I just got a 510 battery ( joyetech genuine) and put in the USB charger it got so hot that I could barely hold it now it smells like glue it wasn't in there for more than three minutes is it defective or burnt out. Now it blinks when I put a cart on it. Should I try to charge it again? What's the deal I think it melted the plastic on the cap with the led. It's the charger that came with my kit. Idk I'm so aggravated cause it's my manual battery I just ordered. Ahhhh
