Enerkey 20A Smart Balancer 4S 8S 12S 16S 20S 24S 40A 60A with CAN and Bluetooth Active balancer for Electric Vehicle

Product Description

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
Industrial Equipment: High-reliability battery management, suitable for harsh environments
