While the battery door is not removable according to the internet.

It can be removed by cutting off a small bit of plastic.

It's a very complicated mechanism if it wasn't designed in China.  Suspect it was designed in China.

The door can be reinserted as a gap filler, if the camera is stored in an enclosure.  It still won't shut down properly.

The easiest wire routing for the enclosures ended up being a notch.  The trick is keeping the buck converter always powered in order to retain the system clock.

All new tripod mount with cooling fan.

It took 3 tries to get the battery flush with .32 layers.
