Description: If you need some juice, this 6Ah Polymer Lithium Ion Battery is for you. These are very compact 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 2000mAh! This solid 3 cell pack (6Ah) 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.

These three cells have been matched for internal impedance and can be fully charged and discharged in parallel. 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.

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

  • For those of you that don’t want to read the datasheet, max charge and discharge is 1C, normal charge is 0.2C. The wire is 22AWG so it can carry up to 7amps. However, I believe the JST-PH connector is only rated at 2A, but I could be wrong.

    • some RC guys will push them 5A continuous without heat issues. But if you want to get technical, they typically have 10-20milliohms of resistance, so calculate heat load based on that.

  • You probably shouldn’t. Since the 3 internal cells in the pack have been impedance matched with each other, you can apparently ignore the rule of not discharging and/or recharging them in parallel. I don’t work for Sparkfun, but my guess is that there would be no guarantee that any two battery packs would be impedance matched with each other.

    • This would have been a little more useful as a reply to j.tilghman question rather than it’s own comment. For those that see this is several years and don’t know what question he/she is answering it was: “Could you charge 2 of these packs in parallel”

  • semaf / last month / 1

    I guess those are 3x 2A Batteries. Does each of them has Protection Circuit?

  • Check your “normal charge current” math please. 6A * 0.2 = 1.2A Charging only at 22mA would take over 272hours, assuming 100% efficiency, to fully charge.

  • Is it possible to charge this beast wth SparkFun LiPo Charger Basic - Micro-USB (PRT-10217) ?

  • Weight is in the datasheet:

    3.13 Weight Less than 150 g

  • This is tiny! My 2Ah phone battery is bigger! How is this 6 Amp Hours?!

  • Does it make HOT MAGMA? :)

  • Could you charge 2 of these packs in parallel ?

Not quite what I need

The dimensions do not provide a good fit for my project. Purchased a previous battery that was discontinued but fit perfectly with my project.Not sure what other options I have available.

Well not the best!

I have bought many items from Spark fun with no issues at all but this one has issues. The JST connector was smashed and not usable at all.

Sorry to hear that your connector got roughed up in transit. If you’ll contact our tech support team, they can get that straightened out for you.
