Frequently Asked Questions:
Q1: Differences between similar products
A1: Resistive passive equalization (advantages: cheap, small size, stable, disadvantages: low efficiency, large heating)
Inductive active equalization (advantages: affordable price, small size, disadvantages: poor stability, easy to break, average accuracy)
Transformer type active balancing (advantages: high precision, high stability, disadvantages: relatively large volume, high price)
Capacitive active equalization (advantages: affordable price, high stability, small heating, high precision, high efficiency, disadvantages: high circuit thickness)
Q2: Wiring rules
A2: Starting from 0V (total negative pole) forward wiring, 0V (total negative pole) suspension in any state can easily lead to burning plates, be sure to confirm the line order, wrong order burning plates!
Q3: Consequences of connecting the wrong wire
A3: The result is basically burning the board, and the “teacher” is too confident and easy to capsize, so careful operation is the best policy
Q4: Principle of wire use
A4: The matching wire specification is 22AWG (0.3 square meters) The length is sufficient as a principle, the shorter the better.
Q5: What is the power consumption of the module?
A5: The module power consumption is as low as 1.5mA, suitable for long-term work 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 the battery from over-discharging (sleep mode power consumption is as low as 5uA)
Q6: Equalize the current
A6: 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 or the connection line resistance is large; The equivalent internal resistance of the 2A board is 480 milliohms, {total equalization current = dropout voltage / (battery internal resistance + connecting line resistance + equalization board equivalent internal resistance)}.
Q7: Working temperature
A7: The circuit efficiency is very high, the calorific value is relatively low, and the general temperature is about 30-45 degrees Celsius
Q8: The life of the equalization board
A8: The product is shipped after rigorous testing, non-man-made damage (such as moisture-soaked water, reverse connection out of sequence, overvoltage static electricity, etc.), capacitor life 3-5 years (replace the capacitor when the bulge is found), chips, resistors, transistors are generally longer than human life.
