Why are dozens of 18650s the best solution for high watt projects/products? Like, I’m sure the Tesla battery isn’t just a thousand 18650s, so why do so many (diy projects and professional products alike) just scale up by adding more of these relatively tiny lipstick-tube sized cells?

There were indeed Tesla models that actually did that AFAIK. It is also how more or less every li-ion handheld power tool battery is made and I think most e-bike battery packs – those that aren’t stacked pouch cells that is.

Easy to find, easy to use, state of the art energy density for the good quality ones, each of those tiny lipsticks can do 25-30 amps current safely.
