Specifications：

  • Main Battery Input Voltage: 4-20S Lipo
  • Output Voltage: 5.0V (default) / 6.0V / 7.4V / 8.4V (4-10V adjustable by rotating calibration switch on the rear)
  • Output Current: Continuous 20A (duration time depends on external heat dissipation conditions)
  • Size: 60.4*47.15*28.2mm

Features：

  • Metal shielding cover for good heat dissipation and reducing electromagnetic interference. 
  • High efficiency DC-DC voltage regulator chip for transfer efficiency over 90%. 
  • Sustained output current up to 20A (depends on external heat dissipation conditions).
  • Main power input available 4-20S Lipo. Adjustable output voltage (4-10V) compatible with different voltages.
  • Various protections like over-current protection, output short circuit protection, overheating protection and low voltage cutoff.

Wiring Diagram：

If there is a built-in BEC in the brushless ESC, please disconnect the ESC's BEC output wires (e.g. “5V” and “GND” as shown below). Connect the signal wire “S” to the receiver's ‘S’ channel at the interface. Then, connect the UBEC's input wires in parallel with the battery pack. Plug the output terminals into the receiver's “+” and “-” channels

Voltage Output Adjustment：

Adjustable output voltage (4-10V) in four levels through the calibration switch on the rear. The factory default voltage is 5.0V, shown as below:

Front View: Rotating the potentiometer clockwise to reduce the output voltage; rotating it counterclockwise to increase the output voltage
