Battery relocation - ground question

Some of the lugs on the ground cables are cadmium plated, which means that there are dissimilar metals and the "will" be corrosion. My bracket car has a no oxidizing compound on each and every ground connection. When we wired my car, we put ground connections in multiple places and once done we ohmed them out to make "sure" we were grounded. I for one don't need to not make a call to the line because of something as simple as a ground connection.
