Fake AW 18650? Please help.

Wow lots of good info!!! I remember seeing a thread with how to check for real vtc5's I'm going to go see if I can find it!

Can anyone with experience take a look at this and tell me the best battery in the list. I'm leaning towards the vtc5 because I've read that even if it is a fake it is a 2500mah panasonic and they actually work better in regulated mods like mine. I am also interested in the 3100mah IMR Panasonic. I can't seem to find any info on a 3100 IMR only non IMR's...Mis labelled?

Ok so people are freaking me out about these batteries I didnt know this was a big issue. This is what Im using, are these legit? So AW IMR are the best, is there an advantage to using unprotected batteries? Why not just buy the protected? WHy use stacked instead of an 18650?

Oh I use a Vamo and an SVD primarily, both regulated but Im probably buying a mech mod soon, why not just buy protected?

I could be dead wrong about this, but from what I've read and gathered IMR's are the safest chemistry and for that reason they do not need to be protected. I read that for thermal discharge to begin it's around double the temperature, in the 400 degrees I believe (that might be Celsius)

So to me it's like putting airbags on a tank versus a car. Sure it could happen, but probably not.
There are some good battery articles I've read on here so it would be good to read those and double check anything anyone tells you (including me), it's your hands and face that are at risk. It's also easier for someone to tell someone else that jumping off a bridge is safe, but I'd rather see someone do it and survive first.

You never know what is inside of any counterfeit battery. It could range from a great battery like the LG18650HE2 or Samsung-25F or be a re-wrapped harvested battery from an old laptop computer. You just never know, so making a statement that even the fake Sony's are safe is a big misconception.

The "best" battery is the battery with the right specifications for your application. How many amps continuous do you need? How long do you need the battery to last between charges?

If not using sub-ohm coils, the battery with the highest mAh rating is best. If you use sub-ohm builds, higher amps become the priority. For sub-ohm builds, never build a resistance which will pull more current than the amp limit of the battery you use. Use the table below which lists the resistance of the coils you'll make and what batteries you'll require:

• AW 2000 mAh 10 amp limit
• Panasonic NCR18650BE 3100 mAh 4 - 6 amp limit (not high drain; essentually an ICR battery)
• LG18650HE2 2500 mAh 20 amp limit
• Sony VTC4 2100 mAh 30 amp limit
• Sony VTC5 2600 mAh 30 amp limit

1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw <-- Panasonic (6 amp limit)
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw <-- AW (10 amp limit)
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw <-- LG (20 amp limit)
0.2 ohms = 21.0 amp draw <-- Sony VTC4, Sony VTC5 (30 amp limit)
0.1 ohms = 42.0 amp draw <--[this resistance is too low for any 18650 battery on the market]

Protected ICR li-ion batteries are considered to be obsolete for use in mods. Only unprotected IMR batteries should be used in regulated and mechanical mods. The reasons why are in this blog:

Thanks as usual for the info!!!
I picked up the vtc5. I know the amp discharge is overkill for my vamo, but I figured if (and when!!!) I upgrade to a mech mod it will be useful.

Ok so this says IMR I guess its cool? I dunno I still use a bunch of panasonic li Ion batteries, you mean obsolete as in just IMR are better? or Li Ion is more dangerous...I mean I vape at 10 watts at the most I dont do any sub ohm stuff I doubt Id be at risk of blowing a regulated mod up no matter what I stick in it.

Technically the Panasonic NCR batteries are IMR/hybrid batteries, part of the newer "hybrid" family of batteries which use both ICR and IMR chemistry. ICR, IMR, and IMR/hybrid batteries are all in the even larger family of Lithium batteries. Hybrid batteries have been designed to have the better charactistics of both ICR and IMR.

It has been determined by the majority of battery experts that IMR batteries are superior to ICR batteries because they are safer chemistry (less likely to vent flames or explode during battery failure) and are high drain in performance.

Many of today's mods, including regulated as well as non-regulated, require high drain performance from a battery. This translates into a battery capable of high bursts of energy, having a low internal resistance, and having at minimum 6 amps continuous discharge rate.

An ICR battery is of a volatile chemistry (flamable). It is low drain in performance, has a high internal resistance, and has a continuous discharge rate of only 2 - 3 amps.

Deeper Understanding of Mod Batteries

__________

Your reasoning that you are at low risk of blowing up a regulated mod is sound, mainly because it has built-in protection circuitry to prevent that from happening. However, from a performance perspective a high-drain IMR battery is going to allow a regulated mod to perform at its optimum ability more so than an ICR low-drain battery. IMR batteries are superior to ICR batteries in nearly every way.

So to answer your questions:

Yes, IMR batteries are better because they are safer and offer better performance. Yes, ICR batteries are more dangerous because their chemistry is more dangerous and their performance characteristics are inferior to IMR.
