Yes I did search but i think this would make a terrific stickie.
I'm trying to figure out how to add an external battery for my Car Pc set-up. I'm going to get a Optima Yellow Top
From what I've searched this is the best for Car Pc's
However I'm not quite sure how the wiring will go to make it work.
Anyone know a site where a layout might be with pictures possible?
Thanks in advance,

Dont use isolator. They arent not worth the money. You will loose about a 1or so volt in the back battery. You might as well just take a (+) from the front battery and fuse it closet to the battery, then run it all the way to the back and fuse it again right by the back battery. I have this setup for years now no problem.
kicker, different setups for different people. I'm going duals w/isolater due to the fact that I have kneebiters. I went out to the burb this morning and low and behold someone had left the rear map lights on all night. I just don't want to forget about the PC overnight/days if not driven and come out to a dead battery.
One would think if you planned on leaving the puter in hibernate or sleep mode for any length of time, a second battery with isolator is a must.
You turn off the car, go inside and sleep. The puter is in sleep mode drawing a few watts. Then 3 days later you try to start your car for work, and the battery is dead. Now while my math of 3 days and a dead battery from sleep mode may be off, it makes a point.
If you had a second battery that is hooked to an isolator that is hooked to your cars battery, the isolator would only let the puter drain from the 2nd battery. ITs worth the time and money in the long run to be able to always have your carputer ready to go and not need to be started up.

Okay - so can someone show me how to connect the main battery to the isolater to the 2nd battery...there's got to be a tutorial website for this but i cannot locate it.
Thanks so far guys - I really appreciate all the post so far.
Keep it up.
Vizion, if you look at the isolator the posts are marked. I'm sure it comes with directions, Stank? Or if you understand prints:
Basically, alternator to isolator, isolator to batteries via 2 seperate + cables.
its fairly easy, from the altinator you have a charging lead(+) from there it goes to the main post on the isolator, then you have 2 posts from the isolator, one for batt.1 and the other for batt.2 now from here depending on your batts and altinator you should run a 1/0 welding cable, some use the performance wire but its all the same your just paying more.Hook the batts. up and your all set.
EDIT: yup the posts are marked
CAREFUL STANK!!!! You may get accused of nOOb bashing! God I love that "other" thread......Originally Posted by n8scstm
