The balance current is not fixed, the greater the voltage
difference, the greater the balance current. if 0.2V voltage
difference , it can 2.4A balance current. Balance current don't
have fixed value .All batteries are balanced synchronously, not
just adjacently balanced.
The balance current can be measured on the balance wires with a
clamp-on DC meter. At present, 17S , 20S, 24S balance board, no
start voltage difference requirement, balance can be achieved when
connected
can't be used as BMS/protection boards . It only have balance
function . Cannot be used for daily debugging.
Suit for battery : Li-ion,Lipo, Lifepo4,Lithium manganese oxide (if
you want to use for LTO , contact us for custom made )
Way of working:
Transformer push-pull rectifier feedback type, energy transfer.
All batteries participate in balance simultaneously
The high voltage is discharging, the low voltage is charging. Start
condition
When using for the first time, the first 4 series voltages are
required to be higher than 12V (LTO need 5 series), and there is no
voltage difference requirement
The starting conditions after sleep are: charge or discharge (the
sleep function can be cancelled)
Can use together with protection board . but its wiring don't have
relationship with protection board
Can use in parallel to make balance function stronger
Can use in cascade for higher series like 32S , 36S , 40S , 48S
60S, 120S ... and so on

Packing List
Use Manual
APP Installation and Use
APP custom settings:1-10A, 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 your battery type and battery string number,
change the parameters in APP
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
The use of battery power or DC adapter power supply, its wiring
method is the same, only the following two differences:
1 Battery power supply support 4S-24S, voltage balancing accuracy
±3mV;
2 DC adapter power supply support 2S-24S, voltage balancing
accuracy ±1mV. The following figure shows how to install and
connect the 24S battery pack:
EK-24S10EB supports cascading use, and at least one battery between
every two equalizers is the "common end of energy exchange". The
following uses the 36S 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.
