    Hello.
    I require some help for a school project

    Brief:
    i currently have a single, 11.1V LIPO battery.
    i then need to reduce this voltage down (so that it doesnt arc and burn out switch contacts when its repeatadly pulled), and use this small current/voltage loop, to drive the larger 11v /high current loop which in turn drives a motor

    attached is the circuit i would expect to look like, but i have no idea on values

    thanks for your help.
    Keith
