Oh, and as for the tablet style battery, you might run into issues. I had the same idea and it's just a tad too much without modifying the gamepad shell. Nothing a little dremelling and something like plumber's putty and paint couldn't fix.

A little late on my reply.... Got distracted by Zelda....

I meant the 7in board has a touch input connector, so if you got a digitizer that matches the pinout (possibly doesn't exist), but again that means you need to source the board in the first place.

Edit: On a side note, anyone know where I can find a Official Pi 7 Inch board without the screen? It's painful to buy 2 screens and then shove one in a box for months That's the unfortunate part, I can't seem to find them anywhere. You might want to contact the manufacturer.

Alright, funny story. Also, to help anyone who's doing this project, I couldn't get the power on wiring/power off script to work if I updated raspi-config. I did work without a hitch after I reinstalled retropie 4.1 though... 3 weeks of annoyance....

On to debugging the battery monitor section.

You could probably wire a button, possibly the 'tv' button to write a config change to use a particular HDMI output. I might suggest using the display board from the official 7in display as the DSI connector works with the 6.5in screen he used (I can confirm this, as I fried the original board and h...

I'm having trouble wiring up the power on/off part. I can get it to turn on but I have to hold the button and when I release it the 5v line from the powerboost shuts off. Any suggestions would be appreciated.
