Description

Note: Please only use the battery capacity in the title, not in the picture, this capacity and dimension size will always change a bit in every production batch.

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 850mAh! 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 LiPo charger.

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

Mechanical Size Info:

Mechanical size will always slightly changed based every production batch, for samples you can it directly, and if you want small batch product, then you can further customize the size.
