1500 Watts? Are you sure? The formula P=IE, or I=P/E = I=1500/12=125Amps.
Thats a whole lot of juice. Do you have water cooled jacketed batteries?


========================================

Why is a 125 amp intermittent load a problem?

Most engine starters draw that much or more.

Right, but they operate only for a reasonably short time. I don't know - I was
just impressed by the fact that 125 amps is a helluva load for deep cycle
batteries, which have endurance.

But admittedly not, at first, for the 4D and 8D batteries Mr. Locke has. Except
that cranking amps are not supposed to be delivered for what certainly must be
several minutes of work. I haven't any figures on it, but would be concerned
about how long a sustained draw could be maintained, repeatedly, on D series
storage batteries before they died.

I think that if I needed a winch with that much power I'd look into hydraulic
ones, or those operated with 120vAC.
