Description: 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 - 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: This battery is not available to ship to Alaska or Hawaii, or through any express services (2-day, overnight), or internationally. This is temporary! Check out our blog post for more information. Additionally orders may take longer to process and therefore do not qualify for same-day shipping. Sorry for any inconvenience this may cause!

Note: This item is non-returnable. If this item arrives damaged or is not functioning properly, please do not hesitate to contact us to see if further actions may be taken.

Customer Comments

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

  • Can you please post data sheets for the cell and protection circuit? Thanks.

  • Are these batteries listed to UL 1642?

  • 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.

    • In parallel, I believe batteries such as these exhibit self-balancing properties, such that if one cell’s voltage gets too low, the other charges it itself. The is nice and safe. Definitely double check what I said, I’m not 100% sure.

Perfect power density for its size

I use a 1000mAh LiPo in each of my solar-powered weather stations. The size is so small that they fit nicely in the 3.5" x 2.5" enclosures that I’m using, yet they provide more than enough power for frequent temp/humidity/barometric pressure readings.

Quality unit!

Nice battery. Doing a great job as a replacement in a Fiio E17 headphone amp. Super service! Only minor point is the high shipping costs to Europe.
