Battery Authenticity and Safety

[Hijazist]

I am new to the forum, but I've been reading it a lot lately and it's been invaluable in our vaping experience.

We got an Aspire Skystar for my wife (it was on sale for $17 at VaporDNA), and she loves it. We installed two brand new and fully charged Samsungs 25r's we got them Fuggin Vapor along with 10 others. The charge on the batteries is draining very fast at 75w (about 8 hours), and at the same time, they're not draining at the same rate. A couple of questions:

- Is Fuggin Vapor a trusted battery seller? I checked all of Mooch's fake battery signs and none apply to ours, but that doesn't exclude the fact that they could be rewraps.
- Why are the batteries draining fast and unevenly.
- Are these chargers considered reliable ones?
Eastshine S2, Nitecore Intellicharger i2
- Finally, the amp display on the mod reads 17-19 amps at 75w, is this the current being drawn from both batteries or just one; or is it irrelevant to the actual current being drawn from the batteries?

I apologize for so many questions in a first post lol, but safety comes first

Im no wiz with batteries mind you, but I use 25rs myself, however im using them in a series device and your sounds like parallel? I know the Nitecore Intellicharger has been recommended as a solid and reliable charger. Ill try to dig up some more answers for you myself. Always eager to learn when its something im iffy on.

I do know that 17amps at 75w would put your resistance/ohms at .25 does that sound right?

edit: Im quite certain that it is normal for mods to drain/rely on one battery faster then the other.

My wife also has a Skystar but is using TC mode in the 20-30 watt range so much longer battery life. 8 hours may be about right depending on how much it is used in those 8 hours. We haven't noticed batteries discharging unevenly. We also use the Nitecore i2 charger but I have never used an Eastshine.

I have never heard of "Fuggin Vapor" but that doesn't sounds like a name I would trust.

I would suggest getting a volt meter and measuring the voltage of the batteries when they first come off of the charger to see if they are actually charging to full. I would also measure them when you pull them out of the mod to see if they really are discharged unevenly. It could be that either the charger isn't charging them evenly and fully, or that the mod is displaying the discharge incorrectly. Measuring them independently with a multi-meter will help determine where the problem really is.

The 17 amps is what is being applied to the coil by the regulating circuit, not what is being pulled from the battery.

your sounds like parallel?

The Skystar is series as well.

75 watts, what is the resistance of coils? For my personal use, 8 hours steady use sounds great. I generally use lg hg2 batts and they have more mah than the 25rs, and go through 2 pairs a day at 77 watts,.25 ohm.

 

[uthinkofsomething]

As far as Fuggin goes, I hate their juice, though it is cheap. I would not 100 percent trust their batts to be genuine but likely they are and you are just not used to what is normal for your mod.

Thanks a lot! The batteries are opposite so I think they're series. The build is 2.5 indeed.

That's very helpful. I'll look into getting a multimeter.

Our build is also.25 ohms, so I guess the batteries are discharging fine.

Yeah, I saw the sale of 10 for $35 and I went cheapo lol.

 

[uthinkofsomething]

Yeah, I so the sale of 10 for $35 and I went cheapo lol.

Chances are they are legit batteries and Fuggin may be fine to get them from. Really good places to buy batteries from with the least doubt to their authenticity are Illumn.com, Orbtronic, IMR, there are others. Keep your battery selection to LG, Samsung, and Sony, which you have, and you will be better off.

If you haven't done so already watch Mooch's videos.

He has an YT page, posts here regularly, has a blog, etc. Mooch is the definitive word on batteries. He lists trusted suppliers in his videos.

He does extensive testing on batteries then reports the results here.

8 hrs is about right, especially if youre vaping a lot as one would in the beginning of vaping.

Hi Hijazist. Welcome to the ECF.

Here's my thinking on Not Buying Fake Batteries...

It's Very Difficult for the Average Person with Average Battery Expertise to know if the Batteries they have are Real or Not. So someone like Fuggin Vapor usually has to rely on what their Battery Distributor tells them.

Very Few Retailers will Intentionally Sell Knock-Off or Rewrapped Batteries. But the Simple Fact is Most General Retailers don't know if their Batteries are Real or Not.

Whereas a Company that Only Sells Batteries will have a Means to do Random Testing of the Batteries. And tend to deal with Better/Closer to the OEM Distributors.

If Joe Blow Vape shop Knowingly or Unknowingly sells some el-Cheap O cells rewrapped as a Quality Battery, ehh, it happens. It probably Isn't going to Ruin them. But if a Company that ONLY sells Batteries gets a rep of selling Fake Cells, they will pretty much be Run Out of Town on a Rail.

Mooch has a List of Battery Suppliers he Recommends as Reputable. I would suggest getting your Batteries from one of them.

 

[untar]

the amp display on the mod reads 17-19 amps at 75w, is this the current being drawn from both batteries or just one; or is it irrelevant to the actual current being drawn from the batteries?

It is pretty much irrelevant. Think of your regulated mod like this

[power to atomizer]<---[black box mod]<---[power from batteries]

=> power from batteries equals power to atomizer (minus losses in the black box but let's ignore those for simplicity)
That means the amp draw from batteries isn't constant, in fact it increases as the battery voltage decreases, eg a battery at 3.7V supplying 40W puts out
40.0W/3.7V = 10.81A
and the same battery at 3.2V supplying 40W puts out
40.0W/3.2V = 12.5A

So to keep the power output constant with a sinking supply voltage the current must increase. What your mod shows you on the display is just the current rushing through your coil, it has nothing to do with the batteries.

I truly have no way of knowing whether your batteries are genuine and probably neither does anyone else. It's almost impossible to tell by "usage patterns" as everyone vapes so differently including resistance, length of drag and everything else.

I'd recommend if you only got a pair of batteries, to get some authentic batteries from trusted vendors (you can find this on Mooch's blog the last cell of his table). Batteries are relatively inexpensive compared to plastic surgery and honestly some of the authentic suppliers have better prices than Vape emporiums.

It's simply not worth the risk, in my opinion I mean we could debate for hours whether they are genuine but you will not know with real certainty as you will with an authentic supplier.

Vaping involves a certain amount of purchasing errors especially early on, and I have made my share. Risk-reward here really makes me thing you should pick up some batteries you KNOW are authentic. Worst case, in a regulated mod protections kick in but no protection is 100% reliable 100% of the time. Good luck,

Anna

Coil resistance is applicable only with mechancial (non-electronic) mods. With regulated mods, coil resistance is irrelevant. What matters most when choosing the batteries for regulated mods is the highest wattage setting you use and the amp rating of the batteries (see chart below).

Checking battery voltage coming off the mod or in the charger, one can use either a digital multimeter or a charger which displays battery voltage.

WATTAGE PER SINGLE BATTERY on REGULATED MOD:
(Total wattage doubles using 2 batteries; Triples using 3 batteries.)

Up to 45W:

Samsung 18650 30Q, 3000 mah 15 amp CDR

Sony 18650VTC6 3000mAh 15 amp CDR

Up to 60W:

LG 18650HG2 3000mah 20 amp CDR

LG 18650HE4 2500 mah 20 amp CDR

Samsung 18650-25R, 2500 mah 20 amp CDR

Sanyo UR18650NSX, 2500 mah 20 amp CDR

Sony 18650VTC5, 2600 mah 20 amp CDR

Sony 18650VTC4, 2100 mah 23 amp CDR

Up to 75W:

LG 18650 HD4 2100 mah 25 amp CDR

LG 18650 HD2 2000 mah 25 amp CDR

Samsung 18650-24S, 2500 mah 25 amp CDR

Sony 18650VTC5A, 2500 mah 25 amp CDR

Up to 90W:

LG18650HB6 1500mah 30 amp CDR

LG18650HB2 1500mAh 30 amp CDR

LG18650HB4 1500mAh 30 amp CDR

Samsung 18650-20S 2000mah 30 amp CDR

You said you were using 75 watts in a dual battery mod. Using 2x Samsung 25R batteries you're good up to 120 watts with 5000 mAh capacity. If you used 2x Samsung 30Q batteries you'd be good for up to 90 watts with 6000 mAh capacity. You may get longer use if you went with the Samsung 30Q.

-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.​

This actually makes sense. In the future I will definitely follow Mooch's supplier's recommendation.
