Power supply of the Internet Button

Hi Colleagues,

Im working on a wearable project. How could I power the Internet Button without taking a 9V Battery to reduce space and have more longer life? Is there any company providing rechargeable batteries, for example.

Best Regards,

Li-ion i guess?

Can we put the Li-ion battery on the top or button: Can I have the tech diagram? I need to built a project with the battery wearable. Look at the Airboard.

The schemas are all open source

So are the eaglefiles and the BOM …
