4A Smart Active Balancer Balancing Accuracy 1MV 12V 24V 36V 48V 72V Lifepo4 Battery Balance Board Electric Bicycle

 

The active balancing technology employed by the Enerkey 2-24S 4A Active Balancer ensures that each cell within the battery pack is charged to its maximum capacity,

eliminating the risk of overcharging or undercharging individual cells. This not only prolongs the overall lifespan of the battery pack but also enhances its performance by maintaining a consistent and optimal state of charge across all cells.

Wiring Diagram

When used for battery packs with less than 24 string cells in series, the empty pin is suspended.

When used for battery packs with a total voltage of less than 25V, an external DC power supply is required

EK-24S4EB supports cascading use, and at least one battery between every two equalizers is the "common end of energy exchange". The following uses the 32S as an example to describe how to install and connect cables:

Notice:
1.When used in cascade, there is at least one "energy exchange commonend" between every two equalizers. When welding, please note whetherthe connection here is correct.

2.During cascading use, please check whether the wiring is wrongrepeatedly.lf it cannot be used after connection, please contactafter-sales personnel to consult the corresponding cascade diagram.
