Electricity, at its core, is made up of two (2) components – Voltage, measured in Volts (V), and Current, measured in Amperes (A). Amperes, or Amps, are commonly referred to on a time basis in Amp-Hours (Ah). For example, a battery with a 1Ah capacity should be able to continuously deliver 1A of current to a device for one full hour. This same battery could also deliver 2A of current for 1/2hr (30m), or 1/3A for 3hrs, etc. When you multiple those values together, V x A, you get Power, measured in Watts (W). Similarly, when you multiple V x Ah, you get Power in a time-basis, measured in Watt-hours (Wh). This is the primary unit of measure that we use when discussing battery systems—taking into consideration different battery chemistries and level-sets— in order to have a singular comparison measurement.
