Working voltage 1.8V-4.5V, suitable for ternary lithium, lithium iron phosphate, lithium titanate. Working principle, the capacitor fit fers the charge porter, and the balance board is connected to the battery to start the balance work. It adopts the brand new ultra-low internal resistance MOS, 2OZ copper thickness PCB, and the balance current is 0-5.5A. The more balanced the battery, the smaller the current. Reserve the wiring position of the sleep switch, the working current of the sleep power-off mode is less than 0.1mA, and the equalization voltage accuracy is within 5mv! The quiescent current is about 12 mA, and it is recommended that the battery capacity should be 30-300AH for batteries! With under-voltage sleep protection, the voltage will automatically stop entering the sleep state when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1 mA.
