Winch power supply

Steve B · 2009-12-15T18:54:53+00:00

I have a winch I can buy for $200 that is almost brand new. It is a 12v. Vortec 9500 # winch. I can use it for some skidding I need to do onto my trailer, but then, would hang it on an I beam dolly for hoisting. Since it is 12v. what would I use as a power supply that would give me the same as an automotive setup?Steve

They work too.

A bit of advice: A standard automotive battery won't last long for anything more than occasional (emergency) use of a winch. A few discharges will damage a starting battery. Consider investing in a deep cycle battery.

Right. The other thing to consider is the winch motor locked rotor current. Either a battery or a power supply will have to supply this for a fraction of a second. Not all power supplies can do so, even if they can provide 200 percent running current.
