Okay guys, here's the deal. Many (most) cheap Chinese batteries are made like any other product. Out of a lot of 1000, ~100 are really good, 100 are really bad, and the rest are average. In the US and many other countries, most manufacturers will toss out the bad specimens and sell the top 100 for a premium. This preserves their reputation, whihc in Western business culture has been important for success. Throwing something away is just not a part of current Chinese business culture. The cheap Chinese sellers will put the bad cells in with the rest and sell them all as the same product, relying on low pricing to generate repeat business.
If you are in luck you get either the average or the very good specimens. If not - you get the bad ones. This is the real explanation (barring user error) why some follks have good luck with Turnigy packs, and others have very bad experiences. Virtually no quaity control compared to what we have been used to in decades past. This same reality applies with cheap motors, radios, etc.
I am not meaning to insult our Chinese cousins, but facts are facts. Chinese manufacturers can make outstanding products - but if we always expect to pay the low price, we get what we pay for.
