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.
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.
Modules are designed to balance the load and extend the life of individual cells by ensuring optimal performance. Finally, the battery pack is the top-tier component incorporating multiple battery modules. It's the ultimate package, ready to power larger devices such as electric cars, smartphones, or even renewable energy systems.
