    Hello,

    Do you mean to switchoff when the battery goes empty ?
    In this thread a circuit is shown by SgtWookie.
    http://forum.allaboutcircuits.com/showthread.php?t=17588

    When you want the circuit to switchoff when a level is reached exchange the two comparator inputs.

    Greetings,
    Bertus
