Customer ServiceHowever, all of this takes time and hence please use this as a first approximation. The battery pack mass is roughly 1.6x the cell mass, based on benchmarking data from >160 packs. However, there are a number of estimation options and always the fallback will be to list and weigh all of the components.
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.
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.
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.
This battery pack calculator is particularly suited for those who build or repair devices that run on lithium-ion batteries, including DIY and electronics enthusiasts. It has a library of some of the most popular battery cell types, but you can also change the parameters to suit any type of battery.
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):
