Ever wished you could just swap out the battery of your chipolo card like with the other chipolo products?
Here is a case that can house the internals of the chipolo card with a swapable CR2412 or CR2320 3V battery. I don't know yet how long the battery will last. Select the appropriate model depending on your type of battery.
The whole assembly is a little bit thicker than the chipolo card, but still very thin.
Use at your own risk!

Empty chipolo card
Scissors for plastic or a good cutter to open the chipolo card
