What to pay attention to when assembling 18650

1. The batteries are arranged neatly, which facilitates easy maintenance in the future. It is best to use a standard 18650 battery card holder. 2. The welding is good, and the most common welding method in the market is to use a nickel welder for spot welding. You can also use an electric soldering iron, and the soldering points are in good contact. 3. After soldering, the lines of each battery group must be cleaned. 4. Waterproof and insulated. It is best to cut a piece of barley paper or use asbestos. 5. The most important point is before welding. The internal resistance of the battery, the current voltage error should not exceed 0.05V! If possible, a special protection board for lithium batteries must be added to guard against overshoot and overdischarge. 6. After welding, measure whether the voltage of each circuit is good or not.
