Terminals on studs: Four and no more

One thing to keep in mind- the bolt itself is not meant to be current carrying- it is simply to mechanically affix the terminal to the base. Using the bolt to carry current would mean using the threads to carry current- and that brings all sorts of problems.

I question this statement as well - the studs do not have a base on the battery isolator I purchased for our pickup several years ago.
To mount the cables, the isolator manufacturer supplied two nuts per stud - a base nut, then a binding nut. When these nuts are used, they press against the spiral of the threads which has plenty of surface area to match or exceed the amperage rating of the device. In this case, the isolator was a 130 amps and used 1/4" studs.

Here's a pic of the Sure-power unit - the same as I use:
