dual battery setup

[sporttrac24s]

Hey, does anyone know what is needed for a dual battery setup? I am running 2 kicker l7 15s with an Alphasonic 2400d amp with a 1 farad cap.

Welcome to this forum! You could either use an isolator or a high current relay/solenoid.

Will I need to beef up the alternator?

How many amps is your alternator, and what kind of batteries will be used?

 

[sporttrac24s]

Its a stock alternator maybe 110 amps. I had an optima yellow top but it kept on dying on me. I think I might go with some kenetic batteries.

This is a diagram from # 44 in my list of useful threads:

Thanx, this diagram will be very helpful to me.

You could just go with this prefabbed wiring set up http://store.summitracing.com/partdetail.asp?autofilter=1&part=PRF%2D40102&N=700+400012+310313+115&autoview=sku

You should probably upgrade your stock alternator too. I got a 200 amp alt from Mr. Alternator http://www.mralternator.com/alternators/ford.html

You could use the smaller pulley like AlDive has. It's from Underdog performance. You will have to get a smaller belt.

i've got a dual battery setup in my X, i didnt upgrade the alternator and everything has been charging fine. Im runing a generic die hard and in the rear hatch is a marine gel cell.

I would suggest not using an isolator...rather a high current relay like the PAC-200.

Less voltage drop.

Also get rid of that cap...its doing NOTHING to help anything at all.

Honestly, the only thing you'd really need is some wire, terminals, and a fuse holder. Run the battery in parallel (+ to +, - to -) with your other one, unless you specifically want one isolated so you can start your car. Then, a high power relay/solenoid is the way to go.

Correction he means run them in parallel, (running them in series would give you 24V) But yea all you need to do is run them in parallel and have a fuse on each end of the wire and your good to go.

That is absolutely correct. I'll fix the original post as I shouldn't try to think at that time of night.

LIke infinity says, you don't need an isolator/relay. We install dual batteries in cars and never ahve isntalled them. As long as you install it and use it right, you won't have problems.

but if your gona hook up 2 batteries w/o a relay or isolator make sure they are the same battery and bought at the same time. If not you will reduce the life expecetency of the battery.
