  4. Polymer Lithium Ion Batteries - 100mAh

    Polymer Lithium Ion Batteries - 100mAh

    $8.35

    Out of stock

    This is a very small, extremely light weight batty 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 100mAh! Comes terminated with a standard 2-pin JST connector - 2mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger.

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