1Adjacent pressure difference is 01V or more (current is about 05-07A);2Adjacent pressure difference is above 02V (maximum equalization current is 15A);3The smaller the differential pressure, the smaller the equalization current.4This module is adjacent to the differential pressure equalization, and the adjacent battery voltage difference reaches 01V or more. The internal trigger balance is working until the adjacent battery voltage difference stops within 003V. There is an adjacent differential pressure when charging and discharging on the battery pack. Trigger equalization, the battery pack voltage error will be pulled back to the Perfect value, reducing battery maintenance costs.5Working voltage is 20V-45V, ternary iron lithium battery is common, lithium cobalt oxide battery is not applicable. Note:There will be some heat in the first use, no need to deliberately dissipate heat, just use it normallyMaterial:metalcolour: bluePackage Contents:1 * Active Balance 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 picture a little different from the real thing.
