    To many volts?

    Hi gang. I am getting a starter that says it can handle 12 to 18 volts.
    would a LiFe 19.8 Volt hurt the Starter buy just being 1.8 volts over?

    http://www.hobbyking.com/hobbyking/s...arehouse_.html

    There is also another type that is 16.6 volts as well that I could get. I thought about running two 7.2 in series but found these other one's
    So why bother with two battery's? or does running them like that give you a better option?

    Thanks for any help.

    RE: To many volts?

    I would say it would be fine using the life. Amps not volts is the big killer ad the starter will draw the amps it requires.

    RE: To many volts?

    Another Question as I am still confused a bit LOL
    Like the above 19.8 volt $$$ and these below are a bit cheaper

    This starter I am getting is a 6.1 geared ratio. from 12 to 18 volts.

    So I am also looking at the LiFe 4200 MAH @ 30C @ 13.2 volts
    and also the LiFe 4200 MAH @ 30 C @ 16.5 volts.
    So what Will the diff be between all 3 of these for a days use? or power ?
    Would I be just fine with the lesser volts?
    Or maybe the better thing to do, is ask what one would you use?

    Not sure if I am even asking my question right. [] Sorry.

    RE: To many volts?

    The higher voltage you supply to a DC motor the faster it spins and the more current drawn. More current less battery life. All your batteries have the same capacity. Seriously - anything you've listed should work. I'd use the highest "C" rated batteries with the highest capacity that will physically fit and stay within the voltage rating of the motor. I never like to push voltage limits.

    RE: To many volts?

    Also, remember that the nominal voltage for a lipo (3.7V per cell) is when it's almost outa gas. You should really make your choice based on the fully charged voltage. A 4S pack is 16.8 fully charged, so a good choice for this application, a 6S pack would be 25.2V! Spin baby spin!!! Also, since that's a geared starter, you may even be good on 3S.
    As John said, the lower the voltage that's able to do the job, the longer your starter will last.
    Cheers,
    Pete

    Thanks Pete,
    So I think I will go with this one then?

    Good Choice? Remember the starter is already geared at 6.1
    this one is at 16.5 volts ( 30C constant and 40C burst )

    not really 16.5V, but actually 21V fully charged. Don't be misled by the nominal voltage rating of batteries
