I've been vaping along happily so I haven't participated much in the forums, but now I have a problem and need some help. 
Here is my setup: Riva battery, madvapes dual coil tank running 1.5 dc cartomizers. BOTH my Riva batteries have apparently given up the ghost. When plugged in, they appear charged (green light) but they aren't. Pushing the button causes the blue light to blink 8 times....even with nothing connected to it.
So, I don't know if it is the charger that is messed up or the batteries themselves. I have read that dual coils can cause premature battery failure. Do you think that it what happened here? The batteries are about 3 months old.
Is there a better battery that I can use with the dual coil tank system? I'm willing to get something else that will work better because I totally love these tanks!
So main questions: 1. Are my batteries toast? 2. What battery should I get to replace them?
