    Hi all,

    Good morning.I need explanation about the following statements.Can anybody explain me how to calculate the POWER LIMIT for the system from these statements?

    "Power to the system will be provided by four NiMh batteries with a capacity of 2.5 Ampere-Hours per cell.
    system shall run for a minimum of four hours without recharging.
    The battery charger will be powered from an external 9 Volt regulated supply."

    And a happy "good evening" to you from the other side of the world. :)

    The Battery University website has eloquent explanations of ampere hours and battery run times: http://www.batteryuniversity.com/
