Lithium Ion Polymer Battery - 3.7v 1350mAh

Lithium Ion Polymer Battery - 3.7v 1350mAh

These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cells outputs a nominal 3.7V at 1350mAh! Comes terminated with a standard 2-pin JST-JCY with lead connector - 2.5mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized LiPo charger.

Battery includes built-in protection against over voltage, over current, and minimum voltage.
