Seapahn, like I mentioned, the last I heard, the EW-9500 is not being produced at this time (I used to be). I can call Stutz and find out if you wish.
Yes, the EW-9000 has the 6.6 hp series wound motor.
Going from 12 volts to 24 volts *should* drop the amp load at stall torque from 550 amps (actual measurement, not advertized) to about 275 amps. You should see less of a voltage drop as well, which is one of the real reasons for putting the batteries in series (the other being increased line speed). But even running another battery in parallel will help with the voltage drop, but not the line speed.
FWIW, even with the increased line speed, your wheel speed will outrun the winch even in 4-lo/1st gear. So the increase in line speed isn't that much of a help (when the vehicle gains traction, it will move faster than the winch line, so you will have to stop forward motion to let the winch catch up).

Dual batteries automatically switching to 24V?

Thanks for the info Goodtimes ... I also saw your post on zr2. I'll definitely hit ya up before making any purchase as I'm still far from actually getting a winch. Just trying to plan my electrical configuration for now.

Goodtimes, I am going by the 24V specs they have posted on the web for the 9500. Yours has the 6.6 HP motor, right? The 9500 seems to have the weaker motor but deeper gears (218:1 vs 172.8:1 for the 9000).Last edited by seapahn; 03-06-05, 10:45 PM.

are you sure that you arent thinking of paralelling the batteries for higher amperage, rather than voltage?
Erik, we expect to get a ~25% increase in line speed by putting 24vdc to the 12vdc winch. Very preliminary testing has been done. Nothing in the field yet, to my knowledge.

Originally posted by seapahnYah definitely ... we've been talking about the TMAX 9500 over on the zr2.com site which seems to be a pretty decent winch ... $575 with free shipping so not a bad price at all.
Seapahn, I am currently testing that winch for Stutz Industries (importer). They have not done 24 volt testing. I am scheduled to do that for them this summer. I have a 6 month durability test I need to finish before I start giving it 24 volts. (FWIW, I have ~500 - 600' worth of cummulative pull on the winch, combination of light and heavy pulls, had the winch submerged under hood-deep water, sun, snow, rain, etc., and the winch has not given me any trouble).
There is a new manufacturing facility being built, and once on line, it will be easier for them to control their quality, and get consistant performance from their winches. That said, I have not been able to break the EW9000 I have installed on the jeep (although I have been trying). The price is very good, and the quality is decent. I would like to run it side by side in some tests with a comperable Warn winch, but so far Warn has not agreed to supply me with a winch for testing.
**edit** It is my understanding that they are currently only producing the EW-6500, EW-9000, EW-10000, and EW 12000. The 9500 is not being produced, but I can verify that if you want.Last edited by goodtimes; 03-06-05, 09:33 PM.

Dual batteries automatically switching to 24V?
Anyone know of anyone who has done such a setup and how they did it? I am going to run 2 batteries in the jeep using an isolator/combiner but am entertaining the idea of automatically reconfiguring them into 24V for winching for example.
I can think of several ways to do it with relays and manual switches (with safety being my #1 concern) so I would like to know if you know of anyone who has done a similar setup and how it has worked out.
The way I have the dual battery setup in my blazer is that the backup is charging all the time but doesn't drain until I flip a switch. Ideally, I would want to have a similar setup and just flip a switch and get the 24V circuit established ...
