Was watching Gearz last night and saw this. Thoughts?

Good find, they explained most of it. This is pretty simple, I learned it in HS honors physics. LOL

Basically, it's the old school Christmas lights vs. the newer ones.

 

mine hooks up different than both of those

 

Pics?
Are you running a Battery Selector Switch?

 

When I ran two batters in my Honda's I'd use one of these.

One batter in the front, one in the back.

 

I want to have two in the back, but it seems like a pain to rewire the og battery and I don't know where I would putt them.

What exactly is that?

 

It's and isolater. Basically allows you to charge however many batteries you want, then you can shut off the car and only use the extra batteries to power things and not have to worry about draining your main battery.

It's easy to wire, just run some 4g power cable to the back from the battery up front, then connect that wire to the isolater, then to the next battery.. You run one wire from a power source that turns on off with the truck to the isolaters to turn them on/off.

There is instructions on how to wire them up on the site. And you can find them cheaper if you look around, I paid 60$ each for mine.
