cgrez33 Posted April 30, 2014 Report Share Posted April 30, 2014 (edited) If a DC Power 270xp is the largest alternator you can fit under the hood. D3400 Up front. What would you recommend to run as a battery bank in the trunk for 10k rms?

alaskanzx5 Posted April 30, 2014 Report Share Posted April 30, 2014 Depends on the vehicle but I think a good start would be 5 batts. Biggest you can get to fit in what ever area you have. Do some voltage drop tests then add more if needed. 2 runs 2/0gauge or 4 runs 0 gauge min and in this case it might be more beneficial to do ground runs but if I was you I would do frame grounds and runs.

TeamHT Posted April 30, 2014 Report Share Posted April 30, 2014 If your budget allows four D3100s. If it doesn't, then two and monitor your voltage Quote Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
cgrez33 Posted April 30, 2014 Author Report Share Posted April 30, 2014 Ok so I currently have in my vehicle 1 DC Power 270xp 1 d3400 under the hood 4 d3100 in the trunk. So in a perfect world I could possibly run 10k?

alaskanzx5 Posted May 1, 2014 Report Share Posted May 1, 2014 Possibly, you didn't mention vehicle ( some are known for low charging voltage) or wiring. Also need to make sure your not clipping because it can create more heat which is bad for electrical. if you go for it watch voltage drop and just make sure you top your batteries off ad much as possible.

ChevyBoy95 Posted May 1, 2014 Report Share Posted May 1, 2014 Im at ~8k total.... 270a Alt, 3 D3100's, and 1 S3400, voltage full tilt is about 12.0v flat. I would suggest 4 D3100's in the back, but more so, dual alts or a bigger one like a 370.

TeamHT Posted May 1, 2014 Report Share Posted May 1, 2014 I think the 270 and four D3100s would really be manageable, but like Chevy said more alternator would be nice. What's your budget, that's the best way to find a suitable option. Maybe dual 270s and two D3100s Quote Tell me...does this smell like chloroform to you?

I was curious about this because I really can't fit anymore batteries and want to stay in the trunk. So I was curious to see what I can get with what I got. I really doubt I can fit another 270 under the hood.
