What is the capacity of the 18650 lithium-ion battery?

The battery pack should be customized according to the product. If the product is medium to high-end, the battery can be imported from big brands (original), because there are many small domestic battery factories that have false standards. If the price is too sensitive (such as Strong light flashlight product price competition is relatively high), you can choose a regular domestic manufacturer of 2200mah~2600mAh batteries or perhaps a lower 1500+ capacity. 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 cells. These indicators are all very important. . It is worth noting that many buyers have a misunderstanding that the actual discharge current will be large when the capacity is high, but this is just the opposite: generally divided into capacity type and rate type, the capacity type mainly represents large capacity, but the discharge current is generally low At 1C, the current is small; the rate type can discharge at a large current, but the capacity is low and the operating time is not long. This is similar to not having both fish and bear's paws. How can we understand the practical capacity of 18650 lithium-ion batteries? The labeled capacity of unscrupulous manufacturers, but you can’t believe it. If you want to know the actual capacity, you have to conduct a charge and discharge test through professional testing equipment. Therefore, most people don’t know the detailed capacity when they get it. It is easy to be cheated by the seller. Buyers really feel that the capacity is strange, and they can ask the supplier to issue a test statement or choose a third-party professional test organization statement. Finally, the price of 18650 lithium-ion batteries is proportional to the size of the capacity. The larger the capacity, the greater the energy ratio, and the more materials used, so the price will be more expensive. The general price is 10~30 yuan/piece.
