Enerkey 20A Smart Balancer 4S 8S 12S 16S 20S 24S 40A 60A with CAN and Bluetooth Active balancer for Electric Vehicle
Smart Active Balancer Equalizer 24s 12-72volt 20A max - NMC/ LFP - For Lithium Battery Packs
This equalizer is suitable for 2~24 series NCM/ LFP/ LTO battery packs with voltage acquisition and equalization functions. The equalizer works with a continuous 20A equalization current to achieve energy transfer, and the equalization current does not depend on the voltage difference of the series-connected cells in the battery pack. The voltage acquisition range is 1.5V~4.5V, and the precision is 1mV.
20A High-Current Active Balancing: Supercapacitor-based energy transfer, efficiency exceeding 90%, 5 times faster balancing speed
24-Series Full-String Monitoring: Millivolt-level voltage detection, real-time warning of abnormal batteries
Intelligent Dynamic Management: Automatic switching between charging/discharging modes, optimizing battery pack consistency
Military-Grade Protection: IP65 waterproof and dustproof, -20℃~60℃ wide temperature range operation, zero safety hazards
Why Choose Us?
50%+ Extended Lifespan: Reduced battery degradation through balancing management, 30%-50% increase in cycle life
Enhanced Safety: Over-voltage/over-current/short-circuit/temperature quadruple protection, eliminating thermal runaway risks
Improved Energy Efficiency: Active balancing reduces energy waste, increasing system efficiency by 15%-20%
Intelligent Operation and Maintenance: Supports data export and remote diagnostics, reducing maintenance costs by 40%
Application Scenarios
Electric Vehicles: Solves the problem of reduced range caused by poor battery pack consistency
Energy Storage Systems: Improves charging and discharging efficiency and extends the lifespan of energy storage equipment
Electric Bicycles: Intelligent balancing of dual battery packs, preventing overcharging/over-discharging of individual cells

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:
