The batteries used in power packs typically discharge (provide power output) at about 3.6V or 3.7V and recharge at 4.2V. (Lithium-ion cells, used for all the packs I tested, charge best at about that rate.) When you see that a battery pack has 10,000 mAh, that’s 10,000 mAh available at 3.6V or 3.7V.
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.
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.
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.
Ensure your batteries are of the same capacity for accurate results. By specifying the number of batteries connected in series, this function will calculate the total voltage output of your battery pack. This feature helps you optimize your battery setup for desired voltage requirements.
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.
