E-Textiles Battery - 110mAh (2C Discharge)
This is a very small, extremely lightweight battery based on Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cells outputs a nominal 3.7V at 110mAh but limited to a 2C discharge! 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.
What sets this battery apart from our other 110mAh battery is that fact that it was truly made for e-textiles projects. With no risk to short out and a low current delivery, the E-Textiles Battery will cut off in the range of 240-380mA making this the safest option to power electronics sewn into pieces of fabric.
Battery includes built-in protection against over voltage, over current, and minimum voltage.
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.
- 2C continuous discharge
- Excellent long-term self-discharge rates (<8% per month)
- Robust power source under extreme conditions (-25 to 60C)
- 5.7x12x28mm

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: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Bought hundreds of these batteries to date
We use these batteries in our evaluation product we provide to customers. We bought several hundreds of the batteries to date and didn't experience any issues with them.
Worked great for my project
I powered a golf sweater that included a lilypad arduino, lilypad accelerometer, 5 leds constantly on, and 12 more leds that were powered from time to time (a golf swing meter). The battery did the job for a good portion of the golf outing, longer than I expected. No problems at all (although they're right you need to use pliers to remove the connector). The lilypad USB makes it simple to charge.
wire break easily
The battery itself is good but the wires break easily
small and works great
Great size and good power.
Interesting concept
I found that setting up the charger for it, to quick and easy. But applying it will take time.
Curious what type of "specialized Lithium Polymer Charger" will work. I got 2 of these batteries and couldn't charge them with a LiPo charger from Adafruit (https://www.adafruit.com/product/1944). Could someone please give some examples of suitable chargers?
I bought some of these. I have the SparkFun basic LiPo charger. When I plug in, the light turns off and seems to not charge anymore. Is there a way to find out if it is charging? if not then what charger do I need?I can charge other Lipo batteries just fine. I'm assuming it has something to do with the protection board the battery comes with. Please help
Hello! Most charges are meant to be used with a larger battery than these. You need a charger that can be set for 100mA charging. We carry one that will work with this battery called the Adjustable LiPo Charger. Just set the DIP switch for 100 and you should be all set.
What is the mass of the battery? Unfortunately, it is not in the datasheet.
I bought the SparkFun LiPo Charger Basic - Micro-USB - PRT-10217 - to charge the 110mA battery, but the status light will not go on. When I charge the 400mA LiPo, the status light is on and I presume the battery is charging. Any suggestions on how to charge the 110mA battery? I have the USB/microUSB cable connected to a USB port on my laptop, which tech support said should work.
The regular version of this battery doesn't seem to specify a discharge rate, so it's hard to compare them.
It would not be that surprising to find a 4C or higher discharge rate on the regular ones.
Could you give a value to the extreme lightness? I'm considering to use it on a device attached to a bird - weight really does matter for me.
