No, did you miss the part where a 1948 vette doesnt exist? That's kinda my central point about the 420ah cells.
Do you think everyone knows that? Still a bad analogy because the "style" between years would be much easier to notice than a single battery cell (that many probably never even saw before).
I just did a Google search for 420ah lifepo4 and got "About 38,600 results (0.56 seconds) " So how is the average Joe supposed to know they don't exist?
