Lithium Ion Battery - 2000mAh
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 cells outputs a nominal 3.7V at 2000mAh! This battery 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.
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: Although these cells are rated for 2C continuous discharge, the wiring and connectors are only rated up to 1A, so be sure to take that into account when determining your power requirements.
Note: Be careful with the JST connectors. They can stick in pretty good and tugging on them can damage the connector. Check this tutorial for an easy way to remove them safely.
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.

Great capacity, small size
I ran an ESP8266 board (without WiFi enabled) and about 160 WS2812 LEDs off of this for a Halloween costume and it worked out great. I was worried about battery life with such a physically small battery, but my tests beforehand showed that it could run for over 6 hours without exhausting the battery; nice!

Works as designed
Powers my Photon project for a couple days when primary power fails. This allows the Photon to still provide important data until primary power can be restored.
Exceptional life
Improvement on a Craig CMA3559 Bluetooth portable stereo speaker. Specs claimed ~3 hrs on the 1000mAh li-po. I was only getting maybe 1.5hrs. Upgrade: removed connectors, stripped wire ends, soldered and heat-shrink insulated two of these 2000 mAh batt's in parallel with the existing batt. My now 5 Ah mini-bank has been used for over 15 hrs and hasn't required a recharge yet! Now a better product for the worksite and movies on the phone/tablet!!!
Solid battery - careful with wires though
I use this in a classroom setting where it gets handled by a lot of 4th and 5th graders. Considering all of the warnings from Sparkfun about the difficulty of pulling out the JST connector, I anticipated losing a connection from there at some point; therefore I have been extra careful and anxious about it. What did happen is the wire broke off the battery end. This happened fairly recently after we started using it. The negative lead sheared off at the solder point. Fortunately it was an easy fix. The yellow tape came off easily, and the solder point was obvious. One good blob of solder and a few wraps of electrical tape later, and it was as good as new!
Great Battery
I've bought 4 of these batteries, and they work great
Good for providing a LOT of power for Tinyduino (but needs different plug)
It requires a different plug, but the capacity of this is GREAT for powering the Tinyduino. I've wired it up with a small cable to change out the plug and keeps the Tinyduino running multiple days as compared to the Tinyduino battery that doesn't last over night.
Great power source at a great price.
We're using these batteries in a product called the X-harp - an all electronic harmonica, and find that they power our instrument solidly for at least 8 hours - which is awesome for a musician performing live. Some caveats: these batteries store an impressive amount of power - which means that if damaged, they can release an impressive amount of energy. But if they are properly cared for, they are quite safe and very effective.
loose the cord!
Combined with a Fio, this is an amazing helping hand. I broke the leads. I suggest a dob of hot glue at the point where each wire "disappears" to provide strain relief.
Its a battery. It works.
I bought this battery to use with the C.H.I.P. computer. It works great.
Some more notes here: https://jdbtechnotes.com/category/chip/
works as expected
no complaints.
Appears to be good battery
Battery charges well with the Sparkfun charger. The connector, however, does not fit the small GoPro camera transmitters that I am using. Need to have a choice here.
good
Thank you. Everything is fine.
Works!
Great for battery functionality for the Photon!
Size is incorrect.... :(
So we 3D printed a batch of cases for the battery and the electronics while waiting for these to arrive. Unfortunately when they arrived they were BIGGER than the dims or the cad file. We had the same issue earlier this year with the 400mAH Lipo - we had used 40+ in custom 3D printed cases, ordered more of the 400 (Same part number) and started printing 35 cases. When they arrived... they did not fit - the new ones are a few mm bigger :( :( in the end we had to send the print job to an outsource agency as we did not have time with 2 printers to make the 'ever so slightly larger' cases in house. :(
I'm very sorry that this issue caused you to have to print more cases. These soft sided batteries can have some variance (though slight) from batch to batch. They also can fluctuate slightly in size based on environmental conditions, so it is good to build in some slight tolerance in your design for extra space. Again, my apologies that that ended up not working with your original case designs.
Excellent
This thing is amazing. I have a photon that I'll be using as a garden sensor and it nails it!
Worked as expected
I bought this battery along with a Sparkfun battery shield to power Photon. It takes many hours to fully charge the battery, but then it is able to drive Photon for about 24 hours. The cable and JST connector are also in good quality.
Works Great
I purchased this along with a Photon charger and it works perfectly.
Needs more rugged wire attachments
I am still designing the device in which I will use it. I like the compact charger that came with it. I did a lot of measuring for of the first battery in order to design its compartment in my new device. One of the lead wires broke of inside the battery. So I bought a second battery which I am handling very carefully.

As advertised
Arrived in good shape, fully charged. Can use male jumpers with the connector, making trouble shooting simpler. I gave 4 stars because they haven't exceeded expectations and I haven't had a chance to use them beyond initial testing.
Big power in a Small Space
I build connected sensors that are deployed in our local parks. These sensors run on solar power and have to operate safely over a wide range of temperatures. These batteries have proven to be very reliable.
Solid product.
With a Sparkfun charging circuit and a little thought, makes a great cell phone portable charger. I'm probably going to put it all in some kind of object that doesn't look like a charger. That would be less expensive than a retail product and more fun. Read the precautions that Sparkfun provides, they matter.
Good battery
I bought this to power a Moteino/RFM69 with a Temperature/Humidity sensor in a remote location. It works great.
Plug and play, worked great
No setup necessary, plugged into the shield and worked immediately. Instant gratification!
I put a nail through one of these, and it didn't explode... It did get warm enough to slowly boil off water though.
COME BACK IN STOCK! I COMMAND YOU!
ALRIGHT!! COME ON! ITS BEEN THREE WEEKS!
Please get them back in stock!
now there is 1607 in stock is that enough?
Nope ;)
I second this notion!
What charger should I buy to charge two prt-08483 3.7 v 2000mAh lipo batteries that are wired in parallel.
Does this have undervoltage protection included?
In other words, if left connected to a load will the battery shut off before discharging beyond the point of no return?
Where is the CAD model in the GitHub folder? I searched for the SKU and could find it :)
What is the wire length of these?
Looking for a lot more than the maximum quantity of 2 of these. Does anyone have a source where I can order bulk? Thanks!
Email customer service at cservice@sparkfun.com and we maybe able to help you out.
What exactly does it mean by, "protection against...minimum voltage", in terms of leaving a device powered on for long amounts of time?
I'm planning to use this LiPo cell with a Solar Buddy board for charging. I'm trying to find out whether there is an NTC thermistor installed or not, the data sheet for the protection circuit i quite hard to read and only states XXX on the NTC spec. My application will be outdoors all year, i.e. the temperature will be well below freezing during winter and if I understood it correctly you really should avoid charging at subzero temperatures.
Why is there extra shipping stuff necessary?
Check out this blog post from a few weeks ago. It is all about all the shipping stuff necessary for lithium batteries.
What is the cutoff voltage of these batteries? 3.0V? 3.4V?
Did you try looking through the datasheet for the protection circuit?
Can this work on my PS4 controller? I need to know my battery charge dies to quickly. Thanks. If not where do you suggest I get one?
Hi everyone,
I have a question. Can I charge this battery using the LilyPad Arduino Simple Board and the FTDI connector?
Thanks,
Can two of these batteries be used in parallel.
Can I charge this Li-ion battery with the Lipo Charger/Booster (PRT-11231)? The battery that I received is different from the one shown in the picture and is labeled 'Li-ion' - GSP 585460. I thought that I wasn't supposed to charge Li-ion batteries with Li-Po chargers?
Could we get a picture of all of the battery offerings side by side? I recently saw this one in a saw and was surprised (foolishly I suppose) by how much bigger it was than the 1Ah. Some reference other than the specs and a quarter would be nice.
Unionfortune has UP 1642 certification for this 2000 mAh LiPo battery. Does anyone know if the have IEC 62133 Certification?
Can these batteries be connected in series ?
FYI your picture is confusing you show this is a one cell. Yet in the photo showing off the connector you show a 3 cell battery. Just thought I would point that out
The JST close up image is borrowed from the 6 AH model of this battery series, the connector is identical, however as you stated, there's only 1 cell in this variant.
Is this cell UL certified? I need safety data sheets for a device I am working on, which uses this cell and the MSDS document would appear to be from a different manufacturer.
Is this battery UL certified? The MSDS datasheet would also appear to be for a different manufacturer (Sony).
Is this battery IEC 60086-4 compliant, no info. in the data sheet.
Can I connect three of these 2000ma batteries in parallel to make one of these:
https://www.sparkfun.com/products/8484
(6A)
You can, but you need to be really careful if you decide to charge them when connected together. They need to be balanced to prevent any issues or damage to the cells occurring.
Can I use the Lipo Charger Micro USB https://www.sparkfun.com/products/10217 to charge it? Would it take 4 hours to fully charge or longer? If this isn´t the best charger, which one is? If my circuit needs 7.4V can i simply put two of these in series? If I add two more in parallel could my proyect work good at 7.4V and 3A?
My project requires about 2A continuous discharge from this battery. You mentioned that the wires are only rated for 1A. What can i do so I will be able to use this for my project? Can i just unsolder the connector it has right now, and solder higher current-rated wires?
You can replace the wires; they're soldered to large pads on the protection circuit board and are fairly easy to swap out. Obviously be extremely careful while doing this; as Boeing is finding out Lipos can be unforgiving if mistreated.
Also, since 2A is at the top end of what this battery can provide, you might consider using a 1S RC-style battery without protection circuit, which could provide much more discharge current. We currently don't offer any 1S cells (the lowest we have is 2S 7.4V), but we're looking into it.
Well, that too. Boeing is using cobalt lithium ion, not polymer lithium ion.
Also, my dad once suggested that I use the hot soldering iron for such a battery as lithium.
I notice that the description says that "the wiring and connectors are only rated up to 1A", but the datasheet on the connector says 2A. Is the limitation in the gauge of the leads? If so, would it be possible to (a) replace the leads myself and (b) provide the next larger size for future versions?
hi!I have some questions about the performance of my LiPo cell. I don't know if I'm doin' it rigth but when I measure the voltage when charged I only get 4.2 V and I think if its cells are in series it should have a greater voltage 3 x 3.7V aprox. 11.1 V. What can I do to get this voltage? I have the LiPo basic charger https://www.sparkfun.com/products/10217 . Thanks so much!!!
I'm pretty sure this is a single cell battery. The photo for the product even shows markings indicating 3.7V (which, when charged anew, would be about 4.2V indeed). If you have 3 of them and you put them in series you should get ~12V. Are you sure that each individual cell is at that ~3.7V level? And if they are, are you sure you have them wired in series correctly?
Also, please keep in mind that you cannot use the LiPo Charger Basic - Micro-USB to charge the 3 batteries while they are wired in series. You will have to charge each of them individually, or look into a balancing charger and appropriate wiring for that.
Kamiquasi is correct, this is a single cell battery, thus the voltage you're seeing is correct. If you want a three-cell battery we have this one, which requires this charger (plus a >12V power supply).
Just a note: These are actually UnionFORTUNE batteries. UnionBattery will take you to a Lead Acid battery producer.
No biggie.
In stock in stock!! Man, I think you guys should order 2000 piece of this at once since they went out of stock so fast every time.
When are these coming back in stock??? I got projects waiting loll
We are working to get them back in stock as quickly as possible. I recommend getting your name added to the auto-notify list, as these are pretty popular batteries.
Hi –
When will this item be back in stock, please? Polymer Lithium Ion Battery – 2000mAh
sku: PRT-08483
Thank you!
Is it OK to power Arduino with TWO of these in series? Also, I looked at LiPower booster/LiPower Shield and it says it boosts the 3.7 volts of the LiPos to 5 volts., but I thought Arduino takes 7-12 volts? Can someone explain this? Thank you.
The regulator on an arduino takes 7-12 volts, and then regulates it down to 5v. If you were to take a 5v supply and plug it into the 5v pin on the arduino, it would indeed power your arduino just fine, without using the on-board regulator.
technically you can power an arduino with 5V directly into the 5V pin. BUT it is risky. There is no input protection on the 5V pin so you risk damaging your arduino if you run external power into it.
Can I use this to charge my iPhone/Android Device?
not directly, you'd need something in between the two.
Could i use this battery for a walkie-talkie that uses 3.7v with an unknown mAh? Will the mAh output from the battery affect the walkie-talkie? Thanks, Nate
yes. you really only need to match the voltage. the Ah rating (or mAh rating) is how much current it can provide, or how much power it stores. the bigger the storage, the longer it can run. so, if the original was a 1000mAh, this could run (theoretically) for twice as long. If it was a 4000mAh, it can run for half as long, etc.
You better keep this stuff in stock or I'll have to wait and wait!
when will we see this item back in stock again?
So, How about stacking 2 of these in parallel to get 3.7V and 4000mAH. Think they could be charged on a single cell charger IC while still hooked in parallel? After all, wouldn't the charger only see a "big" single cell LiPo?
Hi -
When will this item be back in stock, please? Polymer Lithium Ion Battery - 2000mAh
sku: PRT-08483 RoHS
Thank you!
we have 2000 on order and in shipment right now. Give it a week or so hopefully.
Any idea why this battery cuts power just below 3 amps? I though that continuous discharge current was 4 amps?
What charger would you recommend for this battery? A url link?
Also, this says 3.7V per cell... Arduino Mega suggests +- 6V-12V?
Will this work? Will i need to buy 2 of these?
so for the average Arduino Mega board. How long would this battery last?? for reference, i only currently have a speaker (8ohm), small LED and a 2125 accelerometer
Almost the equivalent of a 2000 Farad Supercap!!!!
Removed by user, wrong product, sorry...
The dimensions listed are not right.
Its actually about 54x63mm. Not counting the yellow on top it may be 54x54mm.
I need to put together a 24v supply. Can it be done with this cell and if so, what charging setup will work?
I need to put together a 24v supply. Can it be done with this cell and if so, what charging setup will work?
With 6.486486486 of them. :)
Ok ok. A buck/boost IC should do the trick. But it will be much less than 2amps.
Hi,
Could someone tell me the formula to calculate the max life of this battery?
Thanks in advance
Battery capacity is measured in milliAmp-hours (mAh). This one is 2000mAh, so it can provide 2000mA for one hour, or 1000mA for two hours, 500mA for four hours, 100mA for 20 hours, etc. Divide 2000 by the mA that your project draws, and you'll have the number of hours it should run.
Oh, it was that simple. I feel stupid now xD
Thanks a lot :D
Dividing capacity by current draw to determine battery life is a good rule of thumb, but not exact. If you need to be more precise, the following might be useful: Battery capacity is rated over a given period of time at a given current draw. As best I can figure out from the datasheet, this one (I think) is rated at 400mA over 5 hours. But if you draw more than 400mA, you will get less than 2000mAh out of the battery. If you draw less than 400mA, you will get more than 2000mAh out of the battery (i.e. the battery will last longer than 5 hours). The difference can be quite dramatic. Most battery manufacturers include a graph in their datasheet so you can determine the exact amount of time before it goes dead in your application. Also, the more times it is discharged and recharged, the less capicity it will have. Most also include a graph of the number-of-discharges vs. battery capacity. Also, for many batteries, the deeper you discharge them before recharging, the less cycles you get out of them before they have to be replaced. Again, this is usually graphed by the manufacturer. I don't see any graphs in this datasheet, but there are a few datapoints included. These are things you may want to consider if battery capacity and cycle life are important in your project. Have fun!
Ohh men :S I want to build some stuffs, first the El Sequencer was out of stock, then the El Wire, then the Inverter, and now this battery... come on! :(
BTW, I would really like to have the stock status of a product on my wish lists.
This may sound noobish, but do these come pre-charged or do they require me plugging it in to the LiPo charger for like 4 hours first?
Just check it out with your multimeter.
Wow i feel dumb. DUHHH
Can somebody please tell me what the datasheet means by the unit C5A for charge/discharge rates? I also noticed that SF lists 2C as the continuous discharge. What is this C; Coulombs?
C represents capacity. Since this is a 2000mAh battery, and continuous discharge is rated at 2C, you can safely discharge at a rate of 4000mAh continuously. I was also confused as to the C5A, but I chock that up to the poorly done datasheet as there were lots of other character errors in there as well.
I'm unable to click the tutorial link
Is there a step down module available for these batteries for use with 3.3 VDC applications? Or are these close enough in voltage for it not to matter?
Check out the MAX8662/MAX8663 PMIC (Power Managment IC). It provides all aspects of power management in a battery power system. Single cell Li-Ion charger, automatic power switching between external supply and battery, 2 on-board .9-3.3v buck regulators, 4 linear regulators. The list goes on. The only draw back is it is only available in a TQFN style package. Perhaps SF can create a breakout for this?
does anyone know if it is possible/safe to put two of these in series so I can get 6-8 volts
Not without an appropriate battery balancer. <br />
<br />
http://en.wikipedia.org/wiki/Battery_balancer<br />
<br />
I would advise again unless you really know what you're doing.
Just got one of these and charged it with the FIO board until the charge light turned off, then tested it with a CBAII tester and custom adapter, while it was also running the FIO board... guess you can't post a PDF attachment here... anyway it started out at 4.2V, and with a constant 2000 mA load (C/10) at 3.7 volts it had put out 1.8 Ah, at 3.3V 1.9 Ah, and 2.8V 1.92 Ah. So that seems pretty much on spec considering the draw of FIO running the blink LED code. OK so I measured FIO drawing about 4 mA red LED off and 5.5 mA LED on. So call it 5 mA for 10 hr - .05 Ah more. So the cell comes in at about 1.97 Ah to 2.8 V. Count on 1.8 Ah to 3.7V as a more practical cutoff.
could I make a cell of 4000 mAh with two of these in parallel?
Yeah, that should be fine. The 6AH ones we have are essentially three in parallel.
Is that safe in terms of charging with just one charger? Or does each cell need to be managed individually?
Can I ask nicely if SparkFun ever plans to sell a 4000mAh version? It would be a nice middle ground between this unit and the 6 amp battery...
So if I hook this directly to a Arduino Pro, will the Arduino charge it? Or do I need a LiPoly charger in between the battery and the Arduino?
You will need a charger. Check the related items for chargers.
Question, this battery can work with the Arduino FIO, and can be charged by the USB connection?
Answer, yes.
Just wondering, have any of these ever gone up in flames (LiPo fire)? While I'm fine using them in my own projects, putting one in a reverse geocache box makes me wary - I don't want someone's house going up in flames!
We had a guy call in once that said his LiPo spontaneously combusted. I have no idea what that was about. he said it was just sitting there and it went up in flames all of a sudden.
If you respect the secs you'll do fine. They rarely explode.
To clarify, charging with a MAX1811 at 500mA won't cause a LiPo fire.
And if I put this battery in a charge sack, and it did explode, will the fumes ignite a wooden box? (I'm thinking yes)
Hello -
Do you know if I can use the iPhone USB charger to recharge this battery?
Many thanks!
If it explodes then no.
Most cell phones it seems like use 3.7V LiPos. Mine does anyways. Try it and find out...maybe wear safety glasses while you do.
Quick question, i plugged this into the logomatic v2 and i cannot seem to get it out. How do you unplug this type of connector? Thank you
I usually use needle nose pliers. I grip on the sides of the connector not the top and bottom. There is no locking mechanism or crimp or anything like that, yank it and it will come out.
i guess it took a lot more force than i thought, Thanks.
what part number is the JST connector, NOT receptacle please?
We only sell ones with the wires pre-crimped on;
http://www.sparkfun.com/commerce/product_info.php?products_id=8670
Hi
I very elementary question: Does this then mean that I can charge my battery, with a Li-Po charger of course, with a 5V mini-USB wallwart that came with my cell phone?
Thanks
yes you can charge these batteries on usb power
But use the correct charger or you will be calling the fire dept.
this one will work

Hi
That is the charger I own; I bought it when I bought the batery. What I'm curious about is whether or not a 5v cellphone charger plugged into the mini-USB on the li-po charger is appropriate?
Thanks
Christian
(That is the charger I own; I bought it when I bought the battery. What I'm curious about is whether or not a 5v cellphone charger plugged into the mini-USB on the li-po charger is appropriate?)
yes you can
Motorola chargers are cheap and plentiful
As long as it has mini-usb connector on it
Does this battery have a inbuilt overcharge/overcurrent/discharge protection pcb like the other li-ion batteries or not?
is this thing just always out of stock? ive been waiting a month...
why does this battery not have the specific feature of "Battery includes built-in protection against over voltage, over current, and minimum voltage." that the 1100 mAh and 100 mAh batteries do?
That's a good question. The 2000mAh battery has the same protections listed in the Safety Test section of the data sheet as the 100, 860 and 1100mAh batteries.
Hi..I meet some problems when using lithium polymer battery before. That are self discharge very fast and every battery have different performance (some can use 8 hour but some only 4 hour on some device). Do you meet this kind of problems for this battery? How if i need to buy more than 2 pcs?
