A BATTERY MOOCH POST: QSO 25A 2600mAh 18650…overrated, QSO says it’s LiPo, DO NOT BUY
Bottom Line: This overrated QSO appears identical to, and performs identically to, the Samsung 25R which a 20A-rated 2500mAh cell.
But one of the documents I requested from QSO, the Material Safety Data Sheet (MSDS), says that this cell uses the same “chemistry” as LiPo’s. That does not mean they are dangerous! If they do use this chemistry though it would mean that if they are misused or mishandled they can go into thermal runaway, and possibly burst, at a lower temperature and that their reactions during runaway are more violent than the other Li-Ion chemistries we can use.
I was very surprised to see QSO list the same chemistry as used by LiPo’s in their MSDS since that chemistry, lithium-cobalt oxide (LCO), is rarely used anymore in round cells. I am told by those who know a lot more about the battery industry than I do that the price of cobalt is just too high to justify its use for low cost round cells like the ones we use. Well, they’re low cost when manufactured. The markups in price before they get to us are huge.
The wraps for these cells say “LI-MN” which I am pretty sure QSO wants us to think is lithium-manganese. This is consistent with the chemistry for some non-LiPo cells we use but is in direct conflict with QSO’s claim that these are LiPo’s in their MSDS. There is no manganese in a LiPo cell.
So what’s the big deal about having an accurate MSDS? They exist to inform employees and first-responders of the risks involved if they need to handle a spill or fire involving a product. If the MSDS is wrong that would make responding properly harder to do.
An incorrect MSDS would also mean that any vendor importing those cells into their country, like in the EU, would be submitting documents with the wrong info to the authorities. This means the wrong substances are being registered and could affect whether that vendor can sell those cells if the MSDS issues are discovered. I suspect that would be less than good news to the vendors.
If you believe the MSDS is accurate then QSO is using the same chemistry as LiPo’s for these cells. With all of the other cells we can buy though why would we buy ones that use the same chemistry as LiPo‘s (with its increased volatility)? If the MSDS is not accurate, and these cells are rewraps, then QSO needs to explain why this safety document says they are LiPo’s. Either way, this earns this QSO cell a Do Not Buy recommendation from me.
Two cells were purchased for the purposes of testing by me.

I want to work for the vaping community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability and testing news and a say in what I test then please consider becoming a patron and supporting my testing efforts: https://www.patreon.com/batterymooch
These tests only note the ESTIMATED ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” batteries or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
Any rating in my ratings tables can change at any time as different grade cells appear on the market, we get swamped with fakes, or new information becomes available to me. Please, never assume that the ratings in the tables are permanent and will never change! Always download the latest version before considering any cell purchase.

Hi Phil,
I just want to congratulate you on your 10 year vape anniversary. That’s huge.
I am looking forward to mine November 14th 2020.
The first mod if you want to call it that was a stick mod i think it was 3.7 volts. No variable volt. It was kind of hard to quit with that because I could not get enough nicotine not enough power. I remember when the twist came out I was thrilled. I could vape up to 6 volts which was a huge help. But I stuck with that stick mod until something more powerful came out. I feel so much better.
I have had chronic bronchitis all my life. Since I started vaping I might get one attack a year instead of two or 3 which is huge. But back to you.
Thanks for being there for me and everyone that you have helped over the years. You have no idea how much I appreciate your help. I am getting ready to order my Zlide and hope to use it on my Innokin Cool Fire IVs. I have 6 of them. I get just what I want out of it and I will use a 1.6 coil i think. I plan on buying 2 Zlides a month until I get 6. I love the look of it and have watched your video several times.
Thanks again Phil.
Sincerely, Susan

Dear Phil,
I’m so sorry it’s taking me this long to get back to you but unfortunately I’ve been extremely sick. We received your prize pack last week sometime, we opened the package…..Phil you spoiled us, and surprised us as well you sure know how to make a girl cry.(happy tears) you really didn’t have to give us that Innokin EQ on top of everything else you already had, thank you so much it’s extremely overwhelming and yes I’m still shaking. You are such a kind and generous person and trust me when I say that I/we will NOT smoke again, I am a non-smoker thanks to you. You have help with providing the tools needed to do so and to find the perfect vape. Thank you from the bottom of my heart.Sincerely
Cathy

Congratulations on 10 years. I’m at 7 at love it.
The beautiful smell of rain & clear lungs after too many years of smoking, thank God for vaping. I’ve been converting smokers by just buying them ecigs.
I wish vaping technology had come out years ago. Sure made quitting smoking easy. The smell of cigarettes, disgusting.
Thank you for keeping up the fight for vaping & all your guidance & support.

First hospital vaping shops to help smokers kick habit
Think about it…
Here in the good ole USA we are fighting flavor bans, vaping bans, bad main stream media stories and commercials, taxes taxes and more taxes yet across the pond they are opening up vape shops IN HOSPITALS attempting to help people quit their smoking habit and lead them to an least a 95% safer way to get their nicotine.
Ironic isn’t it?
From Michael
I wanted to say thank you for your smokers show and all your reviews. I’m 44 and been smoking for close to 30 years. I have tried switching to vape several times over the years and just hasn’t worked for me, until I found your show. I thought my only options were big sub ohm tanks and low nic because that’s all I see out there and none of that worked for me.
I just bought a Smok Nord and 12mg Naked 100 juice and so for I love it! Next week I’m going to order your Kroma A kit with the Zenith tank and really looking forward to giving it a go.
Again thank you and the Greek for all you guys do!
Have great day and keep up the great work.
MY INNOKIN ADEPTS ARRIVED!
I’ve posted about this device, but I finally have the retail package in my hands and I’m very pleased.
The Adept takes the shock and waterproof concept and makes it simple.
The device is paired up with a Zlide tank and will automatically sense which Z-Coil you’re using and adjust the wattages ranges accordingly.
If you’re using the 1.6 Ohm coil you’ll get : 11, 12, 13, and 14 watt settings.
If you’re using the .8 Ohm or .48 Ohm Plex 3D you’ll get: 14, 15, 16, and 17 watt settings.
I’ll probably do a show and tell on this shortly.
In the meantime, here’s some of my own photos along with the device flyers again.
Enjoy!

From Kevin
Just want to reach out and say a big thanks for all have done and continue to do for the cause. I started with your vids a few years back and almost quit cigarette’s for good. I started vaping the sub ohm tanks and lost my way with the low nic juices. I since found my way back by watching Matt from SMM and then wouldn’t ya know good ole Pete Pbusardo. Got me a Zenith today and some 8mg juice. This is the way to never buy another pack. With that tingle on the back of my neck, THANK YOU.
