★ Real-time, active, energy transfer equalization, after the
balance, the inter-cell pressure difference ≤ 3mV
★ Support 2S to 24S battery packs.
★ Single cell voltage collection range: 1.5V ~4. 5V, accuracy: ±
1mV.
★ Support all pool types such as : Li-ion, Lipo, Lifepo4, LTO,
super capacitors and other batteries.
★ The balance current is set independently in the range of 1A-10A,
independent of the cell voltage difference.
★ Support balanced cascading to apply to more than 24S of battery
packs, in theory, can be cascaded indefinitely; for exampel , can
28S , 32S , 36S , 40S ...
★ Support Bluetooth communication, equipped with mobile APP,
real-time view of battery status.
★ Equilibrium line resistance detection, abnormal contact failure
is found in advance.
★ Power supply range: 40V~ 100V.
★ Low voltage shutdown function to prevent battery damage.
★ Super self-protection function, any equalization of the
equalization line will not burn the equalizer.
- The equalizing current on each equalizing line can be measured by a
DC clamp meter.
- We have a nominal 1-10A equalizing current. As long as the voltage
difference is reached, this equalizing current can be measured.
- When the voltage difference is 1V, more than 10A of balanced
current will be generated, not more than 10A.

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.
