If the cells are in parallel they balance themselves anyway. You only balance cells in series with each other. Computer batteries (well at least the ones we design) have the balancing built into the battery and it is done automatically during charge (a voltage detection IC senses the higher voltage cell in the string and bypasses its charge current through a resistor, effectivly allowing the other cells to 'catch up'. The balancing via discharge is the second way of balancing but is a bit crude.
I would love to get one of these packs to test, i might need to do that soon in the name of competitive product research
