Widely used Easy to use Compact appearance High precision energy transfer equalization High current 1.2A<br><br>Parameter:Inductive energy transfer active equalization board Balanced version :High precision energy transfer equalization, exclusive equalization IC, high current 1.2A energy transfer battery voltage balancer, significantly balancing battery voltage and improving the overall efficiency of the battery pack. Working voltage range: 2.0V-4.5V, universal for ternary/lithium iron batteries. Equalizing current: Adjacent voltage difference above 0.1V (current around 0.5-0.7A); Adjacent voltage difference above 0.2V (reaching maximum balanced current of 1.2A); The smaller the voltage difference, the smaller the equilibrium current. Wiring definition: B -, total negative electrode of the battery pack (negative electrode of the first battery) B1, positive electrode of the first battery B2, the positive electrode of the second battery, B3, and the positive electrode of the third battery, and so on. Colour:As Shown Material:PC+Plastic<br><br>Package Contents: 1 x Equalizer board module<br><br>Only 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. The measurement allowed error is +/- 1-3cm.
