Ultra-low power operation with precise balancing - Power mode < 0.1 mA and balancing voltage accuracy within 5 mV. Easy setup and operation - The capacitor works with the transfer charge slider; the balance board is connected to the battery and the unit starts the balancing process. Flexible balancing current - Balancing current range 0 to 5.5 A. The current decreases as the battery becomes more balanced. Includes a manual sleep switch for reduced standby power. High-performance hardware - New MOS board with 2 oz copper thickness and very low internal resistance for improved efficiency and thermals. Use scenarios - Balancing multi-cell Li-ion packs in RC models during charging to improve performance and pack life. - Regular cell balancing in home energy storage or backup battery systems with minimal idle drain. - Laboratory or prototyping work requiring precise, low-noise balancing and reliable operation.
