A 48V 20Ah battery has a total energy capacity of 960 watt-hours (Wh). This is calculated using the formula:
Watt Hours Wh =Voltage V ×Amp Hours Ah
Substituting the values:
Wh=48V×20Ah=960Wh
This means the battery can deliver 960 watts of power for one hour, or proportionally less power for a longer duration, making it suitable for various applications such as electric bikes, solar energy storage, and backup power systems.
