I looked up the source of $10 and as far as I can tell CATL said the raw material costs were $10 and then 'influencers' who were basically Matt Ferrell got it mixed up and said that was the price.
I presume the actual price will be set by what the market will pay, probably starting more like $50 and falling over time.
Firstly you probs need to compare averages, not the lowest, shittiest quality E-rated cells.
Then - why would they sell them at discount? They offer superior charge performance (dramatically higher rates and cold weather performance) when compared to LFP. LFP is a PITA in cold climate. I never get negative temperatures yet still get cold gated even in shoulder seasons!
