What is the maximum capacity of 18650 lithium battery?

Since the size of the 18650 battery is fixed, "18" represents the diameter, "65" represents the height, and "0" represents the cylinder. 18650 lithium battery capacity biggest can do how many mah, a problem is a very worth exploring, therefore has been attracting the attention of many practitioners, the various manufacturers and technology of China for the last few years have improved, unceasing experiment research and development, capacity also gradually improve, laboratory have been able to make more than 3500 mah capacity inside 18650 batteries, but the consistency and stability is bad, temporarily couldn't form production trend. If someone says somebody has 35,000 mAh, 4,000 mAh that's a lie, you can just look at the price. The large capacity 18650 lithium battery bought in bulk on the market now is 2950mAh, and this capacity of the battery is also known as 3000mAh. At present, the capacity range of 2200mah-2600mah battery is relatively stable and the technology is relatively mature. If it is a battery pack, it is better not to use a battery with a high capacity. No matter from the cost performance or the service life of the battery pack, it is not a cost-effective solution. Therefore, the higher the battery pack capacity, the more unstable it will be.

Battery pack need according to different products used in the field of different working conditions and to customize, if the product belongs to high-grade, the battery can choose a big brand import batteries, such as: Sanyo, Panasonic, etc., domestic also has many small-scale production of manufacturer of batteries battery there may be some empty mark, if the price is too sensitive, you can choose domestic formal manufacturers such as BYD, Dongguan Hong wei energy production of battery 1800 mah - 2600 mah capacity. Most applications have different current and time requirements, so most of the power supply batteries in the battery pack, the consistency of batteries should be considered in choosing a battery pack, stability, security, and each set of batteries for each of the batteries, all aspects of value should be matching, such as voltage, internal resistance, same same capacity, etc. These indicators are very important.
