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