The puck is some ~6mm thick, I would like to reduce that to ~3mm by putting the battery next to it instead of on the back.
It is pretty easy to take off the button and the battery housing. But I wonder how i should connect power.
Positive of the battery is easy to connect to the large positive battery pad on the back. But i need a removable way to connect the negative too. Some large area or a pin hole maybe? The chip housing cant be used as a negative right?
