1. The Intelligent Active Equalizer (EK-24S15EB) is a balance
management system tailored for large capacity series battery packs.
2. Support 2S to 24S battery packs, Voltage collection and
balancing function.
3. The balance current is maximum 15A, and the balance current is
independent of the pressure difference, even if it is reduced to
1mV, the balance current can maintain 15A
4. It supports the cascade mode please check the wiring above. If
you need to use equalizer on your car, please operate according to
the wiring diagram. We have taken the wiring diagram example of 24s
cascading 36s, which theoretically supports infinite
cascading......
5. It can be used in the battery PACK of small sightseeing car,
scooter, shared car, high-power energy storage, base station backup
power supply, solar power station and other products, and can also
be used for battery balanced maintenance, repair and other
occasions.
Our latest addition is the Enerkey 15A Smart Active Balancer
Balancing Accuracy 1MV 12V 24V 36V 48V 72V Lifepo4 Battery Balance
Board for battery REPAIR
Our customers' satisfaction is our priority, and thus, we have
chosen to provide you with a product that is of the highest quality
and performance. The Enerkey 15A Smart Active Balancer is specifically designed to balance the
voltage and charge of each cell in your battery pack, ensuring a
longer lifespan for your battery.

APP Installation and Use
APP custom settings:1-15A, because of constant current and constant
voltage technology, The balanced current is independent of the
battery pressure difference.
The APP has Android and IOS version. Password: "123456"
1). IOS users download the APP : Search "Enerkey" in App Store to
download
2). Android users download the APP:“http://www.enerkey.cn/”
download
3). According to the battery type and battery string number, change
the parameters
4). In the APP, you can view the total voltage, average
voltage,naximum voltage difference of the battery pack,and the
voltage and line resistance information of each battery.There is
also an alarm function to detect the equilibriumtemperature, MOS
temperature,and battery pack temperature in real time.
Wiring Diagram
EK-24S15EB supports 2S-24S. The following figure shows how to
install and connect cables to the 24S battery string:
EK-24S15EB supports cascading use, and at least one battery between
every two equalizers is the "common end of energy exchange". The
following uses the 40S as an example to describe how to install and
connect cables:
