Battery Epiphany...Maybe?

[StateRoad84]

Since I am just starting in the mechanical sub-ohm world (my first mechanical and rda is with USPS somewhere between CA and FL) I thought I would get my thoughts out on batteries, PLEASE correct me if I am wrong. I have been doing much reading on safety, usage, types of batteries, safer chemistry, sub-ohm limitations as it relates to amp draw and the batteries max amp limitations.

My take away on what I have read is that I will not be building coils less then 0.4 ohms, and that may be pushing it. I think it was Pete Busardo said "the challenge is to build big cloud producing coils at higher ohms" (not an exact quote). I think Rip Trippers said "more surface, more flavor" (again, not an exact quote). I also have gathered that a 20amp battery (i.e. Samsung 25r, LG HE2-call a spade a spade) can handle down to a 0.4 ohm build safely, however a better, safer build would be 0.6 - 0.8 ohms.

Ok, my epiphany. If I do happen to build a 0.3, the Sony VTC's are best at 30amp (I currently only have two VTC4's, my other batteries are lower amps and for my Vamo). If I can't get VTC5's (If you've been looking around you already know they are few and far between) should I go for the Samsung 25r? Probably. Now the controversial, the Purple Efest 2500 "35amp" (yes, I put that in quotes) battery at 20amps, would I buy it? I would probably get an LG HE2 if they were available.

My first and foremost goal in doing this is SAFETY. I like my hands and would be very upset to lose either of them and not be able to build coils. That is part of the fun of this "hobby" as I call it (my wife would argue that it is a hobby).

Sounds like you have a good grasp of things.

I have found that while I have the knowledge and equipment to build low resistance setups. I prefer many of my rda's built to .5 to.6.

Plenty of clouds and better flavor. I have found I personally chase flavor more than clouds.

I personally have and use the efest batteries you mentioned,. and they work just fine. As long as you assume them to be a 20A battery. And i prefer anywhere from 0.5-0.7ohms. seems to be the best amount of flavor and vapor, while not killing me or my batteries.

Same sentiments as anumber1 and Chris. I build to 0.6 ohms consistantly. That way, should my SonyVTC 30 amp batteries be charging (I share a couple with my live-in son), I can safely use my AW18650 IMR 10 amp continuous batteries in a pinch. I feel I get an extremely flavorful vape with a good amount of vapor production with this build.

I also have plenty of safety headroom should a short occur. I'm not pushing my batteries at their upper limits, so they'll last a little longer on a charge and should have a longer overall life expectancy.

The Efest Purple's are a re-wrap of the LG DB18650 HE2 batteries anyway. The 35 Amp rating is a peak value and not continuous discharge. There are a limited number of companies making high drain cells and lots of companies rebranding them. It's reviewed and tested here.

I agree, since I started diy-ing my own ejuice flavor chasing is more of what I do. That said, I also love big clouds. Thank you baditude for all the work you've done on your battery postings.

Curious, how long, on average, do the VTC4's last with say a .7 build? (I do vape a lot).

Go with 20r. 25r last longer but the 20r hits harder. Any of the batteries you listed will handle the builds you want and then some perfectly safe. With a .7 ohm build you will get a long vape time. Even a .4 ohm build on any of the batteries you listed, will have no issues.
