The Hobbywing HV 25A UBEC offers elegance, power, extended protection features, and simplicity all in a compact solution. Housed inside of an aluminium case, the UBEC is able to dissipate more heat and reduce electromagnetic interference. A high efficiency DC-DC regulator paired with special designed circuitry offers conversion efficiency over 90%. Capable of 25A continuous current (w/ peak current of up to 50A), the UBEC is the ideal choice for even the most demanding of applications.

The UBEC accepts a wide input voltage ranging from 3s (11.1V) to 18s (66.6v). Its output voltage is adjustable in four steps including 5v, 6v, 7.4v, and 8.4v. It also includes an external switch to power on and off the unit.

It has a number of safety features to guarantee safety and reliability, including UBEC shoot-through protection, which prevents the voltage of the main power supply from directly flowing to the output end of the UBEC and causing any damage to the connected electronic device, in the event that the UBEC is accidentally damaged; plus others protections like over-current (output end), short-circuit, overheat, and low-voltage cut-off.

For optimal power security, the UBEC features the ability to connect an additional external backup battery. This one automatically takes over if the main battery is empty or defective.
