may03LT Posted June 12, 2008 Report Share Posted June 12, 2008 I am starting my rebuild soon, I need some advice because Ive never built anything that needed this much power. I have a high output alt already. Amps are rated 5,800 watts rms. I did some research and found Ill need roughly 2000A of batt to back it up. Replacing the stock batt and adding 2 to the back will put me at roughly 2000A. -do these numbers sound right? -can I use bus bars on a regular 12v system? -if I did go teh bus bar route, do I need to run B+ from the alt to the bus bar? -would the p's and g's need to be rated for 2000A or is the load somehow split across the batts? I got a couple more ?s just cant think of them all right now THX! Link to comment Share on other sites More sharing options...

You might not want to run them for a long time but you could probably run that off a single Yellowtop! - Bus bars are just lumps of metal. Yes you can use them - You don't need a wire directly from the alt to the bus bar. As long as all the batteries are connected to it and the alt is connected to the main battery's + then you're fine. - P's and G's? Come again 10.x volts fo' life!

Yes, you will want to use enough 1/0 to be rated for your amperage, but really you would need around 400-450 amps worth of Alternator to support that without voltage drop. If you don't plan on running multiple alternators, you could do a single upgraded Alternator and one battery in the back to suplement. Bus bars prolly wouldn't be necessary, cause you would only have one suplemental battery in the back. 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...

ChevyBoy Posted June 12, 2008 Report Share Posted June 12, 2008 what type of batteries? cheap shits wont do any good with that type of power. kinetik or powermaster is the case here. atleast 2 2400s or 3100s Link to comment Share on other sites More sharing options...

I'm sure 2 D2400's, or probably even a single D3100 would get the job done. If you use the XSpower batteries, you wouldn't necesarily need to use bus bars, you would have 2 + and 2 - threaded holes, and you can easily stack 3 crimped ring terminals per hole. This would give you more than enough conection points for your amp, 2 grounds and alternator conection. 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
