You are only supposed to winch for about 1 min at a time and then allow the winch motor to cool for about 2 min.
This also allows the battery to keep its charge.
Warn says a single 650amp battery and a 90amp alternator is all that is needed, that is right off of their web site.
Obviously if you were a recovery vehicle and your only job was to pull people out all day long you would need a heavier duty system.

 

Ok so I have nothing to put in this myself but i just went from knowing only that winches pull hard to.....all that haha thanks for the insight guys.
