The big three up front will be the same. Within reason, if you have to use Higher gauge then do so (Alt to battery, battery to chassis, and chassis to engine block). Seeing you will be running multiple batteries I suggest a dedicated ground instead of chassis as well.


I haven't finished this section yet (as you could see, in the middle of researching, and trying to keep it general and NOOB friendly). This should help explain more until I get my rendition up (as there are a few minor issues with this one below)

Dual battery wiring tutorial (and why)

Also very important is if you would run 10 batteries you need to make sure your alt(s) can handle charging these batteries. Batteries themselves introduce resistance within a circuit as well, so that would be something to keep in mind.
