Here are the details & a full overview for the Tether Tools Relay Camera Coupler CRPBLE9 (for Panasonic Lumix cameras using the DMW‑BLG10 battery):
What It Is
The CRPBLE9 is a “dummy” battery (coupler) that fits into the battery slot in place of the Panasonic DMW‑BLG10 battery. It allows the camera to be powered continuously via external sources by interfacing with the Tether Tools Case/Onsite Relay Camera Power System (CPS). The coupler itself doesn’t hold any power; it facilitates power delivery from an external 5 V supply or battery. Tether Tools+3Tether Tools+3B&H Photo Video+3

Use‑Cases & Benefits
Continuous / long duration use: Great for workflows that require long LiveView sessions, video recording, timelapse, or studio work where battery swapping is inconvenient. Filmtools+1
Hot‑swap external power: Because the Relay CPS includes an internal buffer battery, you can change external power source (power bank, AC adapter, etc.) without shutting the camera off. Tether Tools+1
Cost and convenience: Reduces need for carrying multiple BLG10 batteries; external 5V power sources are more accessible. Polyline Corp+1
Cross‑system flexibility: If you use multiple cameras from different brands, having this coupler lets the same power system be used across those by swapping couplers. Polyline Corp
Limitations / Things to Keep in Mind
The coupler itself doesn’t store energy; if both external power and the internal buffer run out, the camera will power off. Tether Tools+1
The battery door must be able to close fully, and the cable must route through the rubber / trap door (if present) so there’s no strain or forced bending. Forcing the door closed incorrectly can damage the camera or cable. Tether Tools+1
Power draw in modes like video or high‑brightness LiveView is higher; ensure you use a good quality external power source and cables to avoid voltage drops or instability.
Double‑check compatibility: Just because a camera uses the BLG10 battery doesn’t always guarantee perfect fit/use; battery slot designs or doors may vary slightly. From sources, GX85, G100 etc. are confirmed. B&H Photo Video+1
