Product summary A compact adjacent-cell voltage compensation module that automatically balances neighboring lithium cells when their voltages diverge. It uses an internal chip and inductive detection to equalize voltages between adjacent batteries. Key benefits Keeps adjacent cell voltages aligned automatically, reducing voltage imbalance during charge/discharge cycles. Prevents continued voltage divergence by activating only when needed: triggers balancing when the adjacent cell voltage difference exceeds 0.10 V and stops when the difference is within 0.03 V. Simple integration into battery systems when used together with a lithium battery protection board; no manual intervention required during normal operation. How it works (clear, specific) Inductive detection monitors the voltage difference between adjacent cells. When the voltage difference between two adjacent cells reaches more than 0.10 V, the internal chip engages the balancing circuit to transfer energy and reduce the difference. Balancing stops automatically once the adjacent cell voltage difference is within 0.03 V. Important attributes Function: adjacent-cell voltage difference compensation via inductive detection and on-board control chip. Performance thresholds: activates at >0.10 V difference; deactivates at ≤0.03 V difference. Compatibility: designed to be connected only as part of a battery system that includes a lithium battery protection board. It must be used with a protection board to connect to batteries. Limitation: this board implements adjacent compensation only and is not a battery maintenance tool or standalone protection device. Practical applications Multi-cell lithium battery packs in portable equipment where adjacent-cell imbalances can develop during repeated charge/discharge cycles. E-bike and power-tool battery assemblies to reduce localized cell voltage drift during use. DIY and small-scale battery assembly lines where passive, automatic adjacent-cell balancing is needed as part of an overall protection and management solution. Installation and usage notes Connect only as part of a system that includes a lithium battery protection board; do not use this module alone as the sole protection or maintenance device. Intended for adjacent compensation; it will not perform full-pack balancing or act as a maintenance charger. Observe the module’s activation thresholds (0.10 V trigger, 0.03 V stop) when evaluating system behavior and balancing performance.
