18650 battery pack 12v

　　18650 lithium-ion battery assembly tutorial

　　The 18650 lithium-ion battery assembly method depends on the battery structure. Different lithium-ion battery pack structures have different methods for PACK assembly. The 18650 lithium-ion battery pack has multiple strings and multiple strings, and attention must be paid to the combination before assembly. The battery capital considers it basic The assembly of the upper battery is very simple, similar to the following 1 string 1 parallel 18650 lithium

　　The battery assembly is the same. The summary and analysis of the 18650 lithium-ion battery pack process skills can start with the simple basic 18650 lithium-ion battery assembly, so that it will be easier to get started in the future.

　　Through the above video teaching of assembling batteries on site, is it very simple to make a series of 1 parallel lithium-ion batteries? Of course, these should also pay attention to the following points.

　　1. The batteries are neatly arranged, which is convenient for maintenance in the future. It is best to use the standard 18650 battery tray.

　　2. The welding is good. The most common welding method on the market is spot welding with a nickel welder, or an electric soldering iron. 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 barley paper or use asbestos.

　　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-ion batteries must be added to prevent overcharging and over-discharging. After welding, measure whether the voltage of each circuit is good.

　　6. After the newly assembled battery pack has been used for a period of time, it is necessary to test the voltage of the battery in groups.
