The main argument I have heard is "it sounds too good to be true, it has to be false"... Imo just looking at how much Tesla has raised the prices and then consider the cost advantage of LFP vs NMC it's either they were selling them at crazy loss before or profit has to be higher than 20%.I'm not sure why the margins are so low on Megapack. At $2M a pop, it's hard to believe they cost more than $1.5M to build. The equivalent of 30 Model S batteries can't be more than $1M. I must be missing something.
Anyway the nice thing for Tesla is that they have them in production and can observe costs and see where there is room to improve. And the physics first cost target has to be a lot lower than $1.5M. And one thing Tesla is good at is rapidly cutting costs and they know their long term ambition for the project. Imo people look to much at where Tesla is today, what matters is where they are going. Do they aim a bit beyond where they will end up? Sure but at least they take big strides in the right direction...
