Are IMR batteries really necessary with a regulated mod?

[mwjones]

Hey all! Just a quick question. I'll give you a little background info as well, but my main question is whether IMR batteries are really necessary.

First, regarding my current setup. I started out with an 1100mah ego stardust kit. Went to a kanger mini protank 3 after about a week, and bought a 1300mah spinner about a week after that. I got a kayfun mini clone that was a piece of absolute garbage, and am currently in the process of returnign it. I started rebuilding my own coils for the mini protank and everything seems to be going well.

Then one of the connections let go on my spinner. Then I sat on my ego and broke it in half. SO I'm looking to get into a regulated mod. I don't want anything huge like a Vamo with 18650s, and I'm not really into box mods or I would think about an MVP. What I'm looking at is a Coolfire 2. No reason really as far as specs are concerned, as it's quite similar to a Vamo or VTR except that it's vw only, I just like the look of it. I'm not too concerned about the lack of VV, as from what I hear, VV is SO last week and VW is the wave of the future.

So here's my question. Looking at 18350 batteries, i notice all of the IMR batteries are either 700 or 800mah, whereas the ICR 18350s are 1100-1200mah. My 1100mah ego lasts about a day for me (put it on to charge when i go to bed every night or it dies by about 10am the next morning), but I'm worried that the 700mah IMRs are not going to last the day, and I don't want to carry around a bunch of stuff like extra batteries and juice and junk with me all the time.

My current setup with a 2.0 ohm coil and 3.7 watts ego, as far as my calculations, should be drawing about 1.85 amps at about 6.85 watts. I'm figuring that I'll probably stay in the same range with the coolfire 2. Say, just for the sake of argument, that i start vaping at 12.5 watts, the Coolfire's max wattage, it should be running at at about 5 volts, 2.5 amps. Now, assuming that I might switch to a 2.2 ohm coil to try to suck a little extra vape time out of the batteries, it would be runnign at 5.25 volts and 2.4 amps roughly.

This is at MAX wattage, which I probably won't use given the <7 watts setup I'm currently using. Is ti really necessary to use an IMR battery? Would a 1200mah protected ICR really have any significant chance of being dangerous? I don't intend to ever use anything close to the 1.0 ohm bottom limit on the coils.

EDIT: I forgot to mention that I also intend to upgrade to a Taifun GS. I know it's little, but i like the look of the way it builds as opposed to the Kay fun style.

Thanks

If your worried about size and battery life get a mvp2 last a day or two goes up to 12w I believe or higher and you can use it as a pass through and charge your phone with it other than that idk much about 18350 batts just tha I never cared for then much they all kinda suck to be honest oh and I would always avoid anything with fire in the name
Baditude use is the resident wizard with batteries so hopefully he will comment too

If you are going to get a metal tube, I would stick to imr batteries. I just don't trust icr and that dumb blue wrapper. Imo

 

[KenD]

Those ICRs probably have an amp rating that's too low. In any case, batteries can fail in regulated mode as well, and seeing as ICRs failing are far more dangerous than IMRs it's always a good idea to go for the latter (a regulated mod exploding is no different from an unregulated mod exploding). Also, don't mind the mAh rating too much. First; many manufacturers tend to exaggerate the ratings. Second; battery capacity is calculated from 4.2 to about 2.5 volts, you'll use them only from 4.2 to about 3.3, and high discharge batteries have more of their juice in the higher voltage region. Thus you might get more use time out of a nominally lower capacity high discharge battery.

Also to note: in my experience EGOs tended to last a lot longer than similarly rated 18-series batteries. Probably due to higher stress on batteries in vv/vw mods, but could also be due to different rating methods.

IMR vs ICR - same answer regardless every time when the purpose is for vaping - IMR.

Also protected battery in a protected mod genrally causes some wonky problems. (protecting protection apparently does not compute well)

Always use the manufacturers recommended battery, in the user manual it states IMR high drain without protection.

There is no such thing as a high drain ICR.

From Baditude (our resident battery expert).

"High quality IMRs are currently recommended in place of protected ICR Li-Ion for all applications. reference - Rechargeable Batteries

IMR (Li-Mn) are the safest batteries available for vaping. They use safer chemistry, so they don't require a built-in protective circuit like ICRs do. They have higher tolerence to stress, and although they may vent during failure it is less likely to be as dramatic as a ICR. Should protective circuits fail in ICRs they can vent violently in flames and possibly explode. ICR battery explosion"

[Baditude]

Read my above blog, Battery Basics for Mods: IMR or ICR?

ICR batteries are obsolete for mod use for a variety of reasons.

IMR batteries are safer-chemistry, high-drain, and allow regulated mods (using pulse width modulation & boost circuitry) to perform optimally. If you ever plan to use an RBA (Taifun GS), it will require an IMR high drain battery. Why High Drain Batteries?

There's more to picking a battery than just choosing one with a high mAh rating. Bottom line, ICR batteries no longer have a place in vaping.

 

[mwjones]

Fair enough So, i guess then, my choice is between the red/white 800mah 6.4amp efest and the 700mah 105amp purple efest (what i can get locally). Will i see any advantage payign $3 per battery more for the purple batteries?

 

[David Stevens]

What your looking for in a battery
Is to have a higher rating
Than what your mod is going to use/pull from your battery
When you max. Batteries out
They get hot
And charge state depletes faster
So if you run a battery that has more than whats needed
Battery last longer per charge
And life of battery longevity lengthens

If those amp ratings are correct I would diffidently go with the 10amp

 

[Arnie H]

Never had any issues with my Orbtronic (Panasonic) protected batteries in the regulated mods I've tried. Also tried a protected battery in the Hana DNA 30 clone. No issues. If its a quality battery, the most I'd think would happen is you'd trip the PCB in the battery when cranking up the power. I seriously doubt anything will explode. It's redundant, yes, but I am not certain about those who say it is extraordinarily dangerous.I'm no expert though, and this is based on my experiences only. I rarely need more than 2 amps, or 8 or 9 watts, so have never really pushed it to find out. Regulated mods are nice, but I don't change the power much, so really a waste for me. I might get one that plays MP3 files (if they have one), that might actually be useful.

 

[mwjones]

Hmm. So, i just figured out that with a 2.9 ohm coil (max for coolfire 2 is 3ohm, i believe?) with max 12.5 watts, it will draw 6 volts (all max for the mod) and still only draw 2.1 amps. I realize that maybe the numbers are fudged for some maufacturers, but the cheaper batteries theoretically have more capacity. So what I'm basically asking is, will any life expectancy with the 10.5 amp rated batteries be 1.5x the life of the 6.4amp rated ones in actual vape time (to offset the costs of the more expensive batteries)?

Test/Review of Efest IMR18350 700mAh (Purple) 2014

vs

Test/Review of Efest IMR18350 800mAh (Red)

 

[mwjones]

Hmm...so, going by those tests, as far as I can tell the differences in discharge power and discharge time between the two are pretty much negligible, maybe 2 or 3 minutes difference in the .5a range, MAYBE a minute in the 2amp range.

Reviewer rates the reds as "acceptable" and the purples as "good" and impressive high current capability, but do not get if you want high capacity.

So at this point I'm leaning towards the reds?

 

[dice57]

well yes imr's are necessary, or one of the new hybrid chemistry, are also a good choice. If you have to ask, clearly one needs to investigate vape further.

Taifun GS is a great rba, and can easily handle 23 watts. Almost tempted to get the Nemesis 14500 mech, would look sweet on that. But yeah, don't really care what you think your max watt use is going to be. These things tends to change, but whatever, imr's are the safest chemistry batts to vape with, regardless of amps demanded. It's just the smart thing to do. And if your vape changes you don't have to rebuy batts. Just saying

Yep. That's what I'm doing

I'm vaping to quit, and the only reason I want to get a mod is because egos are pretty fragile and I've already had 2 break on me in 2 months. I am going the least cost intensive route possible. I will not be buying another device unless this one breaks or wears out and cannot be fixed for cheaper than a new one, so I know for certain that i will not ever go over the 12.5 watts max

 

[Goldleadr95]

If your never gonna go over12.5 watts I would just get an itaste MVP don't waste time or money on mods and batteries if you really want to get a nice mod and batteries and get into all the fun there then go for it but if your just gonna rebuild protank coils and vape around 12w I would say stick to something like an MVP no sense in buying a semi when you just wanna pull a kayak if that makes sense? I'm just trying to save you some money is all don't mean to sound pushy

 

[mwjones]

The reason I was looking at the Cool Fire II was because I don't really like the look of box mods, otherwise the MVP would be on the top of my list. As it sits, I can get into a CFII with some batteries for about the same price.

Aaahhh I see yeah I wasn't a big fan if the box design till I got mine but hey if it's the same price and you like the way it looks hell go for it man then if you ever wanna upgrade you have batteries you'll just need the new mod if you have a good store near by go check one out and look to see what they have and get the one you like the most like I sad didn't mean to be pushy just making sure you knew about the MVP and it's goodies before deciding
