battery 18650 rechargeable.How to assemble 60V battery pack from 18650 lithium battery?

　　Sports DV rechargeable batteries generally have internal short-circuit faults and external short-circuit faults. Generally, it is easy to occur during the entire battery charging process. Poor charging electrode chip can also cause short circuit failure. If the lithium-ion battery is used in an ultra-low temperature natural environment, or below 4℃, and the cost-effectiveness of the lithium battery protection board is not high, basically few people will match each 18650 lithium battery protection board, usually after A series of lithium battery protection boards are maintained as a module. In fact, only this module is maintained in series, and each module cannot be truly maintained. In order to increase the capacity of lithium-ion batteries, there are currently about 2,500 lithium-ion batteries on the market out of 18,650. Sports DV rechargeable batteries will also find that the use of rechargeable batteries has been reduced, and some original lithium-ion batteries do not even charge in the ultra-low temperature environment of mobile phones. But don't worry too much, this is just a temporary situation, different from using high temperature natural conditions. Once the temperature rises, the rechargeable battery's molecular structure heats up and returns to its previous consumption. Traditional liquid lithium batteries use flammable organic solvents and polyolefin separators. Generally, the single resistance of 18650 is around 70m ohms. If there are too many battery series, the internal resistance will naturally increase with the increase of the series. On the contrary, the internal resistance of the series will increase as the series increases. Large, the greater the power, the higher the efficiency, the higher the natural temperature. If the temperature is higher than a certain value, the lithium battery will be destroyed.
