No, because the charger will create multiple distinct voltages for the various connections. For example, in a four-cell series lithium polymer battery pack, at top charge each cell will be somewhere around (very roughly, from memory) 4.125V. To charge all four cells through the balancing connector, the charger will create supplies of 4.125, 8.25, 12.375, and 16.5V, which it will apply to the four nodes (with appropriate modification for proper charge cycle management). Each cell will then see 4.125V across it, with each cell floating 4.125V higher than the cell below.
