  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.
