Here''s a useful battery pack calculator for calculating the parameters of battery packs, including lithium-ion batteries. Use it to know the voltage, capacity, energy, and maximum discharge
This configuration increases the total capacity (mAh) of the battery pack while keeping the voltage the same as a single cell. For instance, connecting three 3.7V cells with 2000mAh each in parallel results in a 3.7V battery pack with a capacity of 6000mAh (2000mAh x 3). 3. Series-Parallel Connection
Instead, the amount of battery that a user is allowed to access is restricted. This reduced capacity is called the “usable capacity,” or “available kilowatt-hours (kWh)” and is usually 95%-99% of the total available capacity. For instance, a battery that can physically hold a total of 65 kWh may only make available 62 kWh for the car
Watt-hours (Wh): The total energy capacity of a battery pack, calculated by multiplying the voltage (V) by the amp-hours (Ah). Amp-hours (Ah): The amount of electrical charge a battery can supply in one hour, typically used for larger battery packs.
The total, (or gross) capacity of a battery pack is the amount of energy it can store when it''s fully charged to 100% The usable capacity is how much energy the user is allowed to access.

Combine the results for total pack voltage and capacity; Example: Let''s design a battery pack using 18650 cells (3.7V, 3000mAh each) with a 4S3P configuration (4 series, 3 parallel). Voltage calculation: 4 cells in series: 4 × 3.7V = 14.8V; Capacity calculation: 3 cells in parallel: 3 × 3000mAh = 9000mAh (9Ah) Final result: Total pack voltage
Step 3: Calculate the total number of cells: Total Cells = Number of Series Cells * Number of Parallel Cells Total Cells = 7 * 6 = 42 cells So, you would need 42 cells in total to create a battery pack with 24V and 20Ah using cells with 3.7V and 3.5Ah. 1. Why do I need to connect cells in series for voltage?
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.
To calculate the number of cells in a battery pack, both in series and parallel, use the following formulas: 1. Number of Cells in Series (to achieve the desired voltage): Number of Series Cells = Desired Voltage / Cell Voltage 2. Number of Cells in Parallel (to achieve the desired capacity):
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.
When designing a battery pack, cells can be connected in two ways: in series to increase voltage, or in parallel to increase capacity. Series connections add the voltages of individual cells, while the parallel connections increase the total capacity (ampere-hours, Ah) of the battery pack.
