Wiring the second battery?

[Andrew_as 10+ year member]

I have never wired a second battery before. Right now i have a yellow top under the hood. I am going to be buying a hc2400. I already have 0 gauge to the back. Can someone tell me or give me a link to a detailed place to show me how its done? Thanks

We are working on a whole new series of wiring guides and installation manuals, heres a basic schematic for a dual amp / dual battery install.

You wire them in series to the front battery. Be sure its + to + amd - to -. If im not mistaken this way gives you double amperage, where as if you go + to - and - to + you double your volts which is what you dont want at all. Im gonna run 1 1/0 for + and 1 1/0 for -.

Also fuse accordingly within 12 inches aft your main battery and 12 inches before your 2nd battery. (2 fuses on 1 wire in between the batteries if thats a better visual) For my 1/0 im doing 250 amp. I believe 1/0 has a 300 amp max (not to sure) but I fused mine at 250.

Series would probably ruin your day. Right idea, wrong name.

haha opps had the names backwards. I go by pictures anyways. Nothing like elementary drawings to solve real world issues for me. . .

Ok let make sure i got this down! ) gauge wire from front to back battery with a 250 amp fuse 12 inchs before second and 12 after first battery. Than a power wire from second battery to disturbiton block than from block to the amps?! No need for battery isolator or any thing of that nature?

Yes.

You dont need a battery isolator unless you like to play your system alot with the car off.

can you just do a run from first bat to second then another run from second bat to amp... so no distro?

Yes.

well who dosnt like 2 sit in their driveway/park/parking lot and get blitzed to some tunes, gas cost too much to run the car all the time

And the second battery will get charged too?

Yes, the alternator will just see both batteries as 1 huge one. It isn't very smart //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

 

[Andrew_as 10+ year member]

Its not a good idea to do this? I have a 200 amp altenator.

 

[x2o 10+ year member]

No it's perfectly fine, It's the only way. I meant the alternator is not very smart, it can't tell the difference between 1 battery or 10. Lol, I was just making a joke //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
