The Blackmagic Design Spares - Pocket Cinema Camera 4K (PCC4K) - Battery Door is the replacement hatch for the LP-E6 battery compartment. While it’s a relatively simple part, it is vital for ensuring that the battery remains securely seated and that the camera’s power circuit stays closed during operation.
Because the PCC4K is often handled roughly or mounted on tight gimbal plates, this door is one of the most frequently replaced external parts.
Kit Components
A standard replacement assembly typically includes:
-
The Main Door Panel: Made of the same carbon fiber reinforced polycarbonate as the camera body.
-
Metal Hinge Pin: The structural rod that anchors the door to the camera chassis.
-
Torsion Spring: The small wire spring that provides the "flip-open" tension when the latch is released.
-
Locking Latch: The sliding mechanism that clicks the door shut.
When to Replace the Battery Door
-
Snapped Hinge: The most common failure. If the camera is dropped with the door open, the plastic hinge loops or the metal pin can snap.
-
Broken Latch: If the sliding lock becomes loose or won't stay closed, the battery can slide out mid-shot, causing instant power loss and potential corruption of your BRAW or ProRes files.
-
Lost Spring: If the door flops around and doesn't spring open when unlocked, the internal torsion spring has likely snapped or fallen out.
-
Weather Sealing Issues: If the door is warped, it can allow dust or moisture into the battery well, potentially corroding the Battery PCB pins.
Technical Installation Note
Repair Level: 1 (Easy). This is a "no-tools" or "minimal-tools" repair that can be done in the field.
-
Pin Removal: On the bottom of the camera, near the hinge, there is a small access point for the hinge pin. You may need a small jeweler's screwdriver or a sturdy pin to slide the metal rod out of the hinge.
-
Spring Orientation: This is the trickiest part. The torsion spring must be oriented so that one "leg" rests against the door and the other against the camera body.
-
Alignment: Slide the pin through the first hinge loop of the camera body, through the spring, through the door, and finally into the second hinge loop of the body.
-
Testing: Once the pin is seated, the door should "snap" open when the latch is released. If it feels mushy, the spring is likely installed backward.
Pro-Tip for Gimbal Users
If you frequently use a DJI RS series or Zhiyun gimbal, you may notice that some quick-release plates block the battery door from opening. To avoid snapping the door off:
-
Ensure your plate is offset to the left side of the camera.
-
If the plate is too wide, consider using a Half Cage or a dedicated PCC4K Baseplate that includes a "cutout" for the battery door swing radius.
Is your door physically broken at the hinge, or is the sliding latch simply failing to stay closed?
