The numbers on packs should represent the load that it can handle using the connections and circuit boards that are present on the pack when you buy it.
700A through 12ga wire and a 4mm bullet connector would be over in a hurry!!! lol
You are probably correct or it is just marketing. In any case, it will certainly handle 40amp charging without any issues. Maybe the cells are capable but the surrounding connectors and wires would melt before you can get to that current. The 700A could be continuous for a millisecond.
I also doubt any 2S or 4S RC car could pull that kind do current before the ESC blows as well. A 4ft+ wingspan plane could pull it running a deliberate lower cell count, thus drawing more current than normal.
In a laboratory set up, you would be able to set up the necessary equipment that can pull 700A to validate the rating.
