I'm installing a dual batt setup in my truck, much like the one Roger has on his site, starting battery(Red Top) runs the starter, winch and OE fuse box, Aux is for emergency jump starts/acc fuse box, stuff like inverter, aux lights, stereo amp, etc. im using a 200A continuous duty solenoid with a 3 position switch like he has, the only thing left is to get the actual battery. from what ive read, using batteries with an dissimilarities will shorten battery life, even when the engine is running and batts. are charging. The obvious choice would be an Optima Yellow or Blue top, but at close to $200, i really dont want to spend that much. anyone have any experience with using differing batteries in their setup or a suggestion as to a reasonably priced GOOD deep cycle battery? please and thank you in advance <img src="/forums/images/graemlins/smile.gif" alt="" />
