Looking for 25a Servo? Hobbywing Servo UBEC 25A HV is available at Zbotic with fast shipping across India.
The UBEC is an external switching-mode DC-DC regulator chip. It draws the DC voltage from a 3-18S LiPo battery and drops the voltage to a level suitable for receivers and other electronic devices and keeps providing the stable current output of up to 25Amp. The UBEC has such a powerful output capability, so it is particularly applicable for the large helicopters or fixed-wing aircraft which use several servos.
Features:
- High efficiency DC-DC regulator chip for transfer efficiency of over 90%.
- Adjustable output voltage (5.2V/6.0V/7.4V/8.4V) applicable for servos with different voltages.
- 8-channel parallel outputs for greater current endurance.
- BEC shoot-through protection prevents the input voltage of the main power supply from directly flowing to the output end of the UBEC and damaging the electronic devices connecting to
the output end when the UBEC is accidentally damaged. - Multiple protections including over-current, (output end) short circuit, overheat, and low-voltage cutoff.
- Backup power supply connecting function allows the connected electronic devices to directly get power from the backup power supply to keep the normal operation when the main power
supply connecting to the UBEC is damaged or the UBEC fails. - External switch allows to turn on/off the UBEC easily.
- Metal housing for quick heat dissipation and less electromagnetic interference.
- LED indicator for indicating the work status of the UBEC and the connecting status of the backup power supply.
- Backup Input Voltage 1-2S LiPo
- Output Amperage Continuous Current: 25A

Hobbywing Servo UBEC 25A HV Overview
The Hobbywing Servo UBEC 25A HV is a high-current external switching DC-DC regulator designed to supply stable power for receivers and servos in large-scale RC models. Capable of handling 3–18S LiPo as its main input and delivering up to 25 A continuous (50 A peak), it ensures reliable voltage regulation for multi-servo setups.
Key Features of Hobbywing Servo UBEC 25A HV
- Wide main input range: supports 3–18S LiPo batteries for helicopters, planes, and drones
- Backup input: accepts 1–2S LiPo to maintain power if primary supply drops
- Adjustable output voltages: 5.2 V, 6.0 V, 7.4 V or 8.4 V selectable to match servo requirements
- High efficiency DC-DC regulator chip with over 90% transfer efficiency
- Continuous current 25 A, peak current 50 A for heavy-duty servo loads
- 8-channel parallel outputs for distributing power across multiple servos
- Available with genuine Hobbywing quality and fast shipping from Zbotic
Applications and Use Cases
- Large-scale RC helicopters running multiple high-torque servos
- Fixed-wing aircraft requiring consistent voltage for flaps, rudders, and ailerons
- Multi-rotor drones with heavy gimbal servos for stabilized camera mounts
- Advanced robotics projects needing a reliable 25 A power source
- Scale models or industrial prototypes with synchronized servo arrays
How to Use Hobbywing Servo UBEC 25A HV
Mount the UBEC close to your main battery connection and wire the main input to your 3–18S LiPo lead, then optionally connect a 1–2S LiPo to the backup input. Select the desired output voltage via the onboard switch, plug your receiver and servo leads into the parallel outputs, and secure all connections. Power up the system and verify stable voltage under servo load.

Frequently Asked Questions
Can I use the UBEC 25A HV with a 6S LiPo pack?
Yes. The main input supports 3–18S LiPo, so a 6S pack is within range. Ensure correct polarity and secure connections before powering up.
How do I change the output voltage on this UBEC?
A small slide switch on the side allows you to select between 5.2 V, 6.0 V, 7.4 V, and 8.4 V. Always switch voltages with the unit powered off, then reconnect power.
Will this UBEC handle powering four digital servos at once?
Yes. With a continuous output of 25 A and 8-channel parallel outputs, it can sustain multiple servos simultaneously without voltage drop, provided total current draw stays within limits.
