What is the maximum capacity of 18650 battery
Because the size of the 18650 battery is fixed, "18" represents the diameter, "65" represents the height, and "0" represents the cylindrical shape. How many milliampere-hours the maximum capacity of the 18650 battery can achieve is still a question worthy of discussion. Therefore, it has been concerned by many practitioners. Over the past few years, various manufacturers in China have improved their technology, and continue to experiment and develop their capacity. It has also gradually improved. The laboratory has been able to produce 18650 batteries with a capacity of more than 3500mAh, but the stability and consistency are not good enough, and mass production is not possible for the time being.
Now the large-capacity 18650 battery bought in batches on the market is 2950mAh, and this capacity battery is also called 3000mAh by others. At present, the battery with a capacity range of 2200mAh-2600mAh is relatively stable, and the technology is relatively mature in all aspects. The 18650 battery manufacturer tells you that it is best not to use high-capacity batteries if you are making a battery pack. Whether it is from the perspective of cost performance or the service life of the battery pack after being assembled, it is a very cost-effective solution, so the higher the battery capacity The more unstable it is to use.
The battery pack needs to be customized according to different products used in different working environments and fields. The 18650 battery manufacturer tells you that if the product is mid-to-high-end, you can choose imported batteries from big brands. If you are too price-sensitive, you can choose domestic and regular batteries. 1800mah-2600mAh capacity battery produced by manufacturers. Most application fields have different current and time requirements, so most power supply batteries are presented in battery packs. When choosing a battery pack, you should consider the consistency, stability, and safety of the battery. The 18650 battery manufacturer tells you that there is For each battery in each group of cells, all values must be matched, such as the same voltage, the same internal resistance, and the same capacity. These indicators are very important.
