　　The first thing to talk about is the DIY battery pack using 18650 lithium battery

　　18650 lithium battery DIY battery pack is to use different numbers of 18650 lithium batteries in series or in parallel to make it reach the desired voltage or capacity.

　　If you want to assemble a battery pack, you need to pay attention to the following points:

　　1. The batteries are neatly arranged, which is convenient for maintenance in the future. 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. You can also use a soldering iron, the solder joints are in good contact evenly

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

　　4. Do a good job of waterproofing and insulation, using cut barley paper or asbestos material

　　5. The most important point is the consistency of 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 battery pack has been used for a period of time, it is necessary to check the voltage of the battery pack in groups
