HI

Recently I got a eVic-VTC mini with the smok tfv4 mini tank, and currently using the rba. The device reads the ohm as 0.80 and I'm using 55.5W, so my questions are is the current wattage I'm using safe, what range of wattage should I be using, and what are the danger zone I should avoid? I'm definitely a flavor guy and turning up the wattage up does make some difference but a recent vape explosion incident on the news have me worry. Also, I have two batterys I'm using one is IMR 18650 3.7V and the other one is INR 18650 3.7V.

Thanks you

Hello and welcome to the forum @keplin. Glad to have you here!:)

What is the brand name of each of your cells or what is the CDR (continuous discharge rating) of each of them.
I have a purple one call Efest (IMR 18650 3.7v, 3000 mAh) and the other one is a light green samsung. all it has is a stick said 18659 3.7V 2500mAh and how do you find continuous discharge rating?

Both are 20A CDR. Here are the bench tests results on them.
The best way to determine how many amps you will be drawing on a regulated devise (at minimum battery voltage) is to use the max wattage you plan on vaping at and follow this guide to determine what amp CDR your cell/battery needs to be able to support. Calculating Battery Current Draw for a Regulated Mod

If you stay at ~55 watts (and below) either of the above cells will be fine from a safety standpoint. Though the Samsung is a better cell (it's not a rewrap like the Efest is).

If you plan spending a lot of time at +55 watts, get a 30A CDR cell. The Sony VTC4 2100 mAh would work in this instance. Even though it's a 20A cell, testing results show it can be push to 30A safely.

If you are interested in learning more about batteries/battery safety check out the blogs by @Baditude & @Mooch (two of ECF's battery experts).

Here are links to some of Mooch's blogs:
And a couple from Baditude.
Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.
A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.

Very helpful thank you!
