Description
Hobbywing HV 25A UBEC offers elegance, power, extended protection features, and simplicity all in a compact solution. Housed inside of an aluminum case, the UBEC is able to dissipate more head 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, 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, includes an external switch to power on and off the unit, and output voltage is adjustable from 5v, 6v, 7.4v, and 8.4v. 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 when the UBEC is accidentally damaged, plus the protections like over-current, (output end) short-circuit, overheat, low-voltage cutoff guarantee safety and reliability.
Additionally, the UBEC features the ability to connect to a separate 2s LiPo providing backup in the event that the main power fails.

Rodney Sherburne Verified Owner Sunday, Mar 2 2025 (7 months ago) Hobbywing 25 Amp HV UBEC Slick little unit , But way over rated in amp handling ability!
The circuit board can no way handle 50 amps even for a second and the 25 amps is maybe of a duty cycle of 5%. Yes thats 5 min of available use in a hour.
I understand that your not cycling all 8 servos at the same time but still very weak in amps.
Then they say you can tie all the positives and negatives together to get a single high amp output. Ahh NOT ! Ive bench tested many times and you might get 10 to 15 amps if your lucky.
Bottom line is if your only using a few low amp servos at a time them maybe it will work ok for ya View all reviews
