Why you need a Battery Balancing System
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. This yields up to 30% more power and will extend the life of the battery pack.
Benefits:
Quick and easy installation
Keeps your batteries voltage difference within 10mV!
May increase the lifespan of your battery pack by 2-3 times by preventing the batteries from being overcharged or over discharged
