Buyer Beware
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.

Good current not a BMS
Supplies good current and charges quickly. Would not call it a BMS. Has so protection for battery under voltage or otherwise.

Don't bother.
Total junk. Of the 3 I got none provided the correct voltage at the power out terminals even though all other terminals had correct voltage (b- b1 b2 b3 b+ all read as expected on volt meter) these are junk. I've wired dozens of these in my life It's not a lack of knowledge it's a junk product.

The green layer delaminates, low quality construction
Two have had the green top layer of the pcb delaminate. One of them had the foil also working it’s way of.

Product Stopped Working
I got zero out of 3 to work. It seems like it would work. The balance cable spots reads the correct voltage, but the p- and p+ ports only shows 14 volts. When a load was added, the voltage dropped to 1 volt. Thought it was just that one, but the same thing is happening to all 3. Epic. Fail.
