Lto Li-Ion Lifepo4 Active Battery Equalizer 24V 48V 10A For Solar Energy Storage System

 

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

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:
