Lithium Polymer cells are amazing. Light, good voltage, and whompfuls (yes, whompfuls) of current-delivery ability. This last bit can be a dangerous aspect when you're wearing a LiPoly battery next to your skin, like you often do with e-textile projects.

This particular battery has been specially prepared for use with e-textiles, as it features a built-in current limiter, capping the current dump to within 240~380mA. Additionally, shorting it out will not cause a catastrophic failure, which can be disastrous with LiPoly cells, especially when near human flesh!
