Replacement:DEV-10085. We don't sell this board any longer, however we do still sell the LilyPad Simple Power which is essentially the same board but with a power switch. This page is for reference only.
The LilyPad Battery Connect simply gives you a connection point for a battery or anything else you might want to plug in to your LilyPad system. It consists of a single 2-pin JST connector on a small LilyPad board with positive and negative terminals.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!
Note: The LilyPad Coin Cell Battery Holder is a design conceived by Felicia Williams of Boulder, Colorado. Also, a portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

I'm assuming I can't use this to connect a lithium battery (3.7V) to my Lilypad (5V) without some kind of regulator correct?
In general, you can solve that sort of problem with a boost converter. But the LilyPad has a minimum operating voltage of 2.7V. I would endeavor to stay away from the minimum, but there's no reason that a 3.7V battery can't do the job (to some reasonable level of discharge).
