Or engine cylinders. It's possible to make a very large single cylinder engine and in the past that was fairly common, but now typically when you need more power the solution is to increase the number of cylinders working on a common crankshaft.

Yep, true, but that is largely obsolete now, as cars are quickly evolving from 4-cylinder power to 3-phase power :) 
Now that is real power ! :bullshit:

The same principal applies. Rather than one or even a few huge batteries, they use hundreds of small batteries and increase the number when more power or range is needed.

Stray Electron:
  And Tesla is even using dual electric motors now.

      Big isn't always better.

bidrohini:
Very sad. Sounds like there are so many hidden ifs and buts in Tesla's claim.
