What is BEC?
BEC stands for Battery Eliminator Circuit.
In Radio Control (RC) contexts, the BEC is extra circuitry on the ESC (Electronic Speed Controller ie. Motor Controller) to provide power to the controls (such as steering, servos, receivers) to the controlled vehicle (eg. airplane, car, helicopter, boat) so that this control circuitry does not need to carry it’s own battery pack. That is, it piggy backs of the battery pack used to drive the motors of the vehicle or in other words, the motor and servos share the same battery pack.
In motorcycle / ATV contexts (which use Internal Combustion Engines), BECs are sometimes used so that a battery is not required. Instead, it relies on the alternator to generate the required electricity and the BEC is used to regulate the electrical power which will be used for electrical items on the motorcycle / ATV such as lights, horn etc. If there is no battery, there is no electric starter on these machines.
What is UBEC?
UBEC stands for Ultimate Battery Eliminator Circuit. In RC (Radio Control) contexts, a UBEC is an improved version of a BEC. ESCs with a UBEC use circuitry that is more efficient than a ESC with a BEC, thus you save battery power. Also, ESCs with UBECs tend to run co/oler than ESCs with BECs.
