2S - 24S Smart Active Balancer 15A Lithium Ion Battery Balancer For E Bike

Li-Ion Battery Energy Equalization 2S-24S 15A Smart Active Balancer With APP For E-Bike

Product Description

The equalization process of this active equalizer consists of the following three steps, which are cycled sequentially until the maximum differential pressure is within the set range:

1. Detecting the largest and smallest monomers;
2. Maximum monomer charging to the super-capacitor of the equalizer, charging current is the set current, maximum 15A;
3. The super-capacitor of the equalizer discharge to the smallest monomer, discharging current is the set current, maximum 15A;
4. Repeat steps 1 to 3 until the differential pressure is within the set range.

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.
