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.
To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah). Identify the Parallel Configuration: Count the number of cells connected in parallel.
Calculate the total voltage by adding the voltages of batteries in series. Calculate the total amp-hour capacity by summing amp-hours in parallel. Multiply total voltage and amp-hour capacity for total watt-hours. Example: A 200Wh battery running a 50W device has a run time of 4 hours (200 ÷ 50).
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
