Probably worth watching to see the wires are reversed compared to all the other batteries I have with the same connectors. To be fair you can clearly see the yellow warning labels 01:15 on the batteries but because these batteries were purchased without the manual the labels refer to there is no way of knowing what that warning is all about. That means that I did manage to destroy one of my small USB powered chargers as I tried it first. If I had used my Turnigy charger first I would have been OK as that has a polarity check and that is what warned me of the problem.
===============================
Tim Adams left this comment that covers it: 
Yup, the "Nine Eagles" in the item's title is the key.  For whatever reason, Nine Eagles and also Heli-Max helicopters and quadcopters (just re-branded stuff) are reversed polarity on anything that uses that connector.  As you can imagine, it makes it very easy to let the magic smoke out. :-/
The charge protection circuit is built into the charger specifically meant for those batteries, which can also be dangerous if the wrong charger is used and can let the magic fire out!
