4S 2A Inductive Active Balancing is a technology that uses the characteristics of inductance to achieve charge and voltage balance among each cell in a lithium battery pack. It uses circuits to balance the charge and voltage between cells to achieve the best performance.
Features:
1.Fast Response Speed
The inductor 4S 2A active balancing board quickly adjusts each cell’s voltage to stay within a safe range. Its rapid response effectively minimizes voltage differences between cells.
2.Good Balancing Effect
By transferring excess energy from high-voltage cells to low-voltage ones, this board achieves a consistent state acoss the battery pack. This enhances overall performance and stability.
3.Low Energy Loss
Unlike passive balancing, which wastes energy through resistor discharge, this board uses inductive energy transfer. It moves power from high-energy cells to low-energy ones, reducing waste and improving efficiency.
Application
The 16S 2A active equalizer is designed for large-capacity lithium battery packs, providing precise voltage regulation and equalization control. It handles 2A current, managing large fluctuations and ensuring stable output, making it ideal for high-current applications like electric vehicles and home energy storage
