### 3/5 — Multi battery support

*2023-11-16*

How about making the app add multiple batteries without having to close the app and add device each time. I have 4 batteries and would like to have them added and the ability to choose which one I want the stars on. Now I have to close the app, add device and then see the stats. Please make this easier.
