18650リチウム電池を使用していることをご存知ですか?

At present, whether it is laptops, walkie-talkies, portable DVDs, instruments, audio equipment, model aeroplanes, toys, cameras, digital cameras, drones, outdoor lighting, door control, sprayer, medical instrument … and other motor equipment, 18650 lithium batteries are needed.

What is an 18650リチウム電池 pack?

18650 refers to the appearance specifications of the battery, where 18 means the diameter is 18mm, 65 means the length is 65mm, and 0 means it is a cylindrical battery. At present, lithium batteries can be divided by NCM(Ternary Lithium Battery) and LiFe PO4 due to different materials. The nominal voltage of a single cell of an NCM battery is 3.6V, and the maximum capacity can reach 3500mAh, while the nominal voltage of a single cell of a LiFe PO4  battery is 3.2V, and the maximum capacity can reach 2000mAh. The 18650 lithium battery pack is assembled by welding one or more 18650 cells in series and parallel.

How to create a custom 18650 バッテリーパック for high-performance applications?

So why do we need to assemble? To correctly match the device in life, we often use battery assembly, which can improve the battery’s capacity, energy density, and key performance indicators such as power voltage and current by optimizing the internal structure and composition of the battery. So to start making your custom battery pack, it is important to consider the specific requirements of the battery application, including voltage, capacity, and discharge current.

In short, a single 18650リチウム電池 often needs to be assembled and then used in the device. We can’t live without light in our lives, and we can’t live without places without electricity and the Internet, so batteries are very important to each of us, but how to use and how to customize the battery pack still need to follow the manufacturer’s advice to avoid unnecessary harm.
