Lithium Ion Polymer (LiPo) Battery (3.7V 2500mAh)

These are very slim, extremely light weight batteries based on Lithium Ion chemistry. Each cell outputs a nominal 3.7V at 2500mAh! 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. Please use caution when using this battery in wearable projects. When using conductive thread, a short in the thread can create sparks and heat. We recommend using coin cell batteries for beginners.

Features:

• Excellent long-term self-discharge rates (<8% per month)
• Robust power source under extreme conditions (-25 to 60C)
• Dimensions: 52 x 49 x 7 mm (±1 mm)
