Pentax 645 Battery Holder - 9V conversion

Do this modification at your own risk. If you don't know what you're doing, and install the batteries incorrectly, you may damage your camera. I won't be held responsible if you break your camera.

This revision of my own original design, is for being able to use 2-9v batteries in your Pentax 645. The batteries MUST be hooked up in parallel. Final output at the terminals needs to be 9v, NOT 18 volts. Check with a meter if you're not sure. Also ensure you've got the polarity correct. I have not made a completed holder yet as my currect holder works. I've designed this for the Pentax 645 community. I'd recommend using the "T" style terminals (as seen in one of the photos), as this will just make the fit better. You will need rivits to get the holder to make electrical contact with the camera. (make sure they're steel and not aluminum) Only thing I can add is make sure you double / triple check everything. You don't want to damage your camera with incorrect voltage / polarit
