FujiFilm GX680 Medium format camera - battery replacement

My old FujiFilm GX680 Medium format electronic camera's battery is dead(!) and so old it's really hard to find a replacement. SO, I Dremel'd the old battery case (carefully!) and took the old "base plate" off and made a battery holder for 6 AA batteries or rechargeable batteries.
Works a treat and easy to replace the batteries when needed.
I am making a plastic cover for the adaptor at the moment to cover up the plug but works fine as it is. The battery is 7.2v and about 700mAh.
There is a company online (many actually) that sell effectively what I did;
www.ebay.co.uk... (for example).
These are about £50 ($65). But as I had the electronics and a Dremel I would do it myself. There are a few captcha's and if you try this and have problems - leave me a comment.
As usual I am doing this so that you can see what I do. I do not recommend attacking your battery pack with a Dremel! - I do it - but that is up to my own safety. You should NEVER puncture a rechargeable battery under any circumstances as it is VERY DANGEROUS.
Let me know if you give it a go!

Uploaded 12 days ago, what a coincidence! I just learned about this camera today and I think that the tilt/shift would satisfy my landscape photography dreams without having to spend a fortune on home dev kit for sheet film that 4x5 would necessitate.
So long as the landscapes are accessible by car, anyway! Thanks for the video

Glad you liked it :)

The heat sink you mentioned inside the battery pack is a thermal fuse. I couldn’t figure out what it was either until I hooked an ohmmeter up to it and heated it up. Only then did I see “70C” printed on the outside underneath the heat shrink. At 70C it quickly goes from zero resistance to being an open circuit. Maybe just a bimetallic strip inside or something that gets hot with enough charge current. 1:49
