Product Overview
The 24S 20A Lithium Battery Smart Active Balancer is a high-performance energy management device specifically designed for 24-series lithium battery packs. It utilizes advanced active balancing technology, achieving voltage balance between battery cells through supercapacitor-based energy transfer, significantly improving the overall performance and lifespan of the battery pack. This product is suitable for large-capacity lithium battery applications such as electric vehicles, energy storage systems, and electric bicycles.
Core Functions
Smart Active Balancing: Uses supercapacitors as energy storage elements for energy transfer, achieving an efficiency of over 90%, far exceeding traditional passive balancing methods.
20A High-Current Balancing Capability: Supports fast balancing, significantly shortening balancing time.
24-Series Battery Pack Management: Precisely monitors the voltage of each battery cell, with a balancing accuracy of ±1mV.
Dynamic Balancing Mode: Real-time adjustment of charging current for each battery cell during charging.
Static Balancing Mode: Periodically maintains the balanced state of the battery pack during discharge.
Product Features
High-Precision Monitoring: Millivolt-level voltage detection accuracy to promptly identify abnormal batteries.
Intelligent Control: Microcontroller automatically adjusts the balancing strategy, supporting remote monitoring.
Wide Operating Temperature Range: Stable operation in environments from -20℃ to 60℃.
Strong Compatibility: Supports various lithium battery types, including lithium iron phosphate, ternary lithium, and lithium titanate.
Communication Method: Connects to an APP via Bluetooth or to PC software via CAN.

24S Wiring Diagram
EK-24S20EB supports 2S-24S. The following figure shows how to install and connect cables to the 24S battery string:
17S Wiring Diagram
When less than 24 battery strings are connected in series, empty pins are suspended. The following uses 17S as an example.
3S Wiring Diagram
If the battery string has a total voltage lower than 24V, you need to connect 24V to 120V DC power supplies.
The following uses 3S as an example:
40S Cascade Wiring Diagram
EK-24S20EB 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:
