Sounds a bit more complex than needed.. Try this.
I won't argue with "identical battery"
To connect additional battery.
1: Remove NEGATIVE (Chassis ground) cable from existing battery
2: Connect positive on new battery to existing positive
3: Connect negative on new to existing, leave nut loose on new battery
4: Connect Negative (Chassis ground) to new battery and tighten.
No need to disable or unhook anything other than the negative (Chassis ground) as this "Disconnects" everything else.
Re: Master battery disconnnect.. If you have one turn it off before starting, and back on when done.
