    What is the maximum capacity of 18650 lithium battery?

    Because the size of 18650 battery is fixed, 18 represents diameter, 65 represents height and 0 represents cylindrical shape. The maximum capacity of 18650 lithium-ion batteries is still a question worth discussing. Therefore, it has been concerned by many practitioners. In recent years, the technology of various manufacturers in China has been improved. The capacity of 18650 lithium-ion batteries with a capacity of more than 3500 mAh has been gradually improved. But the stability of 18650 lithium-ion batteries with a capacity of more than 3500 mAh has been achieved in the laboratory. The consistency is not good, and the trend of mass production can not be formed for the time being. If someone says that someone whose home has 3500,4000 mAh is deceptive, you can see the price. At present, the large capacity 18650 lithium batteries bought in batches on the market are 2950 mAh, which is also called 3000 mAh. At present, 2200 mAh-2600 mAh capacity range batteries are relatively stable and mature in all aspects of technology. If it is to do batteries, it is better not to use high capacity batteries, whether from the cost-effective or the service life of batteries after grouping, it is not a cost-effective solution, so the higher the capacity of the batteries, the more unstable the use of the batteries.

    Battery packs need to be customized according to different product uses in different working environments and fields. If the product belongs to medium and high grade, then the battery can choose imported batteries of large brands such as Sanyo, Panasonic, etc. There may be some false marks in the batteries produced by many small-scale domestic battery manufacturers. If the price is too sensitive, the normal domestic manufacturers such as Biao can be selected. The 1800 mah-2600 mAh capacity batteries produced by Yadi and GEB Energy. Most applications have different current and time requirements, so most of the power supply batteries are presented as battery packs. Consideration should be given to the consistency, stability and safety of the batteries in the selection of battery packs. Moreover, each battery in each battery group should be matched in all aspects, such as the same voltage, the same internal resistance and the same capacity. These indicators are very important.
