Feature Description

Hello,
firs of all. Great project. Realy good job.

Woud it will be posible to add Battery monitoring on some pins of ESP?

Justification

I have been runing this https://www.printables.com/cs/model/582641-bambu-lab-p1pp1sx1c-18650-portable-display-xtouch
case as my daili driver. But i dont know how much is battery charged.

It woud be perfect if i coud monitor battery in top bar. That hase Wifi, Camera, Timelapse icon.

You alredy have I2C temperature. (Witch in this portable version i "cant" use. And port is free to use with diferent I2C device)
So i think. It woud be easy add suport for something like: MAX17043
