What this module does Inductive adjacent-compensation balancing module for lithium battery packs. It detects voltage differences between neighboring cells and transfers energy from higher-voltage cells to lower-voltage cells to restore balance automatically during charging and discharging. Key benefits (why you need it) Improves overall battery-pack efficiency by actively reducing cell voltage imbalance. Lowers maintenance costs by restoring adjacent cell voltage errors to within 0.03 V, reducing the need for manual cell servicing. Automatic operation: compensation is triggered only when needed, so the module works during normal charge/discharge cycles without manual intervention. How it works (clear and specific) Principle: adjacent voltage-difference compensation. The voltage difference generated during charging/discharging triggers the balancing plate and the internal chip to transfer energy between adjacent cells. Trigger thresholds: compensation begins when an adjacent cell voltage difference exceeds 0.1 V and continues until the difference is reduced to within 0.03 V, at which point the module stops compensating. Operates during both charging and discharging whenever neighboring cell voltage differences occur. Technical specifications Type: Inductive energy-transfer balance card (adjacent compensation). Maximum energy transfer current: 1.2 A. Working voltage range: 2.0 V to 4.5 V. Intended use: must be used together with a lithium battery protection board when connected to the battery; not a standalone maintenance tool. Compatibility and limitations Compatible only when used in conjunction with a lithium battery protection board; not a replacement for a protection or maintenance unit. Not a maintenance tool — it performs active balancing during operation but does not replace diagnostic or repair procedures. Practical applications (examples) Multi-cell lithium battery packs for portable power stations and backup power systems where automatic cell balancing improves run time and longevity. Electric mobility batteries (e-bikes, scooters) to reduce cell imbalance that can shorten pack life and lower performance. RC models and drones where consistent cell voltages maximize usable capacity and protect sensitive electronics. Operational advantages Automatic, localized balancing between adjacent cells reduces the time and energy lost to imbalance. High transfer current (1.2 A) provides effective correction without complex external circuitry. Restores adjacent cell voltage error to near-perfect values (within 0.03 V), helping extend pack service life and reducing intervention frequency. Installation reminder Connect the module with the battery through a compatible lithium battery protection board. Do not use this module as a standalone maintenance or protection tool.
