MAYRC Convert 75V Voltage to 12V 2.5A Voltage Regulator UBEC Module for MTVESC6.12 Speed Controller

What is UBEC and What does UBEC do?

UBEC stands for universal BEC or sometimes ultimate BEC. It’s used when ESC doesn’t have built-in BEC, or standalone power system is required. They generally are more efficient, more reliable and able to provide more current than BEC. The UBEC is connected directly to the main battery of the multicopter, the same way as an ESC.
