These 3.7V Polymer Lithium Ion (LiPo) batteries provide a high power capacity in a very small lightweight package, making them ideal for many applications. They are often used in portable consumer products such as Bluetooth speakers and mobile phones.

The batteries are supplied with 100mm leads terminated with a standard 2 pin JST connector.

These Polymer Lithium batteries come with a built in protection circuit which protects against; over voltage, over current, over discharge and also provides short circuit protection. When fully charged the battery will have a voltage of around 4.2V and when fully discharged the battery has a cut off voltage of 2.4V.

Caution:

• These batteries are capable of delivery a high current output. If using conductive thread, a short in the circuit (between thread) could create sparks and heat. We recommend using and for wearable projects.
• When removing the JST connector from a socket do not pull it out using the connecting wires as this can damage the connector.
• Neither the battery or its protection circuit are water proof, and if being used in an environment where water contact is possible or likely then the battery should be further protected.
