Reply to comment by enjoyoutdoors 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

There's some confusion here. Batteries by definition is a collective noun and are comprised of cells. EVs are comprised of many cells controlled by computer processors to manage usage heat and life cycle. Generally you don't want a cell to get about 80% or. Below 30% capacity, nor do you want to wear out a handful of cells charging and recharging constantly becuase they're closer to the inlet/outlet.
