This Inductive Active Balancer : Will only balance two nearby battery which voltage defference bigger than 0.2V.When the battery error voltage is above 0.1V, the balance work is started until the error is stopped at 30mv.The built-in improved ultra-low internal MOS, the balance current is 0-1.2A, and the battery voltage difference is smaller.The smaller the current, the static consumption does not exceed 20uA.Working voltage 2.2V-4.5V. and high qualityColour:blackMaterial:PCB+metalSize:100 x 45 x 6.5mmPackage Contents:1 x Capacitance equalizer1 x 22awg terminal line(The length of the cable is about 30cm; the color is random, don' accept the specified color)Only the above package content, other products are not included.Note: Light 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.
