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.
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.
This 18650 battery pack calculator is used to determine the optimal configuration of 18650 lithium-ion cells for a specific power requirement. With a 12V battery pack with 10Ah capacity, the calculator would determine how many 18650 cells to connect in series for voltage and in parallel for capacity. Voltage calculation: Capacity calculation:
Step 3: Calculate the total number of cells: Total Cells = Number of Series Cells * Number of Parallel Cells Total Cells = 7 * 6 = 42 cells So, you would need 42 cells in total to create a battery pack with 24V and 20Ah using cells with 3.7V and 3.5Ah. 1. Why do I need to connect cells in series for voltage?
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.
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.
