I know what you are saying.I have been sub'ing strictly on my efest batts too,yes I have a .... ton of the reds myself.I have also been stocking up on the 18650 2500Mah 35A purple efest,and the 18490 purple efest too,i seldom go down to 18350 size strictly because battery life just is not there yet.I sub ohm my 35A efest mainly at .5 and I have a few juices I go down to .25.I also have a few Sony VTC5's and AW's but efest are my battery of choice too.
Have you tried out the 18350 purple efest 10.5A batt yet??? I am wondering why they up'd the amp's on the 350's with just 700Mah to vape with?? I also have just acquired a few purple efest 26650's for my Hades,Tree of Life,and El'Gigante MOD's.
