3S-4S 1.2A High-Current Capacitive Active Balancer for Lithium Battery Packs

The 3S-4S 1.2A High-Current Capacitive Active Balancer is a premium equalization module designed to maximize the performance and longevity of 4-series lithium battery packs. Utilizing advanced capacitive energy transfer technology, this board actively 'shuttles' charge from cells with higher voltage to those with lower voltage, rather than wasting energy as heat. This process enables a high balancing current of up to 5.5A with near-zero heat generation. Compatible with Li-ion, LiFePO4, and LTO chemistries, it maintains a precise balance within 5mV, ensuring optimal pack health even in high-drain applications. The module also includes built-in safety features, automatically entering a low-power sleep mode if any cell voltage drops below 2.5V to prevent over-discharge.

Key Features:

• Efficient Energy Transfer: Uses high-quality capacitors to move energy between cells with minimal loss.
• Powerful 5.5A Output: Rapidly equalizes large capacity packs with high-current shuttling.
• High Balancing Precision: Achieves a consistent cell-to-cell voltage state within a 5mV margin.
• Broad Compatibility: Supports 3.7V Li-ion, 3.2V LiFePO4, and 2.4V LTO battery types.
• Intelligent Protection: Integrated under-voltage sleep mode protects batteries at 2.5V.
• Compact & Low Profile: Optimized for easy integration into existing battery management systems.

Package Includes:

1 x 3S-4S 1.2A High-Current Capacitive Active Balancer for Lithium Battery Packs
