Feature: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 01.2A, 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 EqualizerMaterial: PCB, copperPurpose: 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 packWorking Voltage: 2.0V-4.5V, universal for ternary lithium iron battery, not applicable for LTO lithium titanate batteryBalance 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 currentWire Length: Approx. 30cm / 11.8in (pure copper 22AWG terminal wire).Package List:1 x Balance Module1 x Connection LineNote: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.
