-Based off the BQ24133 battery charger chip. Does automatic selection of battery versus 12v input for driving the Pi. Also allows for simultaneous charging and playing. The power board also includes a battery power gauge, and a cell balancer to keep the two batteries matched and happy.
Any chance you could share your schematic? I'm about to design the power path for mine and I was just going to use the adafruit design (which is just a reference for charge/boost IC's anyway) but this sounds very interesting

I updated the original post with schematics and layouts for the boards I did

Any idea how to wire the home button board to attach to the teensy unit?

I didn't use a teensy, or the original button board...I did a custom design for both. But I did find a lot of great info in this thread when I was doing my build:

There are pictures in there that describe the pinout of the button board.

These are the batteries I used:

They are only 5.5mm thick, but they are very long. Batteryspace has a great selection of options though, just be sure to also get a protection board for it!
