I bought two "5000 mAh" NiMH and they were 1500 mAh. Three lipos from hobbyking led to three fires burning three ESCs and two motors from rippling. I know a lot of people have had good luck with them but I won't touch any non-american non-name brand batteries anymore and they are never allowed in anything I own. I can't afford to buy cheap, paying triple or more for thunderpower turned out to be cheaper in the long run for me.

My story isn't the norm and is the exception, but these exceptions occur more often with the cheap crap because of weak or non-existant quality control.
