3S~21S Li-ion LiFePO4 Battery Active Equalizer 1.5A Balance Protection Board

 
Features:
Up to 1.5A balanced current, efficient balanced and low consumption stable mature and reliable circuit structure to eliminate the risk of similar failures (balanced current varies with the difference in voltage between batteries)
Low resistance high frequency ceramic capacitors, high quality components for high performance and reliability (capacitor appearance and parameters may vary from batch to batch)
Low heat generation, high reliability and high accuracy, suitable for internal battery pack work or external equalisation for battery maintenance, equalisation accuracy up to 3mV
Wiring plug, 24AWG pure copper connection plug (30CM wire length).
The capacitive lithium battery active equalisation module is used to equalise the voltage between lithium battery packs, and the protection board operates independently without affecting each other. Suitable for battery pack PACK, maintenance, and DIY battery pack use.

Frequently Asked Questions
Q1:Difference between similar products
A1:Resistive passive equalization (advantage: cheap, small size, stable, disadvantage: low efficiency, heat generation)
Inductive active equalization (advantages: cheap, small size, disadvantages: poor stability, easy to break, general accuracy)
Transformer type active equalisation (advantages: high precision, high stability, disadvantages: relatively large volume, relatively high price)
Capacitive active equalization (advantages: price is cheap, high stability, small heat, high precision, high efficiency, disadvantages: 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 burned board, "teacher" too confident also easy to capsize, so careful operation for the best policy
Q4:Principles of wire use
A4:The matching wire specification is 22AWG (0.3 square), the shorter the better.
Q5:What is the power consumption of the module?
A5:The power consumption of the module is as low as 1.5mA, suitable for long time working without shutting down, the light is always on, when the battery single voltage is lower than 2.5V, the module enters into hibernation protection mode to prevent excessive battery discharge (hibernation mode power consumption is as low as 5uA)
Q6:Equalisation current
A6:The limit current that the equalization module can withstand is 2A, if the pressure difference is small or the internal resistance of the battery is large or the resistance of the connection line is large, the current is not so large; the equivalent internal resistance of the 2A board is 480 milliohms, {total equalization current = pressure difference/(internal resistance of the battery + resistance of the connection line + equivalent internal resistance of the equalization board)}.
Q7:Operating temperature
A7:The circuit is very efficient and the heat generation is relatively low, the general temperature is about 30-45 degrees Celsius
Q8:Lifespan of the equaliser board
A8:The product is shipped after rigorous testing, not caused by human damage (such as moisture, water, reverse mis-sequence, over-voltage static electricity, etc.), the capacitor life of 3-5 years (found bulging capacitors can be replaced), chips, resistors, transistors are generally longer than the human life.
