Their BMS handles this. Read their reviews a minor complaint is that it takes 24-36hr to fully rebalance all the cells.
If you have just a slight imbalance it's taken care of by the BMS, as it continuously monitor and rebalances cells. That said, if you had used the battery for a while, and you need to change just one cell, you can't put a brand new one, it must be matched.
That's why we would recommend changing all cells. But the good thing is that changing all the cells in the battery will cost you perhaps $50 with our repairable battery. Compare that with $250-$500 with "classical models" where you need to buy a brand new battery
