1.5A 3S 4S 5S 6S 7S Li-ion Lifepo4 LTO Lithium Battery Active Equalizer Balancer Board BMS Balance Module(7S 1.5A)

ModulesFeatures:Product specification: 3S 4S 5S 6S 7SEqualizing current: 1.5A maximum (different from differential pressure, internal resistance, line resistance, etc.)Equalization accuracy: 3mVSuitable for batteries: lithium iron phosphate and lithium ternarySupporting wire: 22AWG, about 30CMNote: Except for 8s, other specifications can be reduced by one stringPackage include:1X module circuit body1X connecting wire 22AWG, about 30CMCommon problem:Q1: Difference between similar productsA1: Resistance passive equalization (advantages: , small, stable, disadvantages: low efficiency, high heat)Inductive active equalization (advantages: affordable , small size, disadvantages: poor stability, easy to break, and general accuracy) type active equalization (advantages: high accuracy, high stability, disadvantages: large volume, high )Capacitive active equalization (advantages: reasonable , high stability, small heating, high accuracy, high efficiency, disadvantages: relatively high circuit thickness)Q2: Wiring rulesA2: Starting from 0V (main negative pole) in the clockwise direction, the hanging of 0V (main negative pole) in any state can easily lead to plate burning. Be sure to confirm the wire sequence and wrong order plate burning!Q3: Consequences of wrong wiringA3: The result is basically burning the board. "Teacher Fu" who is too confident will easily capsize, so careful operation is the best policyQ4: Use principle of wire rodA4: The specification of supporting wire is 22AWG (0.3m2), and the length is sufficient. The shorter the better.Q5: Power consumption of the module?A5: The power consumption of the module is as low as 1.5mA, which is suitable for working for a long time without shutting down. The light is always on. When the battery cell voltage is lower than 2.5V, the module enters the sleep protection mode to prevent excessive battery discharge (the power consumption of the sleep mode is as low as 5uA)Q6: Equalizing currentA6: The limit current that the equalization module can withstand is 2A, and the current is not so large when the voltage difference is small or the internal resistance of the battery is large or the resistance of the connecting line is large; The equivalent internal resistance of 2A plate is 480 milliohm, {total equalizing current=differential pressure/(battery internal resistance+connecting line resistance+equivalent internal resistance of equalizing plate)}.Q7: Working temperatureA7: The circuit efficiency is very high, the heat generation is relatively low, and the general temperature is about 30-45 degrees CelsiusQ8: Life of equalizing plateA8: The product is delivered after rigorous testing. It is not damaged by human factors (such as moisture, water, reverse connection, overpressure, static electricity, etc.). The life of the capacitor is 3-5 years (replace the capacitor when the bulge is found). The life of the chip, resistor and transistor is generally longer than that of human beings.==========Quantity : 1Hign-concerned Chemical : NonePackage : TQFPis_customized : YesType : Voltage RegulatorOrigin : Mainland Condition :
