Feature: 1. Inductive Equalizer: The board is an inductive energy transfer balance board, 1.2A energy transfer lithium battery voltage balancer. 2. For Balancing Voltage: Helps significantly balance the battery voltage and improve the overall efficiency of the battery pack. 3. Low Resistance MOS: Built in improved ultra low internal resistance MOS, the balance current is 0‑1.2A, and the voltage difference with the battery is small. 4. Low Power Consumption: Static power consumption does not exceed 20uA, with balance indicator, the smaller the pressure difference, the smaller the balance current. 5. Easy 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 Module1 x Connection Line Note: This board is based on the principle of adjacent equalization and cannot be used as a maintenance tool. To connect the battery, it must be used with lithium battery protection. The voltage difference generated by charging and discharging triggers the work of the equalization board to achieve energy transfer balance.
