Mounted my quest 3 (will work with quest 2 headbands) on my skadis board and I have a replacement headband with a built in battery, but the charging port (USB C) is on the bottom like a lot of 3rd party headband, so I bought a 90 degree usb c magnetic charging plug from amazon and made a mount that when you hang the headset on the skadis board mount it connects to the charger automatically, this saves removing the plug from the quest2/3 and from the battery as the headset battery and headband battery will fully charge at the same time. (we all know about the Quest 2 charging port melting!!!)

To attach the usb c mag charger with a small bit of nano tape or double sided tape to hold it in place, all you need to do is make sure you align it with the charging port.
