Description: 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 cell outputs a nominal 3.7V at 1000mAh! 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.

Note: Due to the requirements of shipping these batteries, only two batteries can be shipped together at one time and orders may take longer to process and therefore do not qualify for same-day shipping. Additionally, these batteries can not be shipped via Ground or Economy methods to Alaska or Hawaii. Sorry for any inconvenience this may cause.

Customer Comments

  • Are these batteries listed to UL 1642?

  • What is the maximum charge and discharge current of this battery? It is given in ‘C’ for LiPo batteries.

  • More of a question rather than a comment, but here goes: What would someone recommend, for say, using two or more of these in parallel? I have a sudden interest in battery powered devices, and I know that 1000mah is not going to be enough capacity, but 2200mah would be plenty. Ideally, I want my Sunny Buddy to charge them.
