This is the top of the line Technology ... all hybrids and electric car will have to use this to compete
You must be terribly informed: Fisker Karma powered by AONE's battery has only 1/4 of electric driving range of a Telsa Model S.
Yes, more batteries = more range.Tesla just added more batteries which cost money. If they wanted to, Fisker could put more batteries in, but that is not their goal. They rely on the backup gas engine for extended range which will be used on a limited basis for most drivers.
