5A 4S Active Balancer for Li-ion, LiFePO4, and Lithium Battery Packs with Energy Transfer Equalization (12V, Electric Car, RV, Storage BMS)
Features:
- Type: Active balancer with capacitive energy transfer for 3S/4S Li-ion, LiFePO4, and Lithium Titanate battery packs.
- High Efficiency: Capable of transferring energy across the entire battery group (not limited to adjacent cells).
- Low Resistance: Uses ultra-low internal resistance MOSFETs and a high-quality 2oz copper PCB for optimal performance.
- Equalization Accuracy: Ensures balance voltage precision within 5mV.
- Adaptive Equalization: Current ranges from 0-6A, dynamically adjusting based on battery imbalance; higher imbalance results in stronger equalization current.
- Dormant Mode: Power-off mode with extremely low standby current consumption (<0.1mA), conserving battery when not in use.
Specifications:
- Working Voltage: 1.8V - 4.5V (Supports Ternary Lithium, LiFePO4, and Lithium Titanate batteries)
- Equalization Current: 0-6A (varies based on battery voltage difference)
- Quiescent Current: Approx. 12mA
- Recommended Battery Capacity: 60Ah - 300Ah
- PCB Thickness: 2oz copper
- Balance Voltage Accuracy: Within 5mV
- Dormant Power-off Mode Current: Less than 0.1mA
Working Principle:
The balancer uses a capacitive fit transfer method to move charge between cells. Once connected, it automatically starts equalization, redistributing energy from higher voltage cells to lower ones. This continuous balancing ensures extended battery life, improved efficiency, and optimized performance for high-demand applications like electric vehicles, RVs, and energy storage systems.
Applications:
- Electric Vehicles
- RVs
- Solar Energy Storage Systems
- 12V Battery Packs for Li-ion/LiFePO4 Systems
