"18650 lithium battery" is a type of lithium battery.

The capacity of 18650 lithium-ion battery with large capacity is generally between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium-ion battery pack, then the 18650 lithium-ion battery pack is casual It can exceed 5000mah.

Features

Long life The 18650 lithium-ion battery has a long service life. The cycle life can reach more than 500 times during normal use, which is more than twice that of ordinary batteries. High safety performance: 18650 lithium-ion battery has high safety performance, does not explode or burn; it is non-toxic, non-polluting, and has passed RoHS trademark certification; various safety properties are integrated in one go, and the number of cycles is more than 500 times.

It has good high temperature resistance and the discharge efficiency reaches 100 under 65 degrees. To prevent battery short circuit, the positive and negative electrodes of 18650 lithium-ion battery are separated. Therefore, the possibility of a short circuit has been reduced to the extreme. A protective board can be installed to prevent the battery from overcharging and over-discharging, which can also extend the service life of the battery.
