The Blackmagic Design Spares - Camera PCC6K - PCB Battery is the internal power interface board for the original Pocket Cinema Camera 6K (EF mount). This specific board acts as the mounting point and electronic regulator for the LP-E6 battery system.
While the "Power Assembly Cable" is the wiring that moves the electricity, the Battery PCB is the rigid board that contains the physical contact pins and the "handshake" logic for the battery.
Functional Role
The Battery PCB is the primary gateway for portable power in the 6K:
-
Terminal Contact: Houses the spring-loaded metal pins that interface with the terminals of an LP-E6 or LP-E6N battery.
-
Voltage Regulation: Filters the raw battery voltage to ensure it is clean and stable before it reaches the sensitive Main PCB.
-
Battery Identification: Contains the circuitry that allows the camera to read the battery's internal chip, providing the "percentage" or "voltage" readout on the top-right of your LCD.
-
Power Switching: Works in conjunction with the DC input to handle the "seamless switch" from battery to AC power when the camera is plugged in.
When to Replace the Battery PCB
This board is prone to physical wear and environmental damage because it is located inside the battery compartment:
-
Bent or Broken Pins: If a battery was forced in backwards or a foreign object entered the compartment, the pins can snap. These are soldered directly to this PCB, so the whole board is typically replaced.
-
Corrosion from Leaky Batteries: If a low-quality third-party battery leaks or "vents" inside the camera, the chemicals will eat through the traces on this PCB first.
-
"No Battery" Error: If the camera works on DC power but shows a "cross" over the battery icon even with a known-good LP-E6, the logic chip on this board has likely failed.
-
Thermal Damage: High-frame-rate recording generates heat. If the battery compartment gets excessively hot, the solder joints on the battery terminals can become "cold" or brittle, leading to intermittent power loss.
Key Features
-
Genuine OEM Part: Designed specifically for the LP-E6 voltage range ($7.2\text{V}$ to $8.4\text{V}$).
-
Low Resistance: High-quality gold-plated contacts to prevent power loss and heat buildup during long takes.
-
Direct Fit: Screws directly into the chassis standoffs located behind the battery door.
Technical Installation Note
Replacing the Battery PCB is a Level 2 repair, requiring you to open the camera's rear shell.
-
Access: You must remove the back panel of the camera. Be extremely cautious of the fixed LCD ribbon cable—it is very short and can tear if the back panel is pulled away too quickly.
-
Cable Seating: This board connects to the Power Assembly Cable via a small multi-pin connector. Ensure this is fully "clicked" in; if it’s loose, the camera might turn on but fail to show the battery percentage.
-
Alignment: When screwing the PCB back in, ensure the pins are perfectly centered in the battery slot. If they are slightly off-center, you will feel resistance when trying to slide a battery in, which can damage the new pins.
-
Static Safety: Like all URSA/Pocket internals, this board is ESD sensitive. Touch a grounded metal object before handling the board to avoid frying the logic chips.
Expert Tip: Before ordering a replacement, use a Q-tip with a tiny bit of 99% Isopropyl Alcohol to clean the pins. Sometimes a thin layer of oxidation or "battery juice" prevents a good connection, and a simple cleaning can restore functionality!
Are you experiencing a total failure to recognize batteries, or is the camera just losing power whenever you move it?
