Product Description

Core parameters

Working voltage: 12.8V (4S lithium battery system)
Balancing current: 5A continuous output
Balancing method: capacitive energy transfer technology
Efficiency: ≥92% (peak working condition)
Protection level: IP65 (dustproof and waterproof)

Technical highlights

Lossless balancing: Energy transfer between cells is achieved through high-frequency capacitor charging and discharging, reducing traditional resistor heating losses.

Adaptive algorithm: Dynamically monitor the cell voltage difference and trigger balancing with 0.1mV accuracy.

Compact design: 86mm×50mm aluminum alloy housing with integrated heat dissipation fins.

Application scenarios
Electric vehicle battery pack maintenance
Solar energy storage system
Industrial UPS power supply
