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. of.
The 18650 lithium battery has a long service life, and its cycle life can reach more than 500 times during normal use, which is more than twice that of ordinary batteries. 18650 high lithium battery has high safety performance. To prevent battery short circuit, the positive and negative electrodes of 18650 lithium battery are separated. Therefore, the possibility of short circuit has been reduced to the extreme.
Extended information
