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.
However, the standard voltages for many lithium-ion batteries are 12, 24, and 48 volts. When cells are connected in series, their voltages add together. For example, connecting four cells in series will yield a 12-volt battery. Wiring eight cells in series will produce a 24-volt battery, and so on.
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.
The voltage of a lithium-ion cell varies depending on the particular chemistry type. The nominal output voltage of a single lithium iron phosphate cell (the type used in Battle Born Batteries) ranges between 3.2 and 3.8 volts. However, the standard voltages for many lithium-ion batteries are 12, 24, and 48 volts.
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.
The inside of a lithium battery contains multiple lithium-ion cells (wired in series and parallel), the wires connecting the cells, and a battery management system, also known as a BMS. The battery management system monitors the battery’s health and temperature.
