It's essentially just SATA with some extra proprietary bits for adding a second battery there instead and a thingy to make it easier to pop out.

Oh cool, I didn't realize they made battery packs to fit in there. Have you ever seen a pinout listed anywhere?

For the battery portion I have no idea. For the SATA portion it's just literally the same connection as a SATA laptop optical drive.

Browse the site I linked, it shows you all the peripherals you can install. One is just a drawer, heh. I usually keep a cigarillo in there just for fun.
