or racing cars. Additionally, a BEC can help to simplify the wiring setup of the model by reducing the number of battery connections and cables required.
BECs are typically used in conjunction with brushless electronic speed controllers (ESCs) in RC models, and are often built into the ESC itself. They are available in a range of current ratings to suit different power requirements, and can be used with either lithium polymer (LiPo) or nickel metal hydride (NiMH) battery packs.
Overall, a BEC is an important and useful device in the world of RC modeling, as it allows the user to power the electronics of the model efficiently and conveniently while saving weight and space.
