Parallel Connection: Increases the battery pack’s capacity, essential for storing the energy required to achieve the desired range. To calculate the gross battery pack size, multiply the total parallel capacity in ampere-hours (Ah) by the battery pack’s nominal voltage in volts (V). The result is in watt-hours (Wh).
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 way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.
Also, with a 200Ah cell it is not possible to make a pack with a total energy between 75 and 125kWh. This is perhaps easier to visualise graphically if we plot the total energy of the pack versus the parallel string capacity in Ah.
Repeating this calculation with a 200Ah cell and the same ~400V pack requirements shows that the smallest total energy for the pack is 69kWh. Also, the increments are 69kWh for each increase in the number of cells in parallel. This could be a very cost driven pack design, but is not so flexible in total capacity.
Lithium battery capacity is typically measured in ampere-hours (Ah) or watt-hours (Wh), indicating the amount of charge it can hold. Common capacities vary based on application but range from small batteries at a few Ah to large storage batteries of several hundred Ah. What is the usable capacity of a lithium battery?

How to compare mAh and Wh
Simply put, Wh, or Watt-hours, is the measure of voltage * Amp-hours. In the case of the batteries you''re looking at, you typically see mAh as the quoted battery capacity figure. So, for example, a typical AA Ni-MH rechargable battery has a nominal cell voltage of 1.2V. If you find one with a capacity of 2,000mAh, it would have a 2.4Wh rating.
