18650 assembled into a battery pack should pay attention to what matters?
Install the battery pack also pay attention to short circuit problems, pay attention only to high temperature glue, barley paper, nickel and other accessories, to avoid nickel scraping the battery skin, scratch the skin easily short circuit.
When used in series, the battery voltage, internal resistance, capacity as required, the voltage difference of 20mV, the internal resistance difference of 10 milliohms, the capacity difference of 20mA more reasonable, especially the difference between the internal resistance of the battery in series will cause fever , Serious will cause smoke to fire.
18650 battery regardless of whether the series or parallel into the battery pack on the battery is a certain requirement.
