I just don't see a reason to run a separate wire back to the battery for charging along with your start circuit all the way back to the solenoid from your neutral switch. Certainly a 1/0 cable will charge back better than a 4 ga would. It's not wrong, just more complicated than I care for it to be.



If we are trying to prevent the dreaded "hot start" issue. I have had luck using a simple bosch style 30/40 amp relay to take the start load off of the ignition/neutral switch to ensure full voltage to the solenoid on the starter.
It's not complicated really, and the charge wire doesn't need to be huge because as you said the alternator should be powering everything from a distribution point up front. Keeping the battery charged between starts shouldn't be a huge deal. I put the battery in the trunk as part of adding the remote solenoid and relay to fix the hot start problem you mentioned. Wasn't a huge deal, and I learned a lot about how relays work and got better at soldering, so it was worth it for me.
