    can be done either way, if you use a seperate battery you use a battery isolator to allow it to be charged by the main alternator - but of course you have a lot of extra weight to slow your car down - I can run PC + screen + 500W of audio for about 5 hours no trouble of the main batt...

    What kind of car do you drive? I almost wasted the alternator in my civic from having a battery isolator. I have a 250 Watt power supply (that's a lot for a carputer) and I run my carputer off one optima yellow top battery just fine.

    Powering the computer is pretty simple, you replace the power supply that uses house power in your computer with one that uses a car's power. Run a wire from the (+) battery terminal to the power supply, ground it, and you're set.

    Check Here. I have one of these in my WJ (Grand Cherokee) and it is working wonderfully. You are able to switch from using just the main battery only with the aux disconnected, use both batteries in parrellell which also allows the charging of the aux bat(with key in on position), and there is an emergency position to allow you to use both bat in parellell with key off. This setup allows me to run the carputer off the aux bat while it is isolated from the cars main electrical system and then I can charge in whenever I want with a flip of a switch.
