6 FAQs about [How to change the battery pack capacity]

How do you calculate the number of cells in a battery pack?

To calculate the number of cells in a battery pack, both in series and parallel, use the following formulas: 1. Number of Cells in Series (to achieve the desired voltage): Number of Series Cells = Desired Voltage / Cell Voltage 2. Number of Cells in Parallel (to achieve the desired capacity):

How many cells do I need to create a battery pack?

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? Connecting cells in series increases the overall voltage of the battery pack by adding the voltage of each individual cell.

How does a battery pack work?

When designing a battery pack, cells can be connected in two ways: in series to increase voltage, or in parallel to increase capacity. Series connections add the voltages of individual cells, while the parallel connections increase the total capacity (ampere-hours, Ah) of the battery pack.

How to assemble a battery pack?

When assembling a battery pack you should use just one type of cell and balance them before assembling. Note that wiring in parallel cells which are not at the same voltage may make the cells blow up in your face. Not nice. Soldering: Cheaper and easyer for sure, but also a bit dangerous and likely to ruin your cells.

How to complete a battery pack model?

To complete the battery pack model, we need to know how different cell capacities combine to give the overall capacity Q. Going back to our analogy at the start of the post, we can see that the capacity of each cell arrangement in parallel will sum up. But how about those arrangements in series?

How much energy does a battery pack use?

Increasing or decreasing the number of cells in parallel changes the total energy by 96 x 3.6V x 50Ah = 17,280Wh. As the pack size increases the rate at which it will be charged and discharged will increase. In order to manage and limit the maximum current the battery pack voltage will increase.
