The Hobbywing UBEC 25A HV is a professional-grade external switching BEC designed for large RC helicopters, fixed-wing aircraft, UAVs and high-performance models requiring reliable high-current power delivery. Supporting an ultra-wide 3-18S LiPo input range, it converts battery voltage into a stable output for receivers, flight controllers, servos and onboard electronics.

With selectable output voltages of 5.2V, 6.0V, 7.4V and 8.4V, the UBEC delivers up to 25A continuous current and 50A peak current, making it ideal for multiple high-torque HV servos. Advanced DC-DC switching technology provides over 90% efficiency while reducing heat generation and power loss.

The integrated backup battery input allows a secondary 1-2S LiPo battery to automatically take over if the primary power source fails, providing additional safety for valuable aircraft. Housed in a durable aluminium case, the UBEC also features over-current, short-circuit, thermal and low-voltage protection for dependable operation in demanding environments.
