What does a battery eliminator circuit do?

A battery eliminator circuit (BEC) is an electronic circuit designed to deliver electrical power to other circuitry without the need for multiple batteries. Historically the expression was sometimes used to describe devices used to power battery-driven equipment from mains electricity.

What is the purpose of a BEC in RC?

A BEC (Battery Eliminator Circuit) is a device that allows your servo to get the juice it needs from the receiver by way of a direct connection to the battery. This allows for a powerful servo to operate at full capacity without causing your system (and by proxy, your vehicle) to go haywire.

What is a BEC kit on a RC?

CC BEC (Battery Eliminator Circuit) is a small device that eliminates the need for a receiver battery. It draws voltage from the motor batteries and drops it to a voltage level that is suitable for your receiver and servos.

Do I need a BEC for my receiver?

Like most mini receivers, the Traxxas 2.4GHz receiver is not equipped with a BEC. Whatever voltage your receiver battery or speed control puts into the receiver is what the receiver will deliver to the servos.

What is the difference between battery and battery eliminator?

A battery eliminator is a device powered by an electrical source other than a battery, which then converts the source to a suitable DC voltage that may be used by a second device designed to be powered by batteries. A solar panel providing power for a portable appliance may also be considered a battery eliminator.

Do I need a BEC?

Unless the servo draws a huge amount of current, an external BEC is not needed. IF the ESC does not have a built in BEC, then one should be wired from the battery into the battery port on the RX powering both the ESC and servo as well as the RX.

Is a BEC necessary?

Do I need external BEC?

amps are what the bec needs to supply if the esc can’t supply more than 1-3 like typical, you need a bec to supply 5-10 amps. Of course if you just bash around you won’t need to worry about a bec, although you are underpowering your steering servo.

Do you need an external battery eliminator circuit?

We carry several external Battery Eliminator Circuits (BECs) for use in RC Airplanes and RC helicopters. You may want to consider using an external BEC if you have an aircraft with a lot of servos, or the ESC you have chosen does not have an internal BEC. Popular brands include ZTW, and Castle Creations.

What does a Traxxas battery eliminator circuit do?

A Traxxas BEC is a battery eliminator circuit. The BEC allows a single battery to send less power to multiple parts of the RC car. Without the BEC there would have to be many different batteries for each small part of the vehicle.

What do you call a battery elimination circuit?

Electric Modelers will refer to this unit as a BEC unit as this is the name given by many ESC manufcatures. These names will be used interchangeably throughout this article. One of the most commonly used accessory for the radio system in RC is the BEC (Battery Elimination Circuit) unit or Voltage Regular.

Can a RC car be powered without a BEC?

Without the BEC there would have to be many different batteries for each small part of the vehicle. Instead, since the BEC is there then the RC car can have one larger battery. The BEC makes the right amount of power go to each part and in turn can power the entire RC car off a single battery.
