From the electric truck article:

A: I wonder what they have as a battery. Tesla, for example, uses conventional 18650 finger batteries combined into huge cassettes.

Same as the 18650. Why should this tractor use something else?

WB: I should not, but I could. I am hoping for a breakthrough in the field of power supply. Electric vehicles are the engine of progress in this area.

gsg: must have a cassette of Tesla batteries... so that the segment can be extracted and inserted into the Tesla... in general, the standardization of auto batteries is needed

Its: It is even cooler if the whole body can be inserted into a truck, in a specially designed slot. :D

Even more cool, if the three future Model 6 will automatically team up a tractor, from 5 - a personal electric aircraft, and from 12 - an orbital shuttle :)
In order of flight of fantasy and dreams...
