No.
The packs aren’t like flash storage where they have spare blocks to use when one block wears out. Essentially switching in something that wasn’t used at all before.
The cells are all connected physically, being charged and drained. They do not connect and disconnect cells when wear occurs.
They have software limitations on how far to charge and discharge (at what voltage and c rating).
Yes, a larger pack will last longer if the charge/discharge cycles aren’t as “deep”. But no, they don’t have spare cells just to cover wear.
You realize you can also use a microcontroller to completely shutoff cells so they don’t get used until one dies yeah? There’s multiple tech in these packs now.
Some pieces of equipment allow you to put two batteries in it, so when one is depleted it automatically switches over to other one. Same kinda concept, just done at the cell level.
Think of a battery pack like a backpack, it’s lots of cells in series, to make larger batteries, you make the backpack larger and hookup more cells. A fancy controller can control which individual cells are active. Or even think multiple backpacks, now linked together.
