The low center of mass is definitely an advantage but sportscars are pretty low to the ground anyway. It makes a much bigger difference in SUV size vehicles where a Tesla handles way better than its fossil competitors.

The heavy battery is a disadvantage for handling because heavier things have more inertia. The physics are pretty complicated and I'm not an expert either but if pressed I would point to aerodynamic downforce as completely independent of weight.
