Winching with 24 volts?

[Carlos Murphy]

Found a great vid from the Australian's on youtube, hard core off roading.
Unknown to me, their using 24 volts on their winches, anybody here doing that?
"Rocks and Ruts Kirup 4x4 off-road event" on youtube.

Are their winches built for 24 Volts?

It would be easy enough to wire two batteries to provide 24V to the winch. I suspect that the motor would spin twice as fast....and also create twice as much heat, and heat is the enemy of electrical motors. So then you'd have to at least double the cool down period between pulls.

I could maybe see this in a race situation where you need the speed and you're a low buck operation willing to take bigger risks...

Back in the day of 7.2V Makita drills we would often use 9.2V batteries when drilling bigger holes. I didn't see any damage but it wasn't double voltage either.

in electrics doubling the voltage quadruples the power. 24v in a 12v motor usually results in immediate smoke. the motor would have to have a huge overcurrent rating to last long.

I still run my old Meyer 6 volt T-5 Snowplow pumps on 12 volts. The old 6 volt motors had really heavy windings. Today's motors, more than likely, have minimum gauge wiring and would fry.

Could you provide a link and the time frame for the winch.

All of my tractors were originally 6v but have been running 12v just fine in some cases for decades (one was converted to 12v in the mid 60's)

But it isn't like you sit there and run the starters for minutes at a time either...
