- Ultra-low Rds(on) MOSFETs provide efficient, low-loss operation and reduced heat during balancing. - 2 oz copper thick PCB supports robust, high-current paths for reliable performance. - Ultra-low standby current: current mode < 0.1 mA and balance voltage accuracy within 5 mV. - Capacitance and wiring enable precise balance action: the capacitor works with the charge-transfer slider, the balance board connects to the battery, and the balancing process starts automatically. - DC current range 0-5.5 A; as the battery balance improves, the balancing current decreases; includes a manual sleep switch and sleep current for low-power standby. Use scenarios - Balancing multi-cell Li-ion/LiPo packs during charging for drones, RC vehicles, and power tools to extend pack life and ensure even cell voltages. - Maintenance and repair of battery packs in hobbyist or professional settings where precise voltage balance is required. - Integration in energy storage or backup systems that demand low idle drain and controlled balancing during operation and idle periods.
