BU-302: Series and Parallel Battery Configurations
While recommended for safety in a smaller 2- or 3-cell pack with serial and parallel configuration, these protection devices are often being omitted in larger multi-cell batteries, such as those for power tool. The PTC and CID work as expected to switch of the cell on excessive current and internal cell pressure; however the shutdown occurs in

Why are series and parallel batteries popular in lithium battery packs?
Series and Parallel configurations are popular in the lithium battery packs. Because, by combining multiple batteries in different configurations, we can easily achieve our required battery specification for the load requirements. The lithium batteries are good in charge and discharge rates. It is also smaller in size.
What is the difference between a series and parallel battery?
Series Connection: Batteries in Serial adds up the voltage, but current will be same. Parallel Connection: Batteries in Parallel adds up the capacity (mAh) or Current, but keeping the voltage same. Lithium batteries needs to be charged at it’s precise voltage and current specifications. Otherwise, it may damage the battery and can cause fire.
What is a parallel battery setup & how does it work?
