PIC Balancer - Final Cell Balancing (example 'E1')

This illustrates how the balancer achieves final balance:
The high cell (pink square) is not quite in balance in the first and second measurements
So it starts a discharge cycle in the third whch is terminated immediately when it overshoots
This was enough to bring its voltage down to the same level as the others and the program ends
That cell is showing sugns of drift back up if left a bit longer and the cycle would repeat until it settles
