I get this question all the time - what size battery should I use with the trigBoard?. the answer, well it depends. The trigBoard is an on-demand type of application, so battery life is going to vary depending on how many times you "wake" the trigBoard up. All of the info in this video should help you out with any battery powered application, and please keep in mind that this is all just a way to "estimate" life... there are many other factors to this, especially self-discharge. Don't think you're going to get 30yrs from a li-poly cell.
