Didn't have time to read a book. Just the last bit.

What....... That has nothing to do with safety. Just ignorant and stupid.
You are saying its dangerous for me to use a 10A battery when I vape @ 6A
So at what current can I use the Sanyo NCR18650GA battery at? 嗯

Batteries having nothing to do with safety, no comment...

It's better to choose your batteries taking into consideration the max specifications of the mod you plan to use, there can be user mistakes or even bugs altering the settings, and rather be safe than sorry.

Does anyone know the Panasonic NCR18650A?

@ Lama, excellent post, recommended to read for everyone.

Indeed, as I learned just now from you.

The NCR18650A is NOT a high discharge battery and is NOT appropriate for the VTC Mini.

Stick to the Samsung 25R, the LG HE2, HE4, or HG2, or the Sony VTC4 or VTC5.

5.9A is the max pulse (1-2 second) discharge. 1.9A is continuous discharge. If you know your stuff and going under the max pulse 5.9A you can. As long you don't go over it. The new VTC mini V1.20 has a Amp meter to keep it at a safe level.

So what single 18650 batteries are capable of working safely in Power mode up to the max VTC Mini power output of 75W?

Look for High discharge batteries.
Ex: Sony VTC4&5, LG HG2, Samsung 25R
Taking capacity in consideration. So it will last you longer.
I think best for newbie is the LG HG2 3000mAh. Sony VTC4 2100mAh/Sammy 25R 2500mAh you lose some capacity. These are the big players in the battery industry. One more Panasonic/Sanyo. I got their 18650 BD and Sanyo's NCR 18650GA 3500mAh. Both 10A Continuous. No need to carry a 2nd. But only for advanced vapors.

P.S Be careful of Sony VTC battery. A lot of clones in the market. Always buy your batteries from a reputable dealer. Good luck.

PP.S There are other lesser known brands which is basically a rewrap. Ex. Sony rewrapping it to their own brand.

Happy vaping

Stick to the Samsung 25R, the LG HE2, HE4, or HG2, or the Sony VTC4 or VTC5.

The Panasonic is defintally unsuitable. Since I have the Sony VTC5, the diff is obvious on the first 3 or 4 puffs.

Everyone with issues, please first follow the recommendation and get a Sony. This is the recommended battery for good reason.

This just as a follow-up.

230°C @ 30W you are only pulling 6A.(Joyetech CL heads) That's under 10A.
Basically I'm just gonna repeat some of the points Llama made.

VTC's amp meter shows current output to the atomizer, which tells us nothing about battery drain. In fact, it gives us nothing useful.
(I suggest Joyetech make it display current being drawn from the battery cell ASAP as it seems to mislead people in a dangerous way.)

Wattage is what you can use to calculate battery drain.
When power setting is 30W, consider this about 90% of what's actually drawn from battery -- devices are not 100% efficient.
When 90% is 30W then 100% is 33.33W. Current drawn from the cell rises as it discharges (voltage decreases), so the cut-off voltage 3.2V is the perfect value to use.

Current = Power / Voltage
Current = 33.33 / 3.2 = 10.41A

Lets say that VTC has in fact an efficiency of 95%. I that case we have 31.6W drawn from the cell and 31.6 / 3.2 = 9.8A.
So 30W of power means that battery current will rise to roughly 10A when it discharges. Oh, and it starts at about 7.5A.

But you should have had. Please do.

Yes, it has an amp meter. One that gives some people false confidence (but it can be fixed!). Be it the wrong or the correct amp meter -- one should not assume that an amp meter keeps one safe.
