Polymer Lithium Ion Battery (LiPo) 3.7V 4400mAh

*LiPo batteries require special handling and use for safe operation. We recommend that you read our tutorial on using LiPo batteries safely if you haven't worked with them before*

This Lithium Polymer Ion based battery is a slim, lightweight battery that is perfect for a portable project! LIPO chemistry is the highest energy density chemistry around and due to that, you get nominal 3.7V at 4400mAh! This battery comes terminated with a standard 2-pin JST-PH connector - 2mm spacing between pins. Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries.

This battery is terminated with a standard 2-pin JST-PH connector (that is with 2mm pin spacing).Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries.

Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries, or you risk some damage to your battery.

This battery includes built-in protection against over voltage, over current, and minimum voltage (all present under the yellow plastic at the top of the battery).

Note:

• The battery is rated for 2C continuous discharge, however, the wiring is only rated for 1A so be careful.
• The JST connectors can also be quite fragile. While they stick in quite well, tugging on them can damage the connector. Check this tutorial from Sparkfun for the safe removal method.
• You should also exercise caution when using these batteries in a wearable project, unless you are seasoned with LiPO operation you should stick with Coin Cell batteries.
