Product Description

⚠️ NOT Waterproof

  • The ULANZI OA-16 magnetic battery door is NOT waterproof. Do NOT use this door for any activity where the camera may be exposed to water, rain, splashes, or submersion. Switch back to your original DJI waterproof door before any water-based activity.

The ULANZI OA-16 Quick Release Vertical Shot Battery Door Cover for DJI Action3 is the tool-free magnetic door replacement that unlocks vertical shooting mode and full magnetic accessory compatibility on your DJI Osmo Action3 — snapping into place in seconds with a satisfying click, no tools or screws required.

The original DJI Action3 battery door is replaced with this aluminium magnetic door, which adds a magnetic base to the side of the camera. This allows you to instantly switch between horizontal and vertical orientations and connect a range of magnetic accessories — including the separately available ULANZI OA-19 shoe mount. The quick release mechanism means swapping back to your original waterproof door for water activities takes seconds.

Key Features:

  • Magnetic Battery Door Replacement: Replaces the original DJI Action3 battery door with a magnetic aluminium door — tool-free installation, clicks securely into place in seconds.
  • Vertical Shot Mode: The magnetic base on the door enables instant switching between horizontal and vertical orientations — ideal for social media content, reels, and portrait-format shooting.
  • Magnetic Accessory Compatibility: Opens up the DJI magnetic accessory ecosystem — connect magnetic mounts, the ULANZI OA-19 shoe mount (sold separately), and other compatible magnetic accessories directly to the side of the camera.
  • Quick Release Mechanism: Fast, tool-free installation and removal — swap back to your original waterproof door before water activities in seconds.
  • Durable Aluminium Construction: Lightweight yet rigid aluminium alloy door — a solid, rattle-free fit that matches the build quality of the DJI Action3.
  • DJI Action3 ONLY: Precision-engineered specifically for the DJI Osmo Action3. NOT compatible with DJI Action4, DJI Action5 Pro, or any other model.
