How about a section about both how to add Batteries, or maybe how to create a portable battery pack for the esp's that provides the correct charge voltage and power requirements. Or maybe even a link to a battery pack on Amazon that provides the right output to power the three Boards. Since most battery packs(Mainly portable phone charger battery packs) only output at most 5v, and it's pretty hard to figure out which ones will and won't work. Or as I stated above, could do a guide on how to wire up a power cell to the XIAO's since most of them have charge circuits already built into them, then you could just connect them to a usb-c hub, along with the IR board which you could just hook up to a portable phone charger pack, and connect the charging port of the phone charger pack to the hub, and then connect a usb c cable to the hub when not you're not using your headset, to recharge the battery pack and the power cells.
