From the end of the 20th century to the beginning of the 21st century, the development of the battery industry can be described as "rapid". Lead-acid batteries, nickel-hydrogen batteries and nickel-cadmium batteries have been used until now, and their development time has basically been more than a century. The development of the battery industry is not limited to this, the latest masterpiece is the rise of the lithium battery industry. When it comes to lithium batteries, basically everyone knows a thing or two about it, because we use it everywhere in our lives. Like mobile phones, notebooks, camcorders, etc., digital products like this basically use lithium batteries. Compared with the early nickel-metal hydride batteries, lithium batteries are more durable and have better battery life.

When it comes to lithium batteries, I have to mention the lithium battery protection board, because all the safety indicators of the lithium battery rely on the support of the lithium battery protection board. Moreover, because the parameters of lithium batteries are also different, the types of corresponding protection plates are also different. In layman's terms, lithium batteries generally have a corresponding lithium battery protection board to assist their work. Because the lithium battery needs to work under normal current and voltage, if the instantaneous current is too large due to short circuit or other reasons, it will directly damage the lithium battery cell, and the consequences are very dangerous. . The role of the lithium battery protection board is to avoid a series of unexpected situations such as short circuits, so the parameter requirements of the protection board are also extremely precise. Because its role is to ensure that the working current is kept within a reasonable range at all times, the workmanship of the lithium battery protection board must be very fine. This is why it is said that the protective plates worn by lithium batteries are in one-to-one correspondence. On the other hand, there are many types of lithium battery applications, including conventional, power, energy storage, etc., so the type of lithium battery protection board is also based on the type of lithium battery or lithium battery pack. To design. Therefore, different types of lithium batteries and protection boards cannot be mixed.

I often see on the Internet that some friends combine the old protection board with the new lithium battery because they want to replace the battery or make a lithium battery by themselves. However, afterwards, they find that the newly combined lithium battery does not work properly. , I think everyone has been very clear through the above introduction. And there is another point. The safety of the lithium battery produced in this way is very low, and the lithium battery protection board in it is probably not protective.

Therefore, when we use the lithium battery protection board, we must correspond to it, so that the lithium battery we use can work within a reasonable current value range, not only in terms of safety, but also in terms of battery cells. Certain benefits.
