Product information

Product Overview The Heltec Energy 2~24S 4A/7A Intelligent Battery Equalization Instrument is a smart balancing device suitable for 2-24 series lithium batteries (NCM, LFP, LTO, etc.). It can automatically recognize the number of battery strings and utilizes a constant resistance discharge method for balancing, ensuring voltage consistency and enhancing battery lifespan and performance. Product Features Compatible with Multiple Battery Types : Supports lithium batteries with a nominal voltage of 2V~4.5V. Automatic Recognition of Battery Strings : Smart detection of the number of battery pack strings, eliminating manual configuration. Efficient Balancing : 4A model : Max balancing current: 4A for NCM batteries, 3A for LFP batteries. 7A model : Adjustable balancing current 1-7A (max 7A) for NCM batteries; max 3A for LFP batteries. Real-Time Monitoring and Alerts : Supports alarms for reverse connection, over-voltage (4.5V), and low voltage (2V). The device automatically stops once balancing is complete. Comprehensive Voltage Display : Voltage of each cell Total voltage Average voltage Maximum/minimum voltage Maximum voltage difference Balanced voltage Number of battery pack strings Safe and Reliable : Supports a single-cell battery input interface voltage range of -100V~+100V, with an external power supply of 12V 5A to ensure stable operation. Feture Power supply: DC12V 4A/7A Single channel voltage measurement range: 1-5V Single channel voltage display accuracy: 0.001V Single channel voltage acquisition accuracy :±(0.05%+0.003v) Single channel voltage operating range: 2.0-4.5V Adjustable balance current: 1A-7A(The smaller the voltage, the larger the impedance, the smaller the balance current) Applicable battery type: ternary lithium, lithium iron phosphate and other battery voltage between 2.0v-4.5v Operating temperature: 0°C-50°C Working humidity: 20%-80%RH Working environment: no corrosion, explosive and damage insulation gas and conductive dust Package
