Capacitive energy transfer equalization board (high 5mv, whole group equalization, not adjacent equalization) Capacitive energy transfer equalization board (upgrade version) Working voltage 1.8V-4.5V, suitable for ternary lithium, lithium iron phosphate, lithium titanate. Working principle, the capacitor fit transfers the charge porter, and the balance board is connected to the battery to the balance work. It adopts the 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 switch, the working current of the -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 the battery capacity should be 30-300AH for batteries! With under-voltage protection, the voltage will automatically stop entering the state when the voltage is lower than 3.0V, and the standby consumption is less than 0.1 mA.
