Tesla's battery Gigafactory continues to expand as the Model 3 nears production.

The completed portion of the Gigafactory is at 1.9 million square feet, but the under-construction areas will be the size to some 4.5 million square feet once complete.

Here’s some new November 2016 drone video captured by Duncan Sinfield.
