3S–6S 1.2A Active Equalization Board for LiFePO4 & Ternary Lithium Batteries

Keep your lithium battery pack running at peak efficiency with this high-precision Active Equalization Board. Designed for 3S, 4S, 5S, and 6S configurations, this capacitive energy transfer balancer delivers up to 1.2A balancing current with an impressive 3mV balancing accuracy — ensuring every cell in your pack stays in perfect harmony without wasteful heat dissipation.

Unlike passive balancers that burn off excess energy as heat, this board transfers energy between cells capacitively, making it far more efficient for energy storage systems, solar setups, e-bikes, and DIY battery projects.

Frequently Asked Questions

Q: What battery types are compatible with this active equalizer board?

A: This active equalization board is compatible with both LiFePO4 (lithium iron phosphate) and ternary lithium batteries (NMC/NCA), supporting 3S, 4S, 5S, and 6S cell configurations.

Q: How does capacitive active equalization differ from passive balancing?

A: Passive balancers dissipate excess cell energy as heat, which is wasteful and can raise operating temperatures. This capacitive active equalizer transfers energy directly between cells, improving overall efficiency, extending battery life, and keeping the board cool during operation.

Q: What is the maximum balancing current and accuracy of this board?

A: The board supports a maximum balancing current of 1.2A (actual current may vary based on voltage drop, internal resistance, and line resistance) and achieves a high balancing accuracy of 3mV for precise cell equalization.

Q: What wire connector does this board use?

A: The board uses a PH2.0 connector with a 24AWG, 30CM supporting wire included in the package, making installation straightforward for most DIY battery projects.
