DJ JDub Posted July 8, 2013 Report Share Posted July 8, 2013 When running a second battery should you run two cables from your first battery to your second? (i.e. positive-positive, then another one from negative to negative) or do you just need to run one positive? Link to comment Share on other sites More sharing options...
Pioneerchuck Posted July 8, 2013 Report Share Posted July 8, 2013 You only need 1 run of + and one run of - But you can always add more runs for more current transfer i guess. Link to comment Share on other sites More sharing options...
DJ JDub Posted July 8, 2013 Author Report Share Posted July 8, 2013 Okay thanks, I had a friend tell me I didn't need to do a run of negative and just ground in second battery to the frame rather than running it to the other one. Link to comment Share on other sites More sharing options...
