Frequently Asked Questions:

Q1: Differences from Similar Products

A1: Resistor-Based Passive Equalization (Advantages: Low cost, compact size, stable; Disadvantages: Low efficiency, high heat generation)

Inductive active equalization (Advantages: Reasonably priced, compact size. Disadvantages: Poor stability, prone to failure, average precision)

Transformer-based active equalization (Advantages: High precision, high stability. Disadvantages: Bulky, high cost)

Capacitive active equalization (Advantages: Reasonably priced, high stability, low heat generation, high precision, high efficiency. Disadvantages: Thicker circuit board)

Q2: Wiring Rules

A2: Start wiring from 0V (common negative terminal) in sequence. Leaving 0V (common negative terminal) floating under any condition can easily cause board burnout. Verify wiring sequence—incorrect sequence will burn the board!

Q3: Consequences of Incorrect Wiring

A3: The result is almost always board burnout. Even “experienced technicians” can make mistakes due to overconfidence, so meticulous operation is paramount.

Q4: Wiring Material Principles

A4: Use 22AWG (0.3mm²) cables as standard. Prioritize sufficient length—shorter is better.

Q5: Module Power Consumption?

A5: Ultra-low power consumption at 1.5mA, ideal for continuous operation without shutdown. The LED remains constantly lit. When cell voltage drops below 2.5V, the module enters sleep protection mode to prevent battery over-discharge. (Sleep mode power consumption as low as 5μA)

Q6: Equalization Current

A6: The equalization module can withstand a maximum current of 2A. Actual current may be lower under conditions of small voltage difference, high battery internal resistance, or high connection wire resistance. The 2A board has an equivalent internal resistance of 480 milliohms. {Total equalization current = Voltage difference / (Battery internal resistance + Connection wire resistance + Equalization board equivalent internal resistance)}.

Q7: Operating Temperature

A7: The circuit operates with high efficiency and low heat generation, typically functioning within 30-45°C.

Q8: Lifespan of the Balancing Board

A8: Products undergo rigorous testing before shipment. Under normal conditions (excluding damage caused by moisture exposure, water immersion, reverse polarity, incorrect sequencing, overvoltage, or static electricity), capacitors have a lifespan of 3-5 years (replace capacitors if bulging is observed). The lifespan of chips, resistors, and transistors generally exceeds human lifespan.
