    I have some video equipment i need to power off directly from my
    car's
    battery. I need a wire that is not too big, because i need to solder
    on a special quick-release connector that will be used to easily
    disconnect the cable from my video equipment. The cable requires 2
    wires inside, one for positive and one for negative on the battery.
    The biggest cable i found with 2 conductors, has 2x 22AWG wires
    inside. Some tell me that it is too small and some say it will work
    no
    problem. I don't want the wires to start melting and cause a fire!
    The
    video gear will draw no more than 1 amp total, directly off the car's
    12V battery. My question is, what is the maximum length of cable i
    can
    use to remain safe? Thnks for your advice.
