1. The batteries are neatly arranged, which is convenient for maintenance in the future. Best to use a standard 18650 battery card tray
2. Good welding, the most common welding method on the market is spot welding with nickel welding machine. You can also use a soldering iron, the solder joints are in good contact
3. After welding, the lines of each group of batteries 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 lithium batteries 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 battery pack has been used for a period of time, it is necessary to check the voltage of the battery in groups
