Features 1、Cell Balancer: Can test voltage difference between adjacent battery strings and transmit high volt to low volt to achieve voltage balance. 2、Smart Testing: The automatic testing and starting will bring more convenience to your work, also has light indicator for better display. 3、Accurate Work: Built in MOS with ultra low internal resistance as well as 0‑1.2A balance current and balance voltage accuracy within 30mv. 4、Practical Use: Allows for application on Li ion NCM and for LiFePO4, the static power consumption is less than 20uA, safe and reliable. 5、Easy to Install: Comes with a light weight and a compact size as well, the battery active equalizer has a cable for simpler connection. Specification Item Type: Battery Active Equalizer Applicable Battery: Li ion NCM, LFP. Single Cell Voltage: 3.0-4.2V Recommended Battery Capacity: Below 30AH Voltage Balance Accuracy: 30mV between adjacent voltages, typical. Equalization Method: It is detected that the voltage difference between adjacent batteries is greater than 0.1V to trigger the equalization, and the voltage difference between adjacent batteries is less than 0.03V to stop working. Balance Current: 0.1V voltage difference and 0.5A balance current, when the voltage difference is above 0.2V, the maximum balance current is 1.2A. Under voltage protection sleep voltage: The adjacent voltage difference is less than 0.03V and enter the sleep state. Quiescent Operating Current: 0.01mA Package List 1 x Battery Active Equalizer 1 x Cable
