Usually bms allow for some sort balanced charging, which means they try to avoid the explosion of one series group while the others are barely charged. Do do that, the board needs to be connected to each cells groups, as shown on this simple pic of 3 cells in series. On a sidenote: it's usually no a good idea to use different cells in the same pack. Each one has its one internal resistance, so usually the one with the lowest resistance wear off quicker.
