I'm going to add my

before calling it a night.
Mechs, building, batts, chargers, meters, all this should be researched, thoroughly investigated, and re-read and studied before ever assembling a shopping list. Little knowledge in hand can be the last information ever learned.
It's like this, does someone step into the ring with Bruce Lee or Cassius Marcellus Clay, without first learning to fight and defend?? Does one jump on a rocket powered motorcycle and try to set a new land speed 2 wheel record before learning to ride a bicycle. or what makes the wheels go round??
All the information is on the ecf, many, many build threads, sub forums, everything you need to know is here, go forth and learn. Let me ask you this, have you been able to fill a protank and vape it on a ego batt without it flooding or getting dry hits????
Where are you on your vape journey?? What is you current gear being used and what watts do you vape at? What is you nic level??,
VG %?? what are the ohms of your current atomizer that you are using??? How many amps does it draw???
If you can't answer everyone of those quires, well, you shouldn't even attempt to put a battery into you King
pipebombMod, let alone wrap a wire around a drill bit.
Hey, I'm not being an azz, well, maybe a little, my cats say it's time for bed, and am a bit tired

but if I didn't truly care about all who vape, and this community, frankly I wouldn't bother. that said,
Vape long and Prosper.!!!!
