Polymer Lithium Ion LiPo Battery
These Polymer Lithium batteries come with a built-in protection circuit that protects against; over-voltage, over-current, over-discharge, and also provides short circuit protection. These are very slim, extremely light weight batteries based on Lithium Ion chemistry. Each cell outputs a nominal 3.7V at 1000mAh! Comes terminated with a standard 2-pin JST-PH connector with 2mm spacing. These 3.7V Polymer Lithium-Ion (LiPo) batteries provide a high power capacity in a very small lightweight package. This makes them ideal for many applications. They are often used in portable consumer products such as Bluetooth speakers and mobile phones.
