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.
Both of these designs have strengths and weaknesses. Hence both have places where they are optimal. Parallel and then series will be the lowest cost, but least flexible. Series and then parallel gives flexibility and redundancy and hence is often found in large battery packs.
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.
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.
Firstly it is worth remembering what is meant by parallel and series. Cells that are in parallel have the positive terminals all connected together and the negative terminals all connected together. The voltage of the group of cells in parallel will be the same as a single cell.
Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of a combination of series and parallel connections. Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve a nominal voltage 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh.

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.
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.
How should you connect battery cells together: Parallel then Series or Series then Parallel? What are the benefits and what are the issues with each approach? The difficulty with this is the BMS operation with packs in parallel. Each of the large 70kWh sub-packs needs to have it''s own BMS and full set of sensors and HV protection.
The most common configuration for EV batteries is a series-parallel hybrid. In this setup, multiple cells are connected in series to increase the battery pack''s voltage, and multiple groups of series-connected cells are then connected in parallel to increase the battery pack''s overall capacity.
lithium-ion batteries are widely used in high-power applications, such as electric vehicles, energy storage systems, and telecom energy systems by virtue of their high energy density and long cycle life [1], [2], [3].Due to the low voltage and capacity of the cells, they must be connected in series and parallel to form a battery pack to meet the application requirements.
Lithium-ion power batteries are used in groups of series–parallel configurations. There are Ohmic resistance discrepancies, capacity disparities, and polarization differences between individual cells during discharge, preventing a single cell from reaching the lower limit of the terminal voltage simultaneously, resulting in low capacity and energy utilization. The effect …

two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah). four 1.2 volt 2,000 mAh wired in parallel can provide 1.2 volt 8,000 mAh (2,000 mAh x 4). But what happens if you wire batteries of different voltages and amp hour capacities together in parallel?
How Wiring in Batteries in Series & Parallel Affects Voltage & Capacity. Wiring batteries in series sums their voltages while keeping their amp hour capacity the same. Wiring two 12V 100Ah batteries in series gives you a 24V 100Ah battery bank. 12V + 12V = 24V . Wiring batteries in parallel sums their amp hour capacities while keeping their voltage the same. …
