    Buyer Beware
  

*by M***D on Reviewed in the United States on November 14, 2022*

I purchased a set of three of the Aoicrie 4S 30A 3.7V 18650 Lithium Battery BMS.  I was excited because of the wiring harness for ease of installation.  I have used two of them in LiIon battery pack projects and neither has worked as designed.  The first was DOA and the second one would not power either of my two HAM radios; I'm not going to waste my time to use the remaining unused BMS.  I've used 20 of another inexpensive BMS from Amazon without failure, but these are junk.
