Most charge and balance at the same time.
Balancing after charging is not recommended IMO for 2 reasons:
1) Balancing discharges any high cells so if you do it after the charge, your pack will have less capacity (very little though).
2) If you have an imbalanced 4s pack that the charger is dumping 16.8v on, one of the cells might be at 4.3 while the others are at 4.16v. The chargers just knows to CV charge at 4.2v X the number of cells.
