      Comments about Warn Dual Battery Control Kit:

      Warn needs to clarify that this unit is made for ATV's and similar utility vehicles NOT for pickup trucks or SUV;s except for maybe very small Pick-ups. It only accomodates up to a 30amp hour battery with a max system tolerance of around 60amps. You can get or build better systems for a good amount less money that will accommodate larger vehicles, batteries and higher amps.
