A 48V 20Ah battery has a total energy capacity of 960 watt-hours (Wh), calculated by multiplying its voltage (48 volts) by its amp-hour rating (20 Ah). Understanding this capacity is crucial for determining how long the battery can power devices and for selecting the appropriate battery for various applications.
What does a 48V 20Ah battery represent?
A 48V 20Ah battery indicates that the battery operates at a nominal voltage of 48 volts and has a capacity of 20 amp-hours. This means:
- Voltage: The electrical potential difference, which determines how much power can be delivered.
- Amp-Hours: A measure of the charge capacity, indicating how long the battery can supply a certain current.
The combination of these two specifications provides insight into the total energy storage capability of the battery.
