DJI Matrice 4 Series Battery

The Cellular Dongle 2 is a compact 4G module engineered to maintain uninterrupted drone control and live video feed when the primary O4 transmission signal degrades or is blocked. Featuring Antenna Switch Diversity (ASDIV), it automatically switches to mobile networks to reduce the risk of disconnection during flight, significantly improving transmission reliability.

It supports Enhanced Transmission: a free one‑year service included at purchase, enabling seamless switching to 4G for command and video links if the radio link fails. Designed for easy integration, it slides directly into compatible aircraft like the Air 3 and Air 3 S—no extra mounting kit required—while some models (Mini 4 Pro) need an antenna kit.

Compatibility extends across models such as DJI’s Matrice 4 series and Dock 2, offering a flexible solution for various applications. This dongle offers intelligent failover for video and control, secure data encryption, and improved flight safety, making it ideal for long-range or obstacle-filled environments
