(1) Large capacity. The capacity of 18650 lithium ion battery is generally between 1200mAh and 3600mAh, while the capacity of general battery is only about 800MAH. If they are combined into the 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack can easily exceed 5000mAh

(2) Long service life. 18650 lithium ion battery has a long service life. In normal use, the cycle life can reach more than 500 times, more than twice that of ordinary batteries

(3) High safety performance, 18650 lithium ion battery has high safety performance, no explosion and no combustion; Non toxic, non polluting, ROHS trademark certification; Various safety performances are completed at one time, and the number of cycles is greater than 500; It has good high temperature resistance, and the discharge efficiency reaches 100% at 65 ℃. In order to prevent short circuit of the battery, the positive and negative poles of the 18650 lithium ion battery are separated. Therefore, the possibility of short circuit has been reduced to the limit. The protective plate can be installed to prevent the battery from overcharging and discharging, thus extending the service life of the battery
