Re: (ET) Chargers
Since you said the winch is beefy. I would just wire it to run on 36v.
I have a small portable air compressor I bought at K-mart; it is the
"Truck-Air 125" I believe. It is designed for use on a 12 v auto battery. I
think you know the type I'm talking about. I cut off the cigarette lighter
end and attached some clip leads. I run that 12v motor off the 36v pack,
everytime I use it. So far no problems. And let me tell you it really moves
some air on 36v.
I speculate that the winch you have has an even beefier motor and was
designed for at least 4 times the load you will ever put on it with an ET.
Just run it off the entire pack. It'll be alot quicker too.
