I am looking for some info about my KGO. I was using it this morning ( had been vaping with it for about a hour after charging it for 4 hours ) with the same Vision eGo Clearomizer I have been using the past couple of days. It didn't stop firing when the button was released but the blue light went out so I quickly unscrewed the carto. Soon as I got the clearomizer off the button began blinking and hasn't stopped. It shows to be putting out .98 VDC when checked with volt meter. Everything looks fine and the center connector isn't touching the side.The carto is working fine on my other battery . Any Ideas what could have happened? The battery has been trough about 15 cycles.
UPDATE :It was/is the Vision Clearomizer. It did it to my other battery but the blinking stopped on the second Battery as soon as I unscrewed the carto . I went back to the other Vision Clearomizer ( I bought 2 to try ) and it is working well other than a funny taste due to me using orange in it without cleaning the watermelon out first. I guess something is shorting inside the first carto when moved a certain way or something , IDK. It has no resistance now so whatever happened internally stayed that way. Lesson learned , Fully investigate something like this before risking your back up. It is odd , My original battery is still blinking over 12 hours later and I have no Idea what to do to stop it.
I had a similar experience. The first battery started blinking just as you've described. I made the mistake of trying the bad carto on my backup battery. That one got smoked completely. In the future, I'll trash a carto, rather than ruin another battery. Hard lesson to learn

I ended up just buying new batteries
