Adafruit Battery Packs Lithium Ion Polymer Battery 3.7V 1200mAh (1 piece)
Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 1200mAh for a total of about 4.5 Wh. If you need a larger battery, we also have a 2000mAh+ model.
The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly.
The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts. However, even with this protection it is very important that you only use a Lilon/Lipoly constant-voltage/constant current charger to recharge them and at a rate of 2A or less (500mA is best). We suggest our Micro Lipo charger, which has a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge.

Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1/2C or even less – 500mA max in this case which is how much you can get from a USB port.
Additional Safety
Do not use a NiMH/NiCad/lead-acid charger. Also, do not abuse these batteries, do not short, bend, crush or puncture. Never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or possibility of short circuits. As with all Lithium ion polymer batteries and with any power source – they should be used by experts who are comfortable working with power supplies
Please note: There are some shipping restrictions when it comes to shipping lithium ion batteries. If anything occurs we will notify you as soon as we are aware of an issue with the order.
