Connecting 3 or more batteries

[djjdnap 78]

Came across this site and thought i would post it for you guys.

pretty interesting.

Hmm..good find Its nice because it shows many different variations of wiring multiple batteries. This'll definitely help the n00bs

Edit: maybe you can sticky this?

Very nice find!

Thanks for the post and link.

shouldn't each of those batteries be grounded to separate grounding spots on the cars frame? rather then 1 long run from the front all the way to the back?

[djjdnap 78]

Its better when you run the ground all the way back.

I remember reading something about the ground straps and spot welds not being as good as running str8 wire.

[Shogen 325]

pin for sure.... I think I can manage the last setup..

[shizzzon 461]

I have a question about this..

What if, like me, i have 6 batts and 4 amps?

Each amp will be wired to be able to pull up to 600A of actual current..

So.. i'm assuming it would be a bad idea to run 2,400A worth of potential draw ALL to one post and let the cabling or buss bars split the draw...

I'm assuming resistance would build up at that post, correct?

So.. if that's true, how would be the best way to wire it up in that scenario?

[djjdnap 78]

Larger buss bar.

Bigger wire.

let me find this link

[shizzzon 461]

are you referring to the link on post #1 because if you are, i already read it..

When u say larger everything.. that's assuming the current will find path of least resistance to be perfectly distributed...

Freehand wiring...

That's not proper distribution if that's what u are referring to.

not sure what the draw is though on his system

edit:

and also once you have so many batteries yea the wiring diagrams above become cumbersome.

The article is a good example.

Wow, pretty big difference between that first diagram and the second especially with the only difference being the ground to the last instead of the first.

I think I will do that one with mine, seems easy enough.

Thanks for the link!

[shizzzon 461]

while i'm still comprehending the link you posted, i have a question about the 2nd pic in the first post.

While it shows to connect amp on batt 1 pos post, batt 4 gnd post... where does the batt bank ground from?

Batt 1 i assume?

also, where does alternator connect at on the bank? Would it connect on same posts as amp would in that pic?

Give me a while for me to come back with statements or questions to the new link u posted.

I'd email the person who wrote the article, i can only speculate

However Im assuming that battery 1 the top battery would be the one that the alternator and chassis ground would be connected.

Kind of like the supply is on one end and the load is on the other end.

Then the other examples are basically breaking up the idea of that and like the article says balancing the load over all of the batts.

[shizzzon 461]

ok, i'm gonna try and break this down for car audio use so lets try and tackle this together...

4 amps.. they need to be fused.. alternator, will be fused right before batt bank.. and 6 batteries in the bank.

So, all 4 amps will run to it's own custom block, correct?

Each amp will have it's own fuse, so let's say 1 fuse per amp, 4 fuses.

these 4 fuses will run to a common custom block, correct?

From this custom common block, it must make contact with the battery bank...

So how do we go about it from here?

[dimpthepimp 0]

Looks like all the same series wiring...just differents spots to put main pos and neg. Same output...

[shizzzon 461]

This thread is to get equal distributed output to greatly prolong or get better voltage at the equipment.

[djjdnap 78]

Well the block you speak of could be a buss bar.

Or you could have multiple wires coming off of the batts instead of just one. going to each fuse holder then amp.

[shizzzon 461]

see that's the thing.. using multiple cables from the battery bank to go to each amp will result in non-distributed output.

unless i can get 8 of these batts in there which i highly doubt... i'm just gonna have to wire it like everything else.. tons of cables and tons of grounds everywhere.

[shizzzon 461]

or you know what, i'll contact XS power and talk to them about this wiring diagram and see if they think running ~2,400A to the same post will still work or not.

Wow that looks great and is a shit ton of power.

Oh Shit. Now that's some POWA !

mmmm. florida. lol. jk. jeffery is a nice guy though. his english isnt the greatest, but hes always willing to help out however he can.

i love seeing the actual math and theory behind the real life results of things sometimes. the original link was great. somewhat difficult to apply to a massive set up, but i think i should be able to figure it out with my 6 batts and 1 big amp.

i guess my only thought is, i would have the alt charging on the same pole as the amp is drawing from. its all going to the same place at some point, but it seems logical to me to have whatever current you can get from the alt headed straight to the amp in order to get maximum potential out of that.

[djjdnap 78]

^^ I agree about the alternator str8 to the amp
