9.6V 4A Switching UBEC Regulator
The FingerTech 9.6V 4A UBEC is a compact switching regulator that supplies a stable 9.6V to power 9V-rated servos from any 3S–6S LiPo. If you’re running a FingerTech 9V digital servo on a higher-voltage battery, this UBEC steps the voltage down to the servo’s optimal operating range. Not for receiver power — use the 5V 4A UBEC for that. Sold individually.

FingerTech 9.6V 4A UBEC
The FingerTech 9.6V 4A UBEC is a compact switching regulator that steps down any 3S–6S LiPo to a stable 9.6V at up to 4A — purpose-matched for 9V-rated servos like the FingerTech 9V digital servo. If you’re running a higher-voltage battery for your drive system but need regulated 9V for your servo, this UBEC fills that gap. This UBEC is for 9V-rated servos only — do not use it for receiver power or standard 4.8–6.8V servos. For receiver power, use the FingerTech 5V 4A UBEC instead.
Switching Regulator — Not Linear
This is a switching regulator, not a linear one. Linear regulators burn off excess voltage as heat — inefficient and bulky. This UBEC converts the excess efficiently, running cooler and drawing less from your battery. At 6.3g it adds almost nothing to your build, and 4A of output is enough to run up to three FH-5515MG metal gear servos simultaneously.
Wiring It Up
- UBEC Input: Connect the UBEC’s input wires (IN+ and IN−) to your battery after your power switch.
- Servo Power Wire: Pull the servo’s center red wire out of its connector and connect it to the UBEC’s OUT+ wire.
- Servo Signal Wire: Plug the servo’s signal wire (white or orange) into the appropriate receiver channel.
- Ground Connections: Connect the UBEC’s ground wire (black) to one of the receiver’s ground terminals. Ensure the servo’s ground wire (black or brown) is also connected to the receiver’s ground terminal.
- Receiver Power: Your receiver still needs a separate 5V supply — use the FingerTech 5V UBEC or ensure your ESCs supply a 5V return line.
Your drive motors run at full battery voltage, the receiver gets its 5V, and the servo runs at its optimal 9V. Use terminal blocks to keep multiple connections clean.

Sold individually. Includes a 20cm (7.9in) servo wire.

Frequently Asked Questions
What is a UBEC?
UBEC stands for Universal Battery Elimination Circuit. It's a switching voltage regulator that takes in your full battery voltage and outputs a clean, stable lower voltage to power servos or receivers. This one outputs 9.6V, matched to the operating voltage of FingerTech's 9V-rated servo line.
When do I need this UBEC?
You need this UBEC when you're running a 9V-rated servo — like the FingerTech 9V digital servo — on a 3S or higher battery. Without it, the servo receives full battery voltage, which will damage it. Standard servos rated 4.8–6.8V do not need this UBEC.
Can I use this to power my receiver?
No — this UBEC outputs 9.6V, which will damage a standard receiver. Receivers operate at 4.5–6.5V. Use the FingerTech 5V 4A UBEC for receiver power.
Does my receiver still need a separate 5V supply?
Yes — this UBEC powers your servo only. Your receiver needs its own 5V source, either from an ESC with a built-in BEC or a dedicated 5V UBEC.
How do I wire it up?
Connect the UBEC's IN+/− wires to your battery after your power switch. Pull the servo's center red wire from its connector and connect it to the UBEC's OUT+ wire. Plug the servo's signal wire into your receiver channel. Connect the UBEC's ground wire to one of the receiver's ground terminals. See the wiring diagram in the Description tab for a visual reference.
Which FingerTech servos work with this UBEC?
This UBEC is matched to FingerTech's 9V-rated servo line, including the FingerTech 25kg 9V Digital Servo and the FH-5515MG analog metal gear servo. If your servo is not rated for 9V operation, do not use this UBEC.
