Working voltage: 1.8V-4.5V     Suitable for ternary lithium, lithium iron phosphate, lithium titanate.     Working principle, the capacitor fit transfers the charge mover, the equalization board is connected to the battery, and the equalization is started. The new ultra-low internal resistance MOS, 2OZ copper thickness PCB     Equilibrium current 0-5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv      The quiescent current is about 12 mA. It is recommended that the battery capacity is 60-300AH.          With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA.     Colour:As shown     Material:PCB     Size: 75 x 60mm          Package Contents:     1 x Balance protection board          Only the above package content, other products are not included.     Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
