The 18650 battery is a model of rechargeable battery of lithium of 3.7 volts. These rechargeable batteries are very similar to AA batteries but a little bit bigger size. These 18650 batteries also calling Li-ion batteries. The advantage of these rechargeable batteries is there are very lightweight batteries. Furthermore, have high energy capacity and resistance to discharge. In addition, those can resist many charging cycles.
You can use this kind of 18650 batteries in many electronical devices. From the little ones could be flashlights, lights for bikes to powerful devices such as, drills, electrical cars, electrical bikes, lawnmowers. Also is possible to build battery packs to use for a drone motor, electrical bike, among others.
There are many types of 18650 batteries is distinguished by discharge amps and maximum capacity. When we refer about capacity this one is express in milliamps/hour this indicated us the autonomy of each 18650 battery, being of longer duration the more mAh has these 18650 batteries. The most common capacity of rechargeable batteries is between 2000 mAh and 4000 mAh. When we refer about discharge this one is express in amperes this is the maximum current that can supply the power demand of the device. The capacity of the rechargeable batteries could range from one to others, from 3 A (amps) to 35 A (amps).
Many people ask to us what the meaning is of 18650. The 18 indicates the diameter (18 mm) of 18650 battery in millimeters. Next, the number 65 indicates its length (65 mm). The total length of the 18650 battery with the head and protections.

Use safe, long-life industrial 18650 batteries
18650 has steel shell protection, excellent stability and anti-riot performance, and has no potential safety hazards;
Other products use soft pack batteries, which are easy to bulge and fail. Large capacity has the risk of deflagration.
1. Large capacity
The capacity of 18650 lithium battery is generally between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the 18650 lithium battery pack can easily exceed 5000mAh.
2. Long service life
18650 lithium battery has a long service life, and the cycle life can reach more than 500 times during normal use, which is more than twice that of ordinary batteries.
3. High safety performance
18650 lithium battery has high safety performance. In order to prevent battery short circuit, the positive and negative electrodes of 18650 lithium battery are separated. Therefore, the possibility of short-circuiting has been reduced to the extreme. A protection board can be installed to avoid overcharging and overdischarging of the battery, which can also prolong the service life of the battery.
4. High voltage
The voltage of 18650 lithium battery is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries.
5. There is no memory effect.
It is not necessary to empty the remaining power before charging, which is convenient to use.
6. Small internal resistance
The internal resistance of the polymer battery is smaller than that of the general liquid battery. The internal resistance of the domestic polymer battery can even be below 35mΩ, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. In time, it can fully reach the level of international standards. This polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and has become the most promising product to replace NiMH batteries.
7. It can be combined in series or in parallel to form a 18650 lithium battery pack
8. Wide range of use
Laptops, walkie-talkies, portable DVDs, instrumentation, audio equipment, model aircraft, toys, video cameras, digital cameras and other electronic equipment.
