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.
Electronic speed controls for model RC vehicles may incorporate a battery eliminator circuit to regulate voltage for the receiver, removing the need for separate receiver batteries. The regulator may be linear or switched mode. ESCs, in a broader sense, are PWM controllers for electric motors. The ESC generally accepts a nominal 50 Hz PWM servo ...
RC servos are usually powered by the receiver, which in turn is powered by battery packs or an electronic speed controller (ESC) with an integrated or a separate battery eliminator circuit (BEC). Common battery packs are either NiCd, NiMH or lithium-ion polymer battery (LiPo) type. Voltage ratings vary, but most receivers are operated at 5 V or ...

Philco Socket Power A & B Battery Eliminators - 1925 August brochure Philco Model B-60 "B" Socket Power Battery Eliminator - August 1925. Until the mid- to late-1920s, all radios except crystal sets were powered by vacuum tube batteries which were expensive, needed frequent charging, and leaked battery acid, reducing the wife approval factor in ...
An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
