im still new to the site, i dont know where to find the photo album. i want too see it.

 

 

looks good, hope it does what you need it to do??

 

me? lol

 

Definitely do NOT wire your batteries in series, or you are going to seriously damage the car. Wiring in series involves taking off one of the battery cables from your front battery, and running it back to the appropriate terminal on the rear battery (ie if you remove the +, hook it to the + on the rear battery); then connect the two open terminals (+ on the front battery, - on the back battery) with a jumper wire (nothing else connects to the jumper wire). This would give your vehicle +24 VDC potential, and you will cook a lot of electronics in your car.

The way you want to connect additional batteries is in parallel. This involves hooking like terminals together; so connecting the + terminals of both batteries together, and both - terminals together (via a cable, or via the body). This maintains the same voltage (+12VDC), while doubling the available amp/hour rating (assuming two of the same batteries used). This way, the alternator can still charge both batteries.

 

I don't have a good pic of the cable going out back, but it runs from the front battery positive post, thru a 50 amp fuse, to the back, thru another 50 amp fuse, and to the battery, along with everything else. I am NOT running a battery isolator, altho I do have one for it. I had it in, and took it back out. Basically I am running 2 batteries for the whole car.

 

Here are some pics of my last system... currently putting in a new setup.

 

Not trying to be rude- but doesn't 50 amps sound kinda low? I would just think if you starting the car on a cold day that you could even pop it; or that even the stock alternator at full output (split between the two batteries) would come close to popping it.

 

Bumpin96- I'd have to agree with you on that.... I believe the one I have in is a 120 inbetween the batteries. Oh and I know what you mean by wiring them in parrallel instead of series... I do have them wired like what you said, Idk why I wrote in series though! lol my bad
