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.
However, 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.
Sara Macagno, inInternational Journal of Hydrogen Energy, 2004 The battery pack is composed by two lead acid batteries of 24 V each, with an average lifetime of 5 yr. We have chosen 48 V because the power of the systems is limited, and two batteries in series for safety; it represents also the nominal inverter voltage.
A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current. The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles.
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.
A battery pack consists of several mechanical and electrical component systems. It contains battery cells that are characterised by different chemistries, sizes, and shapes. The battery cells are connected in series or parallel configurations to achieve the required total voltage and current levels . Charlotte Roe, ...
EVs Explained: Battery Capacity, Gross Versus Net
Gross Capacity—or Total Capacity—is the total amount of energy a pack can theoretically hold. Net Capacity—or Usable Capacity—is the amount of energy the car can actually draw on to move.

Cell Capacity and Pack Size
You can immediately see that the high capacity 200Ah cell produces a minimum pack capacity ~138kWh at ~800V. The increments in pack capacity are also 138kWh. The small 5Ah cell allows a more granular approach to pack sizes, the downside is the number of cells that are used and hence the complexity of items such as the busbars.
