Summary

GEPRC O4 Series Step-Down BEC is a dedicated regulated power module designed specifically for DJI O4 video transmission systems (including DJI O4 Air Unit and O4 Air Unit Pro).

It precisely matches the power requirements of the O4 system, efficiently stepping down voltage from 3–6S batteries while ensuring stable output. This eliminates issues such as video lag, unexpected rebooting, or black screens caused by unstable voltage, providing reliable power for FPV flights.

Feature

Dedicated for DJI O4 – plug and play

EN pad electronic switch control

Switchable 9V / 5V output — default 9V, short the 5V pad to switch

Wide input range: 10.5V–25.2V (3–6S)

Compact and lightweight design

Specifications

Product Name: GEPRC O4 Series Step-Down BEC

Dimensions: 17.0 × 8.3 mm

Input Voltage: DC 10.5–25.2V (3–6S Battery)

Output Voltage: 9V / 5V

Weight: 1g

Notes

This module only supports step-down conversion and does not provide boost functionality.

Input voltage must remain within the 6S battery range. Exceeding 25.2V will damage the module.

After shorting the 5V pad, the output is fixed at 5V. Do not repeatedly bridge/unbridge the pad to avoid voltage spikes that may damage the air unit.

Before flight, ensure all solder joints and wiring are secure, and verify the correct output voltage to prevent power interruption during flight.
