They are using chargers and/or dischargers to find out the characteristics of the cells such as the capacity, the voltage or the resistance and then put those with similar readings together to form a pack. Some look for highest capacity, others may look for lowest resistance or highest voltage.
2 points of doing the above:
1. better cells are put together to improve performance.
2. reduce chances of damaging the cells when they are charged in series (not independently).
