ULANZI OA-16 Quick Release Vertical Shot Battery Door Cover for DJI Action3

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.

• 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.
