Customer ServiceTo 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.
This battery pack calculator is particularly suited for those who build or repair devices that run on lithium-ion batteries, including DIY and electronics enthusiasts. 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.
To calculate the runtime of a battery pack, you need to know the device's power consumption. Power consumption is typically measured in watts (W). Calculate the Total Energy Capacity: This is done by multiplying the total capacity by the total voltage.
Lithium-ion batteries, particularly the 18650 battery pack design, have become the industry standard for many applications due to their high energy density and long lifespan. Understanding how to calculate a lithium-ion battery pack's capacity and runtime is essential for ensuring optimal performance and efficiency in devices and systems.
Therefore, the lithium battery must also be about 58v, so it must be 14 strings to 58.8v, 14 times 4.2, and the iron-lithium full charge is about 3.4v, it must be four strings of 12v, 48v must be 16 strings, and so on, 60v There must be 20 strings in parallel with the same model and the same capacity.
