This is a very small, extremely lightweight battery based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cell outputs a nominal 3.7V at 110mAh! Comes terminated with a standard 2-pin JST-PH 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.

Note: Be careful with the JST connectors. They can stick in pretty good and tugging on them can damage the connector.

Dimensions: 32 x 14 x 5.5 mm (±0.5 mm)

Weight: 10g
