Reliable Battery Balance Module — key features and benefits Precise balance control: Balance current adjustable from 0 to 5.5 A. The more balanced the battery cells, the lower the balancing current required, improving efficiency and reducing unnecessary heat. Low idle consumption: Manual sleep switch plus low quiescent current reduce power draw when the unit is idle. High-performance MOS design: New MOS circuit board with 2 ounces copper thickness for extremely low internal resistance, improving current delivery and thermal stability. Ultra-low current mode and accurate compensation: Current mode less than 0.1 mA for minimal bleed when fine balancing, and compensation voltage accuracy within 5 mV to keep cell voltages tightly matched. Capacitor and transfer charge slider: The capacitor works with the transfer charge slider to manage charge transfer during balancing. Simple operation with balance board and scale: When the balance board is connected to the battery and the scale is started, the module begins operation for hands-off balancing. What this solves Prevents cell imbalance that shortens pack life or causes uneven performance. Minimizes energy waste and heat during balancing thanks to low internal resistance and precise control. Offers controlled, low-power standby and a manual sleep option to conserve battery or charger resources. Key specifications and attributes Balance current range: 0–5.5 A MOS circuit board: new design with 2 ounces copper thickness Internal resistance: extremely low (due to thick copper MOS layout) Current mode (low-current operation): < 0.1 mA Compensation voltage accuracy: within 5 mV Controls: manual sleep switch; transfer charge slider with capacitor interaction Operation trigger: starts when balance board is connected to the battery and the scale is started Compatibility and installation notes Designed to work with standard battery balance boards and battery scale setups where the balance board initiates the balancing process. Physical connections follow the balance board wiring; ensure compatible voltage and connector standards before use. Manual sleep switch allows safe shutdown for storage or transport. Typical use scenarios 1) RC and drone battery maintenance: Connect to your battery balance board while charging or storing LiPo packs to keep cell voltages matched and extend usable cycle life. 2) Workshop testing and QC: Integrate with a battery scale and balance board to perform controlled balancing and voltage compensation during assembly and final testing. 3) Long-term storage and transport: Use the manual sleep switch and low quiescent mode to reduce drain when batteries are stored, then enable balancing when preparing batteries for operation. Practical considerations For best results, monitor temperature and ensure adequate ventilation when using higher balancing currents near 5.5 A. Verify connector compatibility and proper balance board connection before powering the system. The module’s precise compensation (≤5 mV) and low current mode (<0.1 mA) make it suitable where tight voltage matching and minimal bleed are required. This unit provides controlled, efficient cell balancing with durable MOS construction and low-power operation to improve battery longevity and maintain consistent pack performance.
