Winching with dual batteries

[NavyDiver]

Winch power isolator or not (http://www.aulro.com/afvb/recovery/153001-winch-power-isolator-not.html)showed Deno with a nifty trick getting his dual batteries to run his winch. Another thread in the D3 section about a flat battery (http://www.aulro.com/afvb/d3-d4-rrs/153269-flat-battery-advice-please-2.html) had Drivesafe mentioning some very interesting news :The USI-160 is intended for vehicles where electric winch operations are going to be carried out." traxide link (http://www.traxide.com.au/Traxide.html)

Both had my question about an isolator for my winch take a totaly diferent heading so I hope you do not mind me starting a thread on this topic as a standalone one.

Questions ( if you can add if your brand/model of winch it will be helpful to others)
Does your winch allow 12 or 24 volt input.
Would a USI 160 still need a isolator
Does a USI 160 put 12 or 24 volt to the whinch like Denos set up?No see PDF download it is 12.6 volts (http://www.google.com.au/url'sa=t&rct=j&q=traxide%20usi%20160&source=web&cd=1&ved=0CGEQFjAA&url=http%3A%2F%2Fwww.traxide.com.au%2Ffiles%2FUSI1 60_Install.pdf&ei=HC3oT4v0H6mtiAeQv71Z&usg=AFQjCNFyeM3LO-YRMwoux5ag_u6vnyvs8A&cad=rja)
Could Traxide or other dual battery controlers options put 24 volt to the winch and act as an isolator in one unit espicialy if the USI 160 in car control could remotely swtich the isolator?

Design wish list perhaps?

This will be fun I hope:D

Not 12 and 24 it is either or with both availble

"They are separate winches. Most components the same, but you cant change the 12V winch to a 24V winch. But you have an option to purchase wither or."

I was watching a video recently and there was a demo of a guy winching for a recovery and he had a setup that I couldn't work out. One winch, one motor (low mount) but he had an internal switch setup to switch between 12/24v which apparently (and at least visually on the video) altered his line recovery rate. Set to 12v for winching with load but for free line recovery when re-spooling line switched to 24v and ran faster.

I would have thought that this would fairly rapidly lead to early smoke leakage from the system at least or conversion of motor internals to recyclable lumps of metal.

Didn't mobs like Gigglepin pump 24V into their (high mount) 12V motors for faster recovery, knowing that the motor life would be reduced? I don't think the reduced life was appreciable even in winch comps so recreational drivers would probably never notice a reduction in life. This was before they started doing dual motors on their high mounts.
Might be a different matter with the cheaper aftermarket motors around now, the original Warn motors might have been more robust to start with.

EDIT: Just read that with dual or triple motor winches you can only power one winch for slower speeds and two/three for higher speeds.

I'm also interested in how they run 12 and 24v at the same time. Obviously at least dual batteries, but more like a single 12v and dual 24v ?
