The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device.
In the simplest terms, a battery’s capacity describes how many electrons it can store for later use. A battery’s capacity does not tell you the amount of energy it stores or the driving range it can deliver. Even with good capacity, it’s not possible to know how much energy the battery stores without knowing the voltage.
Battery capacity indicates how much energy a battery can store, while voltage determines the power output. Together, these factors influence the performance and longevity of batteries in various applications. What are watt-hours (Wh), and how do they relate to battery performance? What is battery capacity, and why is it important?
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
The way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.

Capacity influences how long a battery can power a device, while voltage determines how much power it can deliver. By balancing these two factors and considering the specific requirements of your application, you can select a battery that provides optimal performance, longevity, and safety.
5MW (power) 5 MWh (capacity) - 1C; 5MW/10 MWh - 0.5C; The C-rate is meant to be specified in conjunction to a battery''s energy storage capacity. With it, you should be able to calculate the maximum charging or discharging power given the storage capacity, i.e. maximum power in MW = storage capacity in MWHr x C-rating.

The simple method (power adequacy) consists in ensuring the power equilibrium between power sources and loads using the battery system as an adjustment variable. The complex method takes power system dynamics into account and consists in identifying the minimum battery capacity that satisfies power quality constraints.
The Interrelation between Voltage and Capacity Another crucial aspect of battery performance is the relationship between voltage versus capacity. Although increasing the voltage can enhance operational power delivery efficiency and even make a lot of changes, it is only the capacity that determines the length of time the device can be operated ...
