Frequently Asked QuestionsQ1:Difference between similar productsA1: resistive passive equalization (advantages: cheap, small size, stable, disadvantages: low efficiency, heat generation)Inductive active equalization (advantages: cheap, small size, disadvantages: poor stability, easy to bad, general accuracy)Transformer type active equalization (advantages: high precision, high stability, disadvantages: the volume is relatively large, the price is relatively high)Capacitive active equalization (advantages: affordable, high stability, small heat, high precision, high efficiency, disadvantages: the circuit thickness is relatively high)Q2: Wiring rulesA2: from 0V (total negative) to start wiring in the direction, any state of 0V (total negative) overhang can easily lead to burn board, be sure to confirm the line sequence, the wrong sequence burn board!Q3: the consequences of connecting the wrong lineA3: the result is basically a burn board, "teacher" too confident also easy to capsize, so careful operation for the best policyQ4: the principle of wire useA4: supporting wire specifications for 22AWG (0.3 square) length is sufficient for the principle, the shorter the better.Q5:What is the power consumption of the module?A5:Module power consumption as low as 1.5mA, suitable for long working hours without shutdown, the light is always on, when the battery monomer voltage is lower than 2.5V, the module enters hibernation protection mode to prevent excessive battery discharge (hibernation mode power consumption as low as 5uA)Q6:Equalization currentA6: equalization module can withstand the limit of current for 2A, the pressure difference is small or battery resistance or connection line resistance, the current is not so large; 2A board equivalent internal resistance of 480 milliohms, total equalization current = pressure difference / (battery resistance + connection line resistance + equalization board equivalent resistance) .Q7:Operating temperatureA7:The circuit efficiency is very high, the heat generation is relatively low, the general temperature is about 30-45 degrees CelsiusQ8:The life of the equalizer boardA8:The product is shipped after rigorous testing, non-human caused damage (such as moisture, water, reverse misorder, overpressure static electricity, etc.), capacitor life 3-5 years (found bulging capacitors can be replaced), chips, resistors, transistors are generally longer than the human life.
