The higher the current, the more work it can do at the same voltage. Power = voltage x current. 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.
In conclusion, the power output of a battery is influenced by both its voltage and its ampere-hours rating. A higher voltage allows for greater power output, while a higher amp rating allows for the delivery of a higher current. Understanding these factors is essential when selecting the right battery for your device or application.
Voltage is an important factor that determines the power output of a battery. Higher voltage batteries generally have more energy and can provide a stronger current. On the other hand, the current rating of a battery is a measure of the flow of electrical charge. It is often expressed in ampere-hours (Ah) or amps (A).
It is likely that the voltages are different by design / intentionally. A higher DC voltage enables power to flow with less current (compared to the lower 10.2 Volts). This can be important when pushing DC power through appreciable distances. Battery and voltage is stepped down to 5 or 3.3.
While amps determine the amount of current a battery can supply, volts dictate the force behind that current. When the current remains constant, increasing the voltage will result in a higher power output. Conversely, reducing the voltage will decrease the power output.
Using a battery with a lower voltage rating may result in insufficient power supply, while using a battery with a higher voltage rating can potentially damage the device. In terms of efficiency and energy consumption, a higher voltage battery can deliver more power while drawing less current, which results in reduced energy losses.
