    Winch operating voltages?

    Hi folks, I’m after some assistance relating to operating voltages while winching.

    Has anybody taken voltage readings while using their electric winch.

    I’m after the lowest battery voltages you might have operated to, while the winch motor is running.

    Any feedback would be appreciated.

    You can tell Im a little bored...

    95 defender
    - running 100A disco alternator.
    - pair of 700CCA Century MarinePros, 3 months old.
    - in direct parrallel 2B&S cable about 8cm long.
    - "Tigerz 12000lb" winch 4.6hp I think.
    - Voltage measured by EMS2 gauge.

    voltage at idle - 13.6V
    voltage winching no load - 12.5V
    voltage winching through vehicle brakes "almost stall" - 11.8V

    raising engine speed to at a guess 3000rpm - 13.6V
    when winching no load - 12.6V
    when winching with load "almost stall" - 12.0V

    engine off after maybe 1 minute of winching - 12.5V
    when winching no load - 10.8V
    winching with load "almost stall" - 10.0V and falling so I didn't persevere?

    Voltage came back up to 12.5V and engine started fine.

    Hope that helps, obviously lots of variables in this but??? Any other tests or variables you want measured, fender is lined up on the hill out front near the power pole!

    They are always connected.
    I have them parralled using short lengths of 2B&S. Sit side by side under the seat.
    Engle will run for a couple of days no dramas and if Im camping longer without moving chances are we will have the gennie or at worse use the 2.5L turbo powered generator

    I use to run a DBS but gave up on all the extra wiring and loss of performance.
    Two MarinePros in parrallel gives a good amount of winching grunt and keeps the beer cold - its not that hard to look at the voltage to see if they are getting down abit.
    All other DBS (until you go to triple systems) are either a compromise for the fridge or for the winch IMO.

    If you want I can easily fiddle a few wires and repeat the above using just the one battery?

    Thanks Steve and yes, if you have the time I’d love the feedback.

    cheers, Tim.

    PS, I'll send you a PM in the morning

    Okay,
    so here is the go with just the one MarinePro 700CCA being used.
    all other factors the same...

    voltage at idle - 13.5V
    voltage winching no load - 11.8V
    voltage winching through vehicle brakes "almost stall" - 11.0V

    raising engine speed to at a guess 3000rpm - 13.6V
    when winching no load - 12.0V
    when winching with load "almost stall" - 11.2V

    engine off after maybe 1 minute of winching - 12.4V
    when winching no load - 10.2V
    winching with load "almost stall" - 10.0V and falling so I didn't persevere?


    I might go hook that second battery up - it certainly gives more grunt
    Adios
