- Lithium Ion Battery - 6Ah
If you need some juice, this 6Ah Lithium Ion Battery is for you. These are very compact batteries based on 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 Polymer 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: 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.

Monitor your LiPo battery with the LiPo fuel gauge! In this tutorial, we will be using the MAX17043 and MAX17048 to monitor a single cell, LiPo battery over the Arduino Serial Monitor. We will also connect a display to view the output without the need to connect the microcontroller to a computer.
Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Lasts Forever!
I use this battery to power the four motors on the Multi-Chassis Basic 4WD and am more than satisfied with its performance. Fully charged it provides around 4V. After using it on and off for weeks it wasn't even bellow 3.7V yet! A great product that saved me a lot of double A batteries!

Very compact and plenty of power!
I'm building a small radio transceiver using this as a power source and it's perfect! Using a Arduino compatible board with built in charger makes for a compact design.

The 6Ah LiPo battery working as expected
I have had this battery deployed in my solar powered weather station for 20 days. During this time the battery has operated reliably in temperatures ranging from 24 to 60 degrees F and relative humidity ranging from 40% to 98%. I've experienced no battery outages during this time.

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.
Works
And the capacity is HUGE.

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.

Bad delivery timing !
I am not satisfied with your service because I couldn't get my batteries until now!
They were picked up by an agent of my office and they are waiting for the next flight.
I bought it online from you because you told me that it will reach my hotel on October 19th!
I had to leave my hotel on October 20th! I stayed there between October 17 to 20.
And I missed my package because your horrible logistic service decides to put it in a warehouse on October 19th! When I called around midnight on the 19th, they told me it will reach my hotel on October 21st!
That's your fault!
I checked if I had to pay a rush service! You told me standard transportation will arrive at my hotel on October 20th!
And you didn't respect your engagement!
You better improve your service or close!
I am very angry!
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"
Is it possible to charge this beast wth SparkFun LiPo Charger Basic - Micro-USB (PRT-10217) ?
Yes. It should take about 15.6 hours to charge completely though.
What's the recommended charger for this?
Can I charge this with an adafruit feather?
Is there a curve floating around somewhere of the voltage or charge characteristics as temperature changes?
Hello, I've been trying to use this 6Ah battery to power my LilyPad MP3 player, but it didn't work (no "power on" light, and there even was some very little smoke coming out from the Lilypad when I connected it !), while it works very fine with a smaller battery (a 850mAh). Is that normal ? Both batteries are Lipo 3,7V so I don't get it. Thanks for your help !
yeah, i meant series
if i want to run my arduino at 5volts, can i stick two of these in parallel (giving 7.5 volts) and work that way, or is that just the wrong thing?
2 in parallel will give you 3.7V. 2 in series will give you 7.4V which will technically work, just make sure you don't charge them that way as charging Lipos in series is tricky. Also keep in mind that a fully charged Lipo is closer to 4.2V, that shouldn't be a problem, but just a reminder.
Personally I'd just use one though. The ATMega328 should work fine at 3.7V even at 16MHz. In fact we've had no problems running the Open Log at 3.3V/16MHz (although it is just out of spec). All you GPIO will be at 3.7 and as long as whatever you have hooked to to the Ardunio is fine with that the Arduino should be fine as well. To do this you'll want to put the power on the 5V pin and not the Vin (which goes through the regulator). You'll also want to remove power from the 5V pin when you connect the board to the computer for programming so you don't have 2 sources on the 5V pin.
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.
Weight is in the datasheet:
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 ?
