See my solution here:

Your setup for a wall mounted tablet

Nice work! Have a look at mine [20220730_215407 (2)] [20220716_192923] Behind the wall: [20220716_192943 (2)] Setup: acustic panels: Fibrotech Client: Odroid C4 running Andorid Pie with Openhab App. Display: Waveshare 10.1

For static solution I would always recommend no battery and wired LAN connection.
Everything else is a bad compromise.
