Operating voltage 1.8V-4.5V, for ternary lithium, lithium iron phosphateWorking principle, capacitor charge mover, equalization board access to the battery will open the equalization work above, using the original new ultra-low resistance MOS, 2OZ copper thick PCB, equalization current 0-5.5A, the more balanced the battery current is smaller, reserved for hibernation switch wiring position, hibernation power-off mode work current is less than 0.1mA, equalization voltage accuracy within 5mv Static current of about 12 mA, it is recommended that the battery capacity to be 60-300AH battery applicable With undervoltage hibernation protection, voltage 3.0V will automatically stop into hibernation, standby power consumption of 0.1 mA or less.Supply Voltage: 1.8V-4.5VMaterial: PCBcolour: greenPackage Contents:1 x - Battery Equalizer BoardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
