I bought a box mod that was probably overpriced but I was in a pinch. It looked decent enough and I felt like I might as well get something rather than going back to ciggies. I know a lot of people's goal here is to quit nicotine, but I honestly just admitted my defeat and went forward feeding that addiction as safely as possible (or so I thought).

Long story short, the device is a voopoo drag and it came with batteries that the local B&M provided. I don't like giving out brand names because of reasons, mostly to do with being mislead by "reviewers" early on, but I did include the most pertinent ones because I was worried about safety. If this was in error, I hope that it can be edited/rectified to what is most useful to answering my question.

My questions are thus:

First, is the circuitry / programming on the device I bought of enough quality to find it "mostly harmless"?

Second, the batteries given by the local B&M have a decently constructed look with no obvious "knock-off" vibe, but I know that doesn't mean a thing so I'm hoping someone can provide me with a most recent link to information regarding them: The top line says US18650VTC5 C5, the second line says G 1769861AA06A, the third line says MURATA INR19/66. It is what can be safely assumed to be below the wrap on the battery, with a QR code on the wrap itself. I have tried looking into the batteries and I have found that they are at the very least a knock off brand of Sony 18650s. I've tried to look into it but sometime after the Earthquake/Tsunami in Japan, they were supposedly discontinued. I also understand that certain countries will abuse lax laws to make money unscrupulously. It is a muddy area because I understand a business wanting to distance itself from a vape-mod community. User error and lawsuits from that would be something I would want to avoid as a business owner. The information regarding the label does not match up with what information I can find that would put my mind at ease.

Third, I'm also worried about the B&M providing these batteries if they aren't of good quality to people who are new/inexperienced in the vaping world with every device they sell.

I'm trying to follow a guide I found by Mooch about purchasing a set of trusted/trustable batteries but it is fairly daunting as this is an area that I never expected to go when I first started out vaping. Ironically, I didn't spend as much time worrying about the possibility that the internal battery of my previous device could catastrophically fail... but did take caution as to charge it while I was awake and inside of a containment box.

I apologize if this question is answered previously, but I did use the search terms I could think of to answer it in a relatively short period of time. At the moment, I'm taking care not to vape too rapidly, and I'm also taking the precaution of removing the batteries when I am not vaping.

Additional notes: I'm using a uwell crown v1 with a .25 ohm dual coil at 60 watts. I'm currently researching the safety of this setup while I await responses. The mod I'm using has two matched 18650 cells with the previously described attributes.

Again, I apologize for a possibly repeated question and also for the longwindedness, as well as any taboos I might have made in this post. Understand it was unintentional. The only way to learn is to seek information.

There's nothing wrong with a Drag mod. Like any massed produced device a manufacturing defect is possible, but aside from that you're good to go. I don't have one so I can't comment personally, but a lot of people do and I am not aware of any outstanding problems. Some people like the proprietary chip set in the machine as it is highly adjustable; others not so much.

Batteries are another matter. Any chance you can post photos of the printing and the top and bottom of the cell? Those might help us identify what you have. Or maybe not. The right way to make certain you are getting the batteries you're paying for is to buy only from a trusted vendor. Take a look at Mooch's chart; you'll find a list of the same down toward the bottom. I buy mine from RTDvapor, but I have used others who are also good.

The thing about batteries is all of them are safe if safely handled, not shorted and used within their CDR limits; and if not none of them are. The problem is you can't tell by looking what those limits are, and they vary over the life of the cell, and with temperature and so forth. Your Drag is a 157 watt mod with two batteries. Any quality 20A CDR cell-- they're legion, too many to name, look at Mooch's chart-- will do very nicely in it. The VTC5A is probably overkill; I might have gone with the LG HD2 or HD2C, or the Samsung 25R instead. Of rather more importance is how you vape it. If you're chaining it at 157 watts, you need 20A cells, and the VTC5A is not overkill. If you never see the upside of 50 watts, you could get by with 10A cells (I am not, and do not, recommending 10A cells for vaping under any circumstances; get 20A cells minimum for all purposes).

Ping me back with photos, if you can conveniently get them, and more info about how you vape. Right now, just stay under 50ish watts and don't worry.

No one here, including @battery Mooch, will be able to tell you if your batteries are authentic Sony batteries, even with a pic. Mooch might be able to tell if he could bench test them, but he is overwhelmed with other requests and projects.

Best advice anyone can give you is to purchase from a known trusted battery supplier. Even they will rarely receive a shipment of counterfeits, but the good thing is they will replace or refund the purchase once they find out. Now, try getting a replacement or refund from a vape shop, Ebay, or Amazon --- it probably would never happen.

My standard lecture on which batteries to use in a regulated mod is as follows:

Are you using a single, dual, or triple battery mod? In the interests of keeping things simple:

-If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.

-If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, you're good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.

-If you use a single 25 amp CDR battery like the Sony VTC5A, then you are good for 75 watts per battery, 150 watts for two batteries, and 225 watts with three.

-If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts.​

Yes unfortunately there is no magic test, which is why buying from reputable vendors matters. As to your vape shop they may (knowingly or inadvertently provided you with "seconded" batteries that may have failed the Qc from the manufacturers, or rewrapped cells.

Or they may be totally genuine and whatnot, but there just isn't a simple way to tell. Gear is far harder to sell clones and etc., due to the fact that there are things like authentication codes. I'm pretty sure your mod will be fine but to be on the safe side you should purchase your batteries from reputable vendors. Best of luck,

It sounds like you've got a good plan to go with. Your batteries are (or are claiming to be) Sony VTC5s, which are 20A batteries as you can see on Baditude's post above. They say Murata instead of Sony because Sony sold its battery division to Murata, so all the cells we're still calling Sonys are currently being produced by Murata. If they are what they claim to be, they're perfectly good batteries that can safely provide up to 120 w (together - 60 each) on a regulated mod. Baditude's post also lists the limits of a bunch of the most common batteries, but if you want to know where those figures come from or calculate it yourself, I'd recommend this post by Mooch.

Unfortunately, there's no practical way to tell for sure whether the batteries are genuine or counterfeits. You appear to have correctly concluded that your best bet for avoiding counterfeits is to buy from reliable vendors. Good luck!

    Could you post a clear picture of the battery showing the printing? With your permission I’d like to use it and post about the Murata VTC batteries now that they have finally reached the resellers who service our community.
