  • The problem is the NFC ring around the outside, but then also the room for the pivot point and the button :(

    If you didn't care about that you could probably drill through the NFC ring and fit a bigger battery holder though.

    Thing is, CR2032 are still almost certainly cheaper per Watt and easier to buy since they are produced/sold in higher numbers. I was considering adding a bigger battery but in the UK at least you can buy CR2032 from many shops on the high street. Good luck finding a CR2477 anywhere offline :)
