magillaru Posted October 21, 2014 Report Share Posted October 21, 2014 This is going to be my first "big" battery bank. Going to have 3 runs of neg and pos from front to back. http://i1318.photobucket.com/albums/t658/magillaru/E3F980D3-E9F4-43A1-B854-53BED08F6BB9_zpsgyto4hru.jpg Questions: 1. Should I fuse between each battery? 2. Should I ground the last battery in the group (before the amp) to the ground/chassis or will I be okay since I have the 3 runs from the front? Any other input/suggestions welcome! Thanks! Singer Alternators Team Asshole #anothershittysingerbuild Link to comment Share on other sites More sharing options...
KenSchoen Posted October 21, 2014 Report Share Posted October 21, 2014 IMHO no fuses between rear batteries. As for the other question someone that knows more than me can answer. I've always just grounded the front battery and rear battery/batteries to the chassis and only run a positive wire....but I'm sure someone will tell me I'm probably wrong haha.

OrionStang Posted October 21, 2014 Report Share Posted October 21, 2014 The way your diagram is, you don't need to ground the rear bank to the chassis. BUT it wouldn't hurt. Not sure what wire you're using, but 2+ and 2- should be plenty. Id save on the third run of each. SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
MrSkippyJ Posted October 21, 2014 Report Share Posted October 21, 2014 Fusing between the batteries really depends on how close the batteries are to each other. If they are right next to each other, resulting in a wire that is only a few inches long connecting them it would just overly complicate wiring and present more problems than it solves to try and put fuses between each one. If your batteries are on opposite sides of the vehicle then I would absolutely fuse between them. If you are running 3 dedicated grounds to the back that is all you need. With that much amp you probably won't benefit from a chassis ground anyway.

magillaru Posted October 21, 2014 Author Report Share Posted October 21, 2014 Going to be running 2/0 welding wire from weldingsupply.com. The batteries will be right next to each with the amp VERY close by. THANKS! Singer Alternators Team Asshole #anothershittysingerbuild Link to comment Share on other sites More sharing options...

I've always just grounded the front battery and rear battery/batteries to the chassis and only run a positive wire....but I'm sure someone will tell me I'm probably wrong haha. That's what I did when I was only running one battery in the back but from what I understand, it's better to run the multiple runs from the front vs grounding to the chassis with this kind of power. There's a video somewhere on here with D'Amore engineering shedding some light on this topic....

So what I took from your post is that chassis grounding has it's limits and the more power you have it starts becoming necessary to run physical wire's rather than grounding to the chassis?

zoeboi954 Posted October 21, 2014 Report Share Posted October 21, 2014 great set up, my question is in the drawing is that set of fuse necessary since you have a set near the front battery, just asking cause i never seen that before ........ and yes ground to chassis it wouldn't hurt 4 Fi Q 12s In A Prius on 4 Crescendo BC2000D?!

magillaru Posted October 21, 2014 Author Report Share Posted October 21, 2014 Based on that video where they tested this theory, yes. I'll see if I can find a link. My overall experience with this is very limited compared to the other members on here but that's my understanding of it.

If it's not needed, hopefully someone can confirm this.....would save me some money and time on fuse blocks and lugs!
