garton05 Posted April 9, 2011 Author Report Share Posted April 9, 2011 Well ya see in theory, if you have a 270A alternator and back batteries your runs front to rear only have to supply the current that the alt can produce + or - for the voltage drop so lets say 300A depending on length of your runs this could be done with one or two runs of 1/0... IF you connect your alternator to the front battery and have the runs going from the front battery to the back batteries, your runs now have to flow the current that the front battery + alternators can discharge, i dont know about you but batteries are rated in CRANKING amps, ya know like 1000CCA Now you need a hell of alot more runs right? Also mismatching batteries is not optimal. Ever seen a SS CRX burp car, how many runs from the front to rear do they have? With the jeep i had 1 run of 1/0 per 300A alternator, and had a .1-.2 voltage drop full tilt between front and rear. I'm still not catching on all the way. What about a diagram of what your meaning.
