3.4. Don’t worry about the polarity of battery pack. If the polarity is not correct, the UBEC can’t
work, but it will not be destroyed. What you need to do is just swap the battery pack polarity.
3.5. A shield covers almost all the electronic components on PCB, and a ferrite ring is attached
with the output wires to decrease the electromagnetic interference.
4. How to use UBEC?
4.1. Important hint: Switch mode UBEC may cause some electromagnetic interference
to receiver, Please install the UBEC with a distance at least 5cm away from the receiver.
4.2. When ESC HAS NOT built-in BEC function
No change is needed for the ESC, just connect the input cables of UBEC with the battery, and
plug the output cable (connector) of the UBEC into one spare channel of the receiver.
4.3. When ESC HAS built-in BEC function
You must disable the built-in BEC function of the ESC, i.e. you need to cut the red wire in the
trio of receiver wires. Simply use a pair of wire cutters to remove a short section of the red wire
near the receiver connector, and insulate the cut wire with a bit of electrical tape.
Suggestion:
You can use a sharp screwdriver to take the pin (with red wire) out from the BEC
connector of the ESC, and then insulate it with a bit of electrical tape for further use, so you
needn’t cut the red wire by this method.
