18650 Battery Pack

The lithium 18650 battery pack is one of the most popular lithium-ion battery packs available today. The battery pack powered by the 18650 battery, it is very reliable and boasts an excellent cost per kilowatt hour. The lithium-ion cell classified by its 18mm x 65mm size, which is slightly larger than a AA battery. 18650 Li-ion batteries are the battery of choice when designing for higher voltage and current requirements. Li-ion battery pack has easier assembly, higher energy density, variable size, difference rate for all electrical equipement and energy storage.

Advantage of 18650 battery pack

1. Large capacity

The capacity of the 18650 lithium ion battery pack is 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 life

Lithium 18650 battery pack has a long life. The cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.

3. High safety performance

The 18650 lithium battery has high safety performance. In order to prevent the battery from short-circuiting, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced. A protective board can be installed to avoid overcharge and overdischarge of the battery, which can also extend the service life of the battery.

4. High voltage

The voltage of 18650 lithium battery we provide including 3.7V, 7.4V, 11.1V, 14.8V, 18.5V and 22.2V. which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries.

5. 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 polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of  polymer batteries 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 meet the international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace nickel-hydrogen batteries.

7. Combined in series or parallel to form a 18650 lithium battery pack

8. Wide range of use

Electric vehicles, notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras, consumer electronics and other electronic device.
