You need to know the current and the time to calculate the lithium-ion battery capacity. The current, usually measured in amperes (A) or milliamperes (mA), is the amount of electric charge that flows through the battery per unit of time. The time, usually measured in hours (h) or fractions of an hour, is the charge or discharge cycle duration.
Lithium battery capacity is typically measured in ampere-hours (Ah) or watt-hours (Wh), indicating the amount of charge it can hold. Common capacities vary based on application but range from small batteries at a few Ah to large storage batteries of several hundred Ah. What is the usable capacity of a lithium battery?
Perform the Calculation: Divide the maximum continuous discharge current by the nominal capacity to determine the “C” rating of the battery. Example Calculation: Suppose we have a lithium-ion battery with a nominal capacity of 2000mAh and a maximum continuous discharge current of 10A. To calculate the “C” rating: C Rating = 10A / 2Ah = 5C
Don’t allow the battery voltage to drop below 3.0V as it can damage the battery Lithium batteries will often have a specified maximum discharge current of say 2C, which means 2x their mAh rating.

Maximum discharge current : 1C. That means that it is rated to provide 250mA of current. As always, voltage can be raised by putting cells in series (but watch out for balancing issues), and current can be raised by putting cells in parallel. If both must be raised then a full array of cells must be used.
