Inductive energy transfer equalization board, high current 1.2A energy transfer battery voltage balancer, significantly balance battery voltage, improve the overall efficiency of the battery pack Balance indication: When the equalization light is on, the equalization work is turned on. The equalization light goes out, the equalization circuit sleeps. The equalization light flashes, indication is lost, or the circuit is faulty.Principle of equilibrium: This module is adjacent to the differential pressure equalization, and the adjacent battery voltage difference reaches 0.1V or more. The internal trigger balance is working until the adjacent battery voltage difference stops within 0.03V. 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.Working voltage is 2.0V-4.5V, ternary iron lithium battery is common, lithium cobalt oxide battery is not applicable.Equilibrium current:Adjacent pressure difference is 0.1V or more (current is about 0.5-0.7A)Adjacent pressure difference is above 0.2V (maximum equalization current is 1.2A)The smaller the differential pressure, the smaller the equalization current.Wiring definition:B-, the negative pole of the battery pack (the negative pole of the first battery)B1, the positive electrode of the first battery, the positive electrode of the second batteryB3....... and so on.Type: 4Scolour:As shownMaterial:metalPackage Contents:1 x Balance BoardOnly 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.
