@alanhortz If you can wire two CR2016 in parallel that would work well as a power source. Both batteries should be fresh when installed, because lithium coin cells do not tolerate reverse current well -- which the weaker of the two would receive if imbalanced.
It would not work off the shelf with MetaWear because there is no protection circuit, battery charge current is a little low, and maximum discharge current is a little underrated. MetaWear needs to be able to burst around 15-20mA for the radio.
With their additional circuitry it might work together, it seems they are using a supercap to help with burst current.
Also consider that the capacity is 700uAh which is about 150x less than our standard battery, so it will not last very long.

Interesting technology.
