So a battery with 3 cells in parallel and 2 cells in series is referred to as 3P2S. This battery has 6 cells in it with 3 in paralled, and 2 of those parallel groups in series. It has 2x the voltage and 3x the capacity of a single cell. 2S3P 3P2S The order of the P and S designations in the battery can mean different things.
The 3p3s battery pack is quite simple to visualise. Here we see the 9 cells with connections made to bring them together in parallel and then 3 rows connected in series. This basic principle of series and parallel can be extended to any numbers you wish to create. The diagram below shows the basic principles.
By configuring these several cells in series we get desired operating voltage. Also the Parallel connection of these cells increase the capacity which directly increase the total ampere-hour (Ah) rating of the battery pack. The single-cell configuration is the simplest battery pack.
Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2 shows a battery pack with four 3.6V Li-ion cells in series, also known as 4S, to produce 14.4V nominal. In comparison, a six-cell lead acid string with 2V/cell will generate 12V, and four alkaline with 1.5V/cell will give 6V.
When assembling large battery packs it is necessary to connect cells in series and parallel. Actually the normal method is to assemble them in parallel groups and then to assemble these groups in series. Firstly it is worth remembering what is meant by parallel and series.
In most pack designs the cells are connected in parallel blocks (when P is greater than 1) and then in series. This is an important factor in managing the battery configuration. However, we will also discuss connecting series strings of cell in parallel as a separate article.

Let''s consider a simple example with two batteries connected in series. Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B also has a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage would be 12 volts, and the total current would remain at 2 amps.
