Identify the Parallel Configuration: Count the number of cells connected in parallel.
Since most batteries have a low ampere hour ratings, they are rated in milliamperes per hour (mAh), one thousandth of an ampere hour (Ah). Since a milliampere hour is one thousandth of an ampere hour, divide 4,400 mAh by 1000 to get ampere hours (Ah). Batteries and cells above these limits must conform to Section I requirements, ship as Class 9.
Battery capacity is measured in ampere-hours (Ah) and indicates how much charge a battery can hold. 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).
A Lithium Ion battery's published rated capacity is the capacity of the cell when the load current is one fifth of the rated capacity (the C Rate). When the current varies from C/5, the capacity will change due to chemical reaction rates including a chemical effect called concentration polarization.
The voltage level of the battery determines the maximum electrical power which can be delivered continuously. Power P is the product between voltage U and current I : The higher the current, the bigger the diameter of the high voltage wires and the higher the thermal losses.
The capacity of lithium-ion batteries can be reduced by as much as 25% at high current (C rating) and operating temperature as compared to their published capacity. Manufacturers typically publish the the capacity when the load is C/5 or one fifth of the rated capacity.
