**Revised ** **Balancing Principle:** This module features differential pressure equalization. When adjacent battery voltages differ by 0.1V or more, the internal balance activates until the difference is within 0.03V. It works during charging/discharging to correct voltage errors, improving battery efficiency and reducing maintenance costs. **Technical Specs:** - Voltage range: 2.0VC4.5V - Compatible with ternary lithium, lithium iron phosphate, and lithium cobalt oxide batteries. **Key Features:** - Inductive active balancer (for adjacent batteries with >0.2V difference). - High-current (1.2A) energy transfer for fast voltage balancing. - LED indicators: - **On:** Balancing active. - **Off:** Circuit idle. - **Flashing:** Fault or signal loss. - Adjustable current: - 0.5C0.7A (0.1V+ difference). - Up to 1.2A (0.2V+ difference). **Wiring Guide:** - **B-:** Battery pack negative (first cells negative). - **B1, B2, B3...:** Positive terminals of each cell. **Notes:** - Minor batch variations may occur (no impact on function). - Harness color is random. - **Type:** 3S | **Material:** PCB | **Package:** 1 equalizer board. - Slight color/measurement variances may exist due to lighting/display differences. *(Excludes trademarks or ambiguous claims.)*
