  Fast Cell Balancing Using External MOSFET (Rev. A)
  PDF, 153 Kb, Revisión: A, Archivo publicado: enero 26, 2009
  The need for cell balancing comes from the fact that cell-to-cell differences in self-discharge, capacity, and impedance can lead to different charge states among the cells. However, the charger terminates the charge based on the summed voltage only, which may leave some cells undercharged and others overcharged. To remedy this imbalance and to achieve the goal of having all cells reaching 100% st
