Frequently Asked Questions
Q1:Difference between similar products
A1: 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 rules
A2: 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 line
A3: the result is basically a burn board, "teacher" too confident is also easy to capsize, so careful operation as the best policy
Q4: the principle of wire use
A4: 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 current
A6: 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 temperature
A7:The circuit efficiency is very high, the heat generation is relatively low, the general temperature is about 30-45 degrees Celsius
Q8:The life of the equalizer board
A8: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.

The package arrived in Kyiv in 2 weeks at the Ukrposhta branch. The BMS is of high quality, this is not my first purchase, I am satisfied with the purchase and recommend the seller 👍 🤝

I ordered this balancer to replace the first one, which was similar but arrived not working. The product was well-packaged and arrived undamaged. Lucky that the connector on it is similar to many similar models, so I didn’t have to solder anything – just connected it and everything worked :). I use it on a LiFePO4 battery, 4s configuration. The voltage before connection was as follows: 3.39, 3.37, 3.52, 3.49. After a few hours, the voltage on all batteries leveled out and was 3.37 volts. I have no heating at all, the balancer is completely cold, possibly because there was no significant imbalance in the elements. After connecting, the LED lights up. I recommend the product.

After setting the Lifepo4 to 15A for half a day, it balanced all the cells, otherwise they were about to throw away the power bank. It will continue to operate under the supervision of the balancer 🙂

This is my second purchase. The first board works well, so I think these will work too. This time I bought two boards because the price for two was only slightly higher than for one. The seller shipped the product quickly, and delivery was also fast. After connecting, the LED lights up. My balancer is not heating up, possibly because there is not much imbalance.
