Balancing doesn't even need to be done at the beginning. In fact, if you can wait until the charging process is about halfway done, and then connect the balancer, any imbalance there might be would be more recognizable since the cells are closer to being fully charged. Then, if the imbalance is large enough (based on how long it is flashing the LEDs for) you can slow the charge rate in order to let it finish balancing before the charger finishes.
