So I'm fairly new but have a good vape shop near by but I'm not always there lol so this weekend I decided I wanted to try a dripper so I bought a Atty cubed and my vape shop he set me up withduel Claptons on my ipv 4s but I was intending to use it on my 75w sigelei (it is wonderful) so my concern is when I hit the fire button the batter icon jumps around it will go down then up kinda back and forth the Claptons is running .23 ohms and I have bought brand new green imr 18650 2500mah 3.7 does it on it and also on a red lg 18650 so my question it do I need to put this setup on a bigger mod or is the sigelei safe. Thanks
