NEEY ACTIVE BALANCER 3S 2A

The 3S 2A Capacitive Active Equalizer Balancer is a high-efficiency energy transfer module designed to maintain voltage balance across 3-series lithium battery packs. It uses active energy transfer (capacitor-based balancing) to move charge from higher-voltage cells to lower-voltage cells, improving battery performance and lifespan.

Key Features

• Active Energy Transfer Technology

Transfers energy between cells instead of dissipating it as heat, ensuring higher efficiency than passive balancing.

• 2A Balancing Current

Fast equalization of cell voltage differences for improved pack consistency and performance.

• Wide Compatibility

Supports multiple battery chemistries:

• LiFePO4 (LFP)

• Lithium-ion (NMC / LCO)

• Lithium Titanate (LTO)

• Automatic Voltage Balancing

Starts balancing when voltage difference is detected and stops automatically once cells are equalized.

• Low Heat Generation

Capacitive transfer reduces energy loss, keeping the module cooler during operation.

• Plug & Play Design

Simple wiring for 3S battery packs, easy integration with existing systems.

How It Works

• Detects voltage difference between cells
• Transfers energy from higher voltage cell → lower voltage cell
• Maintains uniform voltage across all 3 cells
• Improves battery efficiency and prevents imbalance-related damage ([amiciKart][1])

Applications

• EV battery packs (E-rickshaw, E-bike)
• Solar energy storage systems
• DIY lithium battery packs
• UPS / backup systems
