The individual cells in a battery pack are rarely an exact duplicate of all the cells in the battery pack. In actual practice, when a pack of batteries reaches a specified charge cutoff voltage then the charger will shut off. If one cell in a pack reaches that voltage before other cells reach a full charge it will cause the charger to shut off - prematurely denying the balance of the pack a full charge.
Conversely when the weakest cell in a pack reaches its discharge cutoff voltage it will show as the discharge point and shut down the pack prematurely - thereby denying the user the balance of energy the other cells have stored. These battery equalizers prevent this from happening and this yields up to 30% more power and will extend the life of the battery pack.
