　　18650 lithium battery assembly method

　　1. The 18650 lithium battery packs are neatly arranged, which is convenient for maintenance in the future. It is best to use a standard 18650 battery card tray;

　　2. The welding is good. The most common welding method on the market is spot welding with a nickel welding machine. An electric soldering iron can also be used, and the solder joints are in good contact;

　　3. After welding, the lines of each battery group must be clear;

　　4. Do a good job of waterproofing and insulation. It is best to cut a piece of highland barley paper or use asbestos material;

　　5. The most important point is that the internal resistance of the battery before welding, and the current voltage error should not exceed 0.05V! If possible, a special protection board for the 18650 lithium battery pack must be added to prevent overcharging and overdischarging;

　　6. After welding, measure whether the voltage of each circuit is good;

　　7. After the newly assembled lithium battery pack has been used for a period of time, the voltage of the battery should be tested in groups.
