from the front one?

Not sure if it's necessary but almost everyone does. One fuse right after the front batt and one right before the back one. So 2
i do as its to protect the battery(s) in the back

edit: and if someone can prove this to be wrong please do so would save me some fuse holders in the future :)
i dont fuse it 2 times between the font and back. One fuse between the 2 batts then one after the batt before the amp
Well I have a 300 amp fuse on the line running to the back just to be safe. The only reason I was asking is because I would gain 0.3 volts at idle if I didn't have a fuse on the line. Then for the run running from the rear battery to the 1500 I just used a 200 amp.
