Battery for Teensy 4 & Audio board

Hi guys,

I’d like to add a rechargeable Battery to a Teensy 4 & Audio board project. I would also like this to have a usb data pass though so that I only have on usb socket for both charging and data.

I assume this is possible? but I’m really not sure which charging board and battery to add in. I’m also concerned about voltage, I don’t want to blow up my teensy etc so I’d rather ask you guys for help.

Hope you can help me out? :).
