- Undervoltage sleep protection: the voltage automatically stops the sleep state when below 3.0V, and standby power consumption is less than 0.1 mA. This helps conserve power and prevents unwanted wakeups. - Wide compatibility and practical chemistry support: working voltage 1.8V–4.5V, suitable for ternary lithium, lithium iron phosphate (LiFePO4), and lithium titanate (LTO) packs. - Balancing mechanism and construction: capacitor fitting transmits the load carrier, and the balancing board connects to the battery to start balancing. It uses a brand new MOS with ultra-low internal resistance, 2 oz copper thick PCB, and an equalising current of 0–5.5 A. The balanced battery is the smaller one. - Precision control and wiring flexibility: reserve wiring position sleep switch; sleep-off current is less than 0.1 mA; balance voltage accuracy within 5 mV. - Power draw and pack sizing: quiescent current is about 12 mA; recommended battery capacity for use with this device is 30–300 Ah. - Use scenarios: - In solar or backup power systems, balance 30–300 Ah Li-ion/LiFePO4/LTO packs to maintain health and prevent undervoltage. - In modular battery assemblies for telecom equipment or portable power stations, achieve precise balancing (within 5 mV) with low standby draw. - In industrial or consumer applications using LiFePO4 or LiTiO2 chemistries, ensure balanced cells during operation and idle periods.
