[QUOTE="winkychevelle, post: 8811407, member: 611804"] As long as the battery's ground size is equal ampacity accumulative to all the positive runs you can ground to the rear batt. That's saying you have (2) 300amp drawing amps so 2 1/0 runs the grounds should be the same size 2 1/0 runs or a single 3/0 or 4/0 If you have 600amp of amp draw going to the amps you need to have 600amp of negative return capacity Basically add up all the amp fuse ratings so the same wire in means the same wire out. Using the battery as a distribution point isn't a bad thing [/QUOTE]
