With the rapid development of science and technology, there are more and more lithium battery products in our lives, and various battery accessories have emerged as the times require, such as power type, capacity type, etc., and their functional characteristics are indistinguishable for a while. As a leading manufacturer of 18650 batteries in China, most of the current lithium battery products use 18650 lithium batteries, and we are obliged to share more knowledge about 18650 lithium batteries.
The voltage of a normal battery is 3.6V to 4.2V. Why are there different voltages? In fact, the main reason is that the calculation methods are different. 3.6V refers to the normal discharge platform voltage during voltage use, or the typical voltage, while 4.2V is the fully charged voltage, so these two voltages are actually the same battery, and there is no difference.
18650 lithium batteries on the market are divided into capacity type and power type lithium batteries. The capacity type generally supports a low discharge rate, and is mainly used for lithium battery products with low power consumption such as power banks and flashlights that are often used in our daily life.
The power type, as the name suggests, will be more powerful, so it supports a higher discharge rate, which is used more in our daily household appliances, such as wireless vacuum cleaners, lithium electric drills, electric vehicles, etc. High power consumption Lithium battery products, etc.
Considering the cost, first parallel and then series. For example, when making 12.6V, you can connect N 18650s in parallel, and three groups in series. Only one protection board is needed. May explode during discharge or charge. Sadly, this is the solution most lithium-ion vehicles use today.
From the safety point of view, first serial and then parallel, such as 12.6V, 3 series are used for one protection board, the superimposed capacity is the number of superimposed strings, and as many series, as there are as many protection boards, of course, there are 3S with as many A protections as one. plate. In this way, each series has overcurrent protection and charge equalization, and the probability of discharging or charging explosion is greatly reduced. In fact, the cost of the multi-series integrated protection board is not much higher, but the safety is greatly increased.
The capacity of 18650 lithium battery is 1200-3600mAh, and the capacity of most 18650 lithium batteries on the market is 2950mAh, so it is also called 3000mAh battery. In the laboratory, the maximum 18650 lithium battery can reach more than 3500mAh, but in the current technology, 2200~2600mAh is still the most stable, so the higher the capacity, the better.
In theory, the bigger the better, but not in actual use. The reason is the limitation of technology. When the capacity is larger, the technical requirements are higher, and the technology is less mature, so the stability of the battery with a large capacity may become worse. If you choose a 18650 lithium-ion battery, it is generally better to choose a battery below 3000mAh, and do not blindly pursue high capacity.
