Re: 12 volt battery cables as a auxiliary engine to frame ground?

Proper tool for the job is always the best approach.
Jumper cables are made to jump start cars with low batteries.
Grounding straps are made to use for grounding.

if you want to cut up the cable to get a section of cable to make a strap via end clips that's your call. Again a local hardware would have large gauge wire to adapt. Frankly, for the few bucks I'd go to the part store for a ground strap and keep the cables in tact. Sell them, if not needed.

Also, investigate why you think it needs additional grounding as there maybe other issues to resolve.
