So I’m guessing that you are asking about where to mount?
Many on this site have mounted 2 additional batteries in one of the outside storage compartments near the two OEM house batteries.
You will need to mount near so that you can connect all 4 batteries with proper cabling.
As long as they are mounted correctly and securely, and the cables are properly connected...you are golden.

The other question that must be answered...
- are they 6 volt or 12 volt
- are they connected in series or parallel

If you don’t know the answers to these questions, you should probably pay an expert to assist you.

Finally...it is always best to start with 4 new/like brand batteries when you decide to attack this mod. That way they will all charge and dis-charge equally.
