Features 1.Inductive Transfer: The board is an inductive energy transfer balance board, 1.2A high current energy transfer battery voltage balancer. 2.For Balancing Voltage: Can help to significantly balance the battery voltage and improve the overall efficiency of the battery pack. 3.Low Internal Resistance: Built in improved ultra low internal resistance MOS, balance current is 0‑1.2A, the smaller the voltage difference, the smaller the balance current. 4.Low Power Consumption: Static power consumption does not exceed 20uA, with balance indicator, universal for ternary iron lithium battery. 5.Simple Operation: When the battery error voltage is higher than 0.1V, the balancing work starts until the error stops at 30mv. Specification Item Type: Active Equalizer Material: PCB, copper Purpose: Inductive energy transfer balance board, high current 1.2A energy transfer battery voltage balancer, significantly balance the battery voltage, improve the overall efficiency of the battery pack Working Voltage: 2.0V-4.5V, universal for ternary lithium iron battery, not applicable for LTO lithium titanate battery Balance Current: The adjacent voltage difference is above 0.1V (current is about 0.5-0.7A); The adjacent voltage difference is above 0.2V (reaching an equilibrium current of 1.2A); The smaller the voltage difference, the smaller the equalizing current Wire Length: Approx. 30cm / 11.8in (pure copper 22AWG terminal wire) Package List 1 x Balance Module 1 x Connection Line
