The total battery pack voltage is determined by the number of cells in series. For example, the total (string) voltage of 6 cells connected in series will be the sum of their individual voltage. In order to increase the current capability the battery capacity, more strings have to be connected in parallel.
The battery pack capacity C bp [Ah] is calculated as the product between the number of strings N sb [-] and the capacity of the battery cell C bc [Ah]. The total number of cells of the battery pack N cb [-] is calculated as the product between the number of strings N sb [-] and the number of cells in a string N cs [-].
Fill in the number of cells in series and parallel, the capacity of a single cell in mAh, and the voltage of a single cell in volts (default is 3.7V). Press the “Calculate” button to get the total voltage, capacity, and energy of the battery pack. This calculator assumes that all cells have identical capacity and voltage.
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.
