Dual Batteries
Has anyone here done it? I'm thinking real seriously about running dual batteries. I already
have the isolator picked and have decided where I will put the second battery but I was
wondering if any of you have pictures of a dual setup. If I do it I will be running the winch,
stereo, and aux lighting from the second battery. I will leave all of the standard equipment
and vehicle related components (ie extra gauges, aftermarket ignition, etc.) on the main
battery.

Haha i was going to do this but i got a beefy alternator and a deep-cycle battery. (Sears diehard platinum..4 year warranty sealed the deal for me), (and a High output alternator built by Mean-Green, @ 2,000 rpm idle i probabley put out in the neighborhood of 120 amps). Basicly with a dual battery setup you can connect the second battery to the main, but you risk draining it to the point of not being able to start your vehicle because it is trying to maintain the other battery as well. With a isolater like xskylinedx said you can just flick a switch to tell the isolator to charge the main battery for your electrical system or charge both batteries at the same-time. Quite an awesome thing if you have the applications of needing two batteries
