Tesla Roadster 2 Battery Weight. The batteries Tesla uses tend to have relatively low power density and higher energy density, so to get a lot of power, you need a lot of batteries (as It's unlikely that the new Roadster will manage anything close to the original Roadster's weight. As an all-electric supercar, Roadster maximizes the potential of aerodynamic engineering—with record-setting performance and efficiency.
