Hey, I'm pretty new to vaping, only like 4 months into it..I have a Sigelei 150 and I love it!! I just went to fire it up and on the display the word 'short!' came up..ugh!! Anyways I noticed the batteries were only at 18%, I've run it this low b4 & never had this come up on the display..I changed the batteries & it seems fine..I'm just wondering has anyone else had thus come up on their display?.. I'm hoping it's just 1 of the batteries is no good and I'm not putting those back in..
