I have the Vulcan-e and also have the cut outs. I have noticed something....
Mine only happens once per battery charge.
Meaning I fully charge the battery and once it dips to between 80-70% it cuts out, I power back up, cut out, over and over up to about 10 times. When it finally stays on it will never cut out again for the rest of that charge.
But upon charging again and getting to 80-70% bam! Cut outs.
Just my experience. Is any body else’s similar to this?
