The formula for calculating battery storage capacity is relatively straightforward and involves multiplying the battery voltage by the amp-hour (Ah) rating of the battery.
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.
The voltage of a battery pack is determined by the series configuration. Each 18650 cell typically has a nominal voltage of 3.7V. To calculate the total voltage of the battery pack, multiply the number of cells in series by the nominal voltage of one cell.

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.
Battery pack mass estimation is a key parameter required early in the conceptual design. There are a number of key reasons for estimating the mass, one of the main ones being the significant percentage it is of the overall mass of the complete system. This calculator uses benchmark data to estimate the mass of everything other than the cells.

The usable energy (kWh) of the pack is fundamentally determined by: Energy (kWh) = S x P x Ah x V nom x SoC usable / 1000 Note: this is an approximation as the nominal voltage is dependent on the usable window. Also, the variation in cell capacity will be needed to be understood to establish accurate pack capacity values in production.
