Hi guys, I'm switching from cigs to vape, and examined a lot of mods to jump to after I started with a smok ego cloud AIO, and pulled the trigger on getting the smok GX350, mostly for battery life. The initial batteries that were available from my merchant (Vape Royalty) were the efest purple 18650 flat top 3000 mAh 35 amp IMR batts. The charger I bought was also an efest being the LUC V4...They were sold out of the batts I wanted, but I'm asking for advice on the ideal ones to get for this rig from a repped place like IMR or Illumn. Also, any danger risk from those efest batts in this rig? Settings to avoid? I was thinking of using it around 100 watts mostly, Thanks!
