[QUOTE="UnknowingDIYer, post: 8843262, member: 688967"] What about fuses between batteries? If I have about a 10 run between my front battery and my rear battery, what size fuse should I run? I don’t really know how to think about the current from one battery to the next? Is it all just the current of the 300 amp alternator since it’s all a parallel circuit? Since the 10ft run is longer than the short alternator to main battery run, is it still safe to use welder wire 2/0 for that long of a run? Or should I double up and split the current? [/QUOTE]
