Frequently asked questions:
Q1: Differences between similar products
A1: Passive resistive equalization (advantages: cheap, small size, stable; disadvantages: low efficiency, high heat generation)
Active inductive 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 size, high price)
Active capacitive equalization (advantages: affordable price, high stability, low heat generation, high precision, high efficiency; disadvantages: high circuit thickness)
Q2: Wiring Rules
A2: Starting from a 0V front wiring (total negative pole), a 0V suspension (total negative pole) in any state can easily cause combustion plates, make sure to confirm the line order, incorrect combustion plate order!
Q3: Consequences of connecting the wrong wire
A3: The result is essentially to burn the map, and the "professor" is too confident and easy to capture, so careful operation is the best policy.
Q4: Principle of wire use
A4: The specification for the corresponding wire is 22 AWG (0.3 square meters). The length is sufficient as a guideline; shorter is better.
Q5: What is the power consumption of the module?
A5: The module's power consumption is as low as 1.5 mA, suitable for long-term, continuous operation. The light remains on continuously. When the battery cell voltage drops below 2.5 V, the module enters standby protection mode to prevent excessive battery discharge (standby power consumption is as low as 5 uA).
Q6: Equalize the current
A6: The maximum current that the equalization module can withstand is 2 A, and the current is not so important when the voltage difference is small or the internal resistance of the battery or the resistance of the connecting line is large; The equivalent internal resistance of the 2A board is 480 milliohms, {total equalization current = drop voltage / (internal resistance of the battery + resistance of the connecting line + equivalent internal resistance of the equalization board)}.
Q7: Operating temperature
A7: The circuit efficiency is very high, the heating power is relatively low and the general temperature is about 30 to 45 degrees Celsius.
Q8: The lifespan of the equalization card
A8: The product is shipped after rigorous testing, non-human-caused damage (such as water soaking from humidity, reverse connection out of sequence, overvoltage, static electricity, etc.), capacitor life of 3 to 5 years (replace the capacitor when bulging is detected), chips, resistors and transistors generally last longer than a human life.
