　　The 18650 lithium-ion battery is one of the most common lithium-ion batteries currently on the market, so what are the key points about the PACK process of the 18650 lithium-ion battery? Let's take a look below.

　　The 18650 lithium battery pack process is mainly formulated according to the PACK battery structure. Most of the 18650 lithium battery pack process features are similar, and its characteristic is multiple parallel strings. The 18650 lithium battery pack process has distinct characteristics, the biggest feature of which is the flexible combination. Most continuous orders can be completed semi-automatically. It is conceivable that the 18650 lithium battery pack process is becoming more and more streamlined now. Generally, 18650 lithium battery PACK battery pack includes: 18650 batteries, battery protection board, connecting nickel sheet, leading nickel sheet, green paper accessories, insulating paper, wire or plug wire, PVC outer packaging or shell, output (including connector), key switch, The power indicator, and auxiliary materials such as EVA, barley paper, and plastic brackets together form a PACK, and most types of 18650 battery PACKs are suitable for this process.
