24S 4AMP ACTIVE BALANCER (NEEY)(15sa)

Equalizer Testing Machine 8S-24S With 4A Active Balancer (NEEY)

🔋 Product Description – 24S 4A Active Balancer (NEEY)

The NEEY 24S 4A Active Balancer is a high-efficiency active cell balancing module designed for large lithium-ion and lithium-iron phosphate (LiFePO₄) battery packs with up to 24 cells in series (24S). It actively equalizes cell voltages by transferring energy from higher-voltage cells to lower-voltage ones, improving battery health, usage efficiency, and cycle life compared with passive balancing methods.

🔹 Key Features

• ⚡ Active Balancing Technology: Uses advanced energy transfer for faster and more efficient balancing than passive resistive boards.
• 🔋 High Balancing Current: Up to 4 A current ensures quick voltage equalization across all 24 cells.
• 🔄 Cell Support: Designed for 24S battery packs (~72 V nominal).
• 🧠 Battery Compatibility: Works with LiFePO₄, Li-ion, LiPo, and NMC battery chemistries.
• 🌡️ Wide Temperature Range: Operates from approx. –20 °C to +60 °C for reliable use in varied environments.
• 🔌 Self-Powered: Draws power directly from the connected battery pack — no external supply needed.
• 🛡️ Protection Features: Includes over-current and reverse-connection protection for safer operation.
