Capacitive energy transfer balance board (high precision 1mv, point-to-point energy transfer balance).
Blue Bluetooth status indicator: always on, the Bluetooth link is successful; flashing, the Bluetooth link is disconnected.
Advanced active balance means that energy transfer does not need to set up the top balance of the battery. The best working condition is to repair the voltage balance in the full voltage range of the battery,
while the backward passive discharge balance needs to set up the top balance to perform the top pair discharge alignment and balance. The working principles of the two balance are different, and the system settings are also different.

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.
