Reply to comment by PckMan in ELI5 why do electric vehicles have one big battery that's hard to replace once it's expired, rather than lots of smaller ones that could be swapped out based on need (to trade off range/power/weight)? by ginonofalg
smaller batteries? Do you mean cells?

all of the EVs I know of are batteries made of batteries. The individual modules are multiple cells, those are then stacked together.

Tesla batteries are literally just a lot of Panasonic 18650 batteries (ie, the lithium aa) wired together. They're not modular because it's a mess.
