Numbers and theories pulled out of a dank orifice don't make it any less conjecture. But if you're really curious, I stopped when you suggested the Model 3 is "...being supplied with 18650 cells fit in a 2170 can.".
and most funny of his "theory" is that's base 3 where margins are razor slim... make more complicated version of big pack to sell in cheapest version instead of using less modules... and theory of 3P and 2P config with 3/2x amount of BMS compared to 100000$ Tesla...
