This is a 18650 Lithium Ion Battery Cell manufactured by Cham. It provides high current output in a small form factor. These round high capacity cells have been mainly used in flashlight type applications but with its capability to be used as a drop-in rechargable cell at 3.7V with a capacity of 2600mAh. This is a great battery option for those of you who need a simple to install and replace cell with a lot of juice. This battery can supply 1A of current continuously for roughly 2 and half hours! This makes it best to power portable circuits, robots, etc.We also sell compatible holders and chargers.
The peak current you can draw is a little over 2 Amps. Note that these batteries are not designed to sustain such high loads, we suggest keeping any constant current draw under 1A.
These 18650 Cells have a standard discharge current of 0.2C to a maximum of 2C and can handle about 300 charge cycles.
Note: Due to shipping restrictions, batteries are shipped only by surface courier with a delivery time of 2-7 days. All orders which include batteries will be shipped by surface courier.

However, even with its inbuilt protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 0.5C (2.2A) or less.
Additional safety notes: 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. Polarity matches all Adafruit LiPoly/LiIon chargers and boards, other brands may have reverse polarity and can destroy your battery. 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.
