Unlike passive balancing systems, which waste excess energy as heat, this active equalizer intelligently transfers energy from higher-voltage cells to lower-voltage ones. With a high balancing current of 5A, it can quickly correct imbalances, making it ideal for demanding applications where battery packs experience frequent charge and discharge cycles.

This BMS is compatible with both Li-ion and LiFePo4 batteries, making it versatile for a wide range of applications such as electric vehicles, solar energy storage systems, industrial power solutions, UPS backups, and marine power systems. By preventing cell overcharging or deep discharging, the equalizer enhances cycle life, improves efficiency, and provides consistent power delivery.

Key Features:

  • Designed for 21S battery packs.
  • Active balancing with 5A current for faster equalization.
  • High efficiency compared to passive balancers.
  • Extends battery life and ensures safer operation.
  • Suitable for EVs, renewable energy storage, and high-capacity power systems.

For anyone building or maintaining large battery packs, the 21S 5A Active Equalizer BMS is a reliable solution that helps maximize performance and protect your investment. It minimizes risks of imbalance-related issues, reduces maintenance, and ensures stable operation under heavy loads.

In short, this equalizer is not just an accessory — it’s an essential component for modern high-capacity energy storage systems, ensuring long-term durability and dependable power output.
