Universal Battery Elimination Circuit (UBEC) $16.45

A UBEC can be an important accessory to an aerial drone. This Turnigy 5 to 7.5 Amp model is a nice choice. However, there are many different UBECs from different manufacturers and with different specifications. You’ll have to match this gift choice to the requirements of the drone it will be installed on.

A UBEC simply drops the supply voltage from the battery down to the 5 or 6V that is needed for the control electronics. Read on below for more about what a UBEC is and what it does.

What it Does

A UBEC provides isolated power for the control electronics like the receiver and servos. There’s probably already a small linear Battery Elimination Circuit (BEC) in the ESC. However, a UBEC has a more efficient switching power supply, resulting is less waste heat and longer battery life. It also ensures that even if the motors go dead, there is still power to the control electronics.

Why it’s Cool

OK. It’s not really very sexy or cool, but it does an important job. Plus, maybe you are looking for a less expensive gift to round out your purchases. Here it is!
