I would look farther into using Lithium manganese Dioxide (Li-Mn02) Chemistry batteries for vaping.

I don't know enough to say either way.. but I would research before buying. It might depend on what application you will be using them for, regulated or un-regulated.

I have a number of concerns and starting with k702's suggestion above; Li-MN02 is not the chemistry of secondary batteries, which are rechargeable cells. It is a chemistry used for non-rechargeable batteries.

While Madvapes maybe a respected vendor in the US, their claims that a) this cell is the safest battery available, the high amp-limit on these batteries means you can b) build sub-ohm coils without fear of the batteries venting and c) which means hours of use before a noticeable difference in voltage compels a battery change, are totally abhorrent in my eyes.

I have been vaping 4.5 years and I have never heard of PVTSO nor can I find any information about such a company.

The offer of having a maximum charging current of 3A is misleading and to be ignored if you wish to get anything like the expected lifespan from the cell. Anything over 1A shortens the lifespan of a Li-ion cell.

Rechargeable? As said, not if they are the chemistry so claimed.

My opinion is to give them a miss and stay with the proven and accepted batteries oft nominated within this forum.

Well that is what i was thinking. This kind of reminds me of the Vamped battery.

It's my guess that these are re-branded Sony VTC3 1600mah 30 amp (continuous) batteries.

EH re-brands the same cell to be sold under their own label. EH/Sony IMR18650 1600mAh, 30Amp, 3.7V Rechargeable LiMn battery - flat top | SmokTek.com

Doesn't look like a VTC3 to me. The +ve end is different from a Sony:

 

[Baditude]

Looks the same to me. Am I missing something?

 

[pnyc]

Sony VTC has three vent holes. This PVTSO has four and circular in shape vent holes.

 

[seth2769]

also sony has flat negative pole ...these have rised one ...probably second quality china batch.

 

[roosterado]

Maxell makes a Li-MN02 i secondary bateery but it is a 3.3 volt small round flat battery and this is from the spec sheet

This battery contains lithium, organic solvents, and other combustible materials. For this reason, improper handling of the battery could lead to
distortion, leakage*, overheating, explosion, or fire, causing bodily injury or equipment trouble. Please observe the following instructions to
prevent accidents. (* Leakage is defined as the unintentional escape of a liquid from a battery.)

I think it's important to note that Mad Vapes is offerring these batteries in a huge range of sizes so it's unlikey to be any one type of cell that's been rebranded. For myself, I'm looking for improvements in 18350, 14600, 14650 and 18500 sizes.

The 18650 size has plenty of options and this battery is probably ignorable in that size - not so for other sizes. Hopefully manufacturers notice there's an interest in these smaller sizes before scam artist's do.

I don't see much interest from manufacturers in developing other sizes even to 'what's known and proven'. That leaves me in a desperate spot enough to try them and I'd appreciate more reasoned opinion than "I don't know but it's not necessary" BS. For some of these sizes it's the only new thing that's been attempted ever.

Another well known 'not-to-be-mentioned' site is prmoting these batteries in the odd sizes as lasting much longer from personal experience. I'd like to make a decision on a little bit more evidence than that - but that doesn't appear to be in the works.

I just purchased 2 of these batteries (http://www.madvapes.com/pv-imr-18650-1600mah-battery-button-top.html) to check em out. I don't know anything about the safety of the chemistry or the reality of the stats. I do not know if they are rewrapped anything else. I do know that 3A charge looks kind of high to me I do know that the 1600 mah seems kind of low and that they look suspiciously like these batteries http://www.mxjo.net/mxjo-imr-18650f-1600mah-30a-37v-flat-top-high-drain-battery-p-226.html . I am not sure what that means or if it means anything to be honest. (Things that make you go Hmmmmmm.........)

At a quick glance the specs look like the Sony VTC3.

Nobody will know until someone can properly test them however

 

[Kytrix]

The PV branded batteries are in fact new, and Madvapes was definitely the first to pick them up. It looks like the LiMnO2 was a misprint, because those batteries aren't described with that chemistry. They're LiMn batteries. As for testing, those results are now posted to their blog page, and they were compared against several popular batteries. Looks like they performed the same or better. It is a new brand, but the results look like they're of very good quality.

I have a few of these batteries, and while I can't test them with the proper equipment because I don't have it, my experience with them has been great. I think we should keep in mind that Madvapes has been in the game a long time, and is a very reputable vendor. I doubt they would put those specs up and offer those batteries if they were of substandard quality, especially given the liability of using them in the applications a vape shop intends them to be used for.

I picked up three of these in preparation for a mech mod. Initially I couldnt charge them as they both showed with green LEDs in my Xtar and Ultrafire chargers.They tested at 4.0v so I just decided to wait and use them. Well Ive finally used the charges and have tried charging again. Both still give green lights on the chargers but are testing at 3.6v or lower. Going to have a friend try a third charger but Im not pleased with the purchase thus far.

That's strange. AFAIK, chargers use voltage alone to decide to charge or not. Let us know how the next charger handles them.

Just picked them up locally from Madvapes. I haven't had time to test them yet. Putting them beside my VTC 4's, they are the exact same height and width as the VTC 4's. However, the crimp at the positive lead is slightly lower and slightly wider than the VTC4's, and there are four prongs lifting the positive lead instead of the VTC4's three. The batteries have 25A listed on the battery. I asked the salesman about the amperage, and he said they had a 20A continuous, 25A pulse rating, but that is verbal from the salesman. A quick "by hand" judgement is that they're the same weight as the VTC4's as well.

I have not tested these, and unfortunately, I cannot test them side by side with the Sony's. These are going to be matched pairs going into a Sigeli 100w box mod arriving today. My Sony's will remain single units going in my mech mods. The Nitecore I4 has no problem recognizing and charging them.

 

[a wandering soul]

got a pair that just arrived today... ill let ya'll know how i like them. won't be able to play w/ them until i get off work.

 

[a wandering soul]

so far so good... although I havent really done anything crazy in testing them... but they did fire .33 ohms for me vaping steady for an hour lastnight and the only heat discharged was from the rda. ill keep an eye on them, but i dont think madvapes is going to risk their good name to make a few bucks on shady batts. they are a real by the book place..

 

[a wandering soul]

these batts definitely seem to be legit.
