Can the capacity of a battery pack be measured individually
How to test individual cells in battery pack without dismantling?
You can''t test individual cells while they are connected in parallel. So long one cell in the set is good, the whole set in parallel will measure 4V. You can use some more special equipment to guess how many cells are good, but in the end you will need to disconnect them to properly test them.
