Ultra low internal MOS devices form an ultra low dynamic impedance inverter circuit, achieving high power balancing Auto Balancing: Intelligent MCU chip master management, which can achieve automatic and autonomous balancing work. Automatically detect the minimum voltage of the battery, stop working when the battery has low energy, and protecting the battery from power loss. High in Safety: Equipped with overcurrent resistors at each input end of the string, ensuring safety. Also equipped with automatic voltage detection and analysis function, it is convenient to understand the battery balance situation. Specification Item Type: Lithium Battery Pack Active Equalizer Applicable Battery Types: For ternary lithium battery and lithium iron battery. Minimum Balanced Voltage: 15mV Power Supply: Battery self powered, or 5V 2A power supply. Low Voltage Automatic Shutdown: 3V per string. Self Powered and External Power Supply: < 5mA 12V 1-2A, 4th string power supply. Product Model: BAL-524D Applicable Battery String: 4~24 Strings Maximum Balanced Current: 5A Cable Interface: 2.0, 2.54, 3.81 Balancing: Interface Parallel Energy Transfer Battery Balance State Power Consumption After Startup: 80mA, with 10mV voltage difference. How to Use A. Starting 1. When the current drop through the board gets to 70mV or , the active equalizer automatically starts equalization. The actual current is related to the conduction internal of the MOS transistor on the board. 2. Human intervention initiates active equilibrium. B. Balance Principle: High voltage energy is simultaneously transferred to low voltage parallel to achieve battery voltage balance.
