It’s an array of cells either way, it just increases the build complexity in making it more modular and takes up more space to make it so, which leaves you with less battery.
It’s not necessarily just that. It’s certification to work on them, and equipment costs too. The batteries are heavy, and removing them can be done by a layman but most won’t attempt it. Removing them safely and then working on the individual cell packs inside is costly. The average cost of a car diagnostic for labor is something like $200 an hour. Might be higher now. Add to that the cost of the batteries themselves and draining the cooling systems if they have them. Costs add up quickly.

If the issue producing the high repair costs is large batteries, though, one would get lower repair costs.
