Vehicle ref. 2012 f250 diesel
2 agm xs group 65 under hood (coming)
1 northstar 220 behind seat
Mechman 370 alt.(coming)
Current wiring big 4+ all 1/0
Current amps jp10.4/ jp63/ jp8.4
Conservative ratings 13000 watts.
I have 2 runs of shca 1/0 ran from fuse holder under hood to the agm in rear.
Is the 2 runs enough To the rear battery then all the amps fed off that battery's buss bars? I will most likely add another northstar 220 behind seat after I figure out my space. Should I run 4 runs of 1/0 to rear battery(s)?
