Hi,

Looks like the WiFi TinyShield needs its own batteries. Now I know I maybe asking for the impossible - I am looking out for the small batteries with long battery life. I would appreciate it if somebody could provide me with some options so that I could trade off battery life with size.

HI Nikhil,

True, a number of the higher powered board (like the WiFi, GPS, etc), draw too much power to be run off a coin cell battery.  Alkaline batteries can certainly be used (like AAA or AA's), Adafruit and Sparkfun also have a number of small rechargeable Li-Ion packs that can be used with the TinyDuino that would be able to power the WiFi. 

Thanks,
