Dual battery wiring tutorial (and why)

I have a couple of possible issues. The batcaps terminals are like set in, which means I would have to bend the bus bars to be able fit them down in the terminal. You see what I'm saying?

then use short 1/0 pieces. i'm not familiar at all w/ batcap

edit: yes. go with that.

It's just that the **** terminals are inset so I would have to bend them down like an inch and then bend them back up.

I don't think so.

But If I bend the bus bars I think it would work. And it would be a hell of a lot easier.

you could def bend them. but have fun w/ that.

hold up...

inset like this?

just turn them to face each other and bolt that **** up.

edit, that wouldn't work. they would be on opposite sides //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

And it would be easier than having like 4 ring terminals on each battery. What If I did a bus bar, but not on the battery? Like I ran some runs of 1/0 from the 2 batcaps to a bus bar that is fused?

you could do that too, but i'd measure how much drop you have with all the extra wire/bars.

Hmmm ya. I don't know, I'm just going to have to mess with it.

I've had some unlucky trial and error. Not with my system, but just with my truck overall.

Here's a view of the terminals on a batcap:

looking at that, could you not use a bit longer bolt with washers to compensate and just go right over the top of them?

like this:

bolt -> bus bar -> washers (to fill the gap) -> batcap.

Ya I guess I could. I just haven't messed around with it yet. I'm just thinking, it would be best to use copper materials, right?

good stuff.

copper would be best, yes. i've personally never used bus's, but i think i've seen aluminum also. but i'd try and go with copper.
