Features: 1.17S, are available for lithium ternary, lithium iron phosphate, and lithium titanate, 2.Hybrid equalization, reducing complexity to simplicity without the need to detect the voltage difference between batteries, directly transferring energy between adjacent capacitors and then high-frequency equivalent parallel connection. The microcontroller main control is combined with low resistance MOS transistors, providing excellent low-power performance and efficient high-precision equalization effect. Long term use of equalization accuracy can reach 0.005V-0.01V, with lower circuit power consumption. 3.The operating power consumption is approximately 1.5-2.5mA, and the battery cell voltage can be automatically turned off when it is lower than 2.5V, or manually turned off through a switch. 4.The maximum equilibrium current is about 6A, and the greater the voltage difference, the greater the current. When the voltage difference is 1V, it is about 6A,; 0.5V approximately 3A; 0.2V is about 1.2A (the above parameters are 4S power lithium battery, combined with 10CM 0.75mm square meter, measured, and the voltage collection measurement point is the onboard Plug). 5.The combination can be expanded, and suitable module combinations can be selected based on the battery series connection method. The modules can be reduced or expanded for use, and can be reduced or cascaded with multiple boards for expansion. Please refer to the diagram for specific connection methods.
