Hey guys so im still pretty new to vaping but I want bigger clouds my builds are good, believe me they have good resistance nice coils but they just dont hit good the coils seem to heat up kid of slow and my batterys get super hot sometimes, mostly on the .30-.09 ohm builds my battery is a Samsung probably a fake it has 6a 3.7 volt 2500mah also my batterys drain fast and but I have been looking and found a sony battery with 3000mah 3.6volt and 30a is that going to help me hit harder? im pretty sure its my battery. Can you guys tell me whats up?
