Samuel, the power efficiency of the FloJack is first rate. The consumption per polling interval is ~10uAs. On a 250mAh cr2032, this works out to about 90MM polls. At the Android polling rate of 10Hz, the FloJack would last just over 3 months. Since FloJack's sleep mode kicks in when apps stop using it, we estimate typical usage patterns will allow upwards of a year of battery life.

If they sip power that well, a battery should be included. Make the user experience that much better.

A battery is indeed included with each FloJack. Thanks for the feedback, we'll add that to the KS project page.
