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.
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
Batteries achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage potential to derive at the total terminal voltage. Some packs may consist of a combination of series and parallel connections.
If you put batteries in parallel, you increase their maximum current proportionally, without changing the voltage. If you put them in series - you increase the voltage, without changing the maximum current. That's much of a theory. – Eugene Sh. I think you're misunderstanding what the C rate is.
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2: Series connection of four cells (4s). Adding cells in a string increases the voltage; the capacity remains the same. High voltage batteries keep the conductor size small.
