Working out how long you can run when you know the power and the capacity
Use this form to calculate how many hours you could run for given the power you require and the batteries you have. To do this you need to know the voltage of your system (defaults to 12v), the power requirements of your system, and the charge capacity (in ampere hours) and manufacturer's recommended maximum discharge amount (defaults to a conservative 50%) of your battery array.System power: Watts (W)
Battery capacity: Ampere-hours (Ah)

Working out how what battery capacity you need to run yer amp for so many hours
Use this form to calculate what battery capacity (in Ampere-hours, Ah) you'll need to run your power amp for a certain number of hours. To do this you need to know the voltage of your system (defaults to 12v), the power requirements of your system, and how long you'll want to run for. The calculator defaults to a manufacturer's recommended maximum discharge amount (defaults to a conservative 50%) of your battery array.System power: Watts (W)
