BEC Battery elimination circuit
The BEC is usually built into the Electronic Speed Controller (ESC), it eliminates the need for a separate battery to power the 5V electronic devices.
If you have ESC without the BEC you can use an external Battery elimination circuit
This brings us to UBEC
This is a separate component and is more efficient, more reliable than BEC as part of the Electronic Speed Controller
Why would a advertisement say "80A UBEC 2-6S ESC Electric Speed Controller" because Most BEC's are linear type, and UBEC are switching type
It comes down to the voltage regulator type
linear regulator (BEC) and switching voltage regulator (UBEC)
Linear type Highly inefficient and generates alot of heat, The primary reason people use them is because of the lack of radio frequency interference that is common in
the switching type regulator
Switching type very efficient almost 85% efficiency
The problem is this method emits loads of radio frequency interference and this causes unwanted issues with other electronic components
Video transmission problems for one, frequencies emitted by the switching voltage regulator interferes with the analog video signal and can reduce the range of the video.
Here is a picture of a seperate BEC setup This removes the power supplied from the ESC
