Adjacent-compensation balancing board for lithium battery packs Key benefits Prevents large voltage differences between neighboring cells by automatically equalizing adjacent cell voltages. Reduces risk of overcharge/undercharge imbalance in series-connected lithium cells, improving pack reliability and usable life. Simple integration: works passively with a lithium battery protection board, enabling safer, more stable battery operation without manual intervention. What it does (function and performance) Operating principle: inductive adjacent-voltage-difference compensation. The module monitors the voltage difference between adjacent cells and triggers balancing when the difference exceeds 0.1 V. Automatic stop: balancing continues until the adjacent cell voltage difference falls to within 0.03 V, at which point the internal circuit stops balancing. Intended use: designed only for adjacent compensation within a battery pack. It is not a maintenance or charging tool and cannot replace a battery management or servicing device. Compatibility and required components Must be used together with a lithium battery protection board when connected to the battery pack. It does not function as a standalone protection or maintenance device. Suitable for series-connected lithium cell stacks where adjacent-cell balancing is needed. Confirm compatibility with your pack topology and protection-board interface before installation. Practical applications DIY and small-format battery packs: add adjacent compensation to multi-cell series packs to reduce cell-to-cell imbalance during regular charge/discharge cycles. Portable equipment and power tools: stabilize adjacent cell voltages to improve performance consistency and reduce premature cell wear due to imbalance. Energy storage modules: use alongside a proper lithium battery protection board to maintain voltage balance between neighboring cells in modular battery arrays. Important limitations and usage notes This board is not a charger, maintainer, or full BMS. It performs adjacent-cell balancing only and must be paired with an appropriate lithium battery protection board for safe operation. Balancing is triggered strictly by voltage difference thresholds (>0.1 V to start, stops at ≤0.03 V) as handled by the internal chip and circuitry. If integrating this module, ensure your battery pack design and protection board support adjacent-cell balancing and that installation follows all safety guidelines for lithium battery systems.
