Mod Acts Up With Certain Batteries

Is there a logical reason why a mod would just randomly shut off very frequently when using one brand of battery and do it much less often with another? And this isn't a situation where I'm only referring to a single battery this is any battery of one type doesn't work well and any battery of the other type that I've tried does. * this is a long post if you don't want to read the whole thing you could just answer that question and that would provide me with a lot of information

My snowwolf mini mod which is the sigelei product not the original snowwolf is having a fairly common issue where occasionally the whole device just turns off. Then you have to loosen the battery cap pull the battery out so it's not making a connection and then put the battery back in and it turns back on. I've seen this reported multiple times. Now when I was using Samsung batteries it was really bad like I would get maybe two Puffs before it would shut off. But with LG batteries it seems like I can use the product almost like normal. Like I can get a good half day usage out of it before it has a problem and then I take the battery out put it back in and I get another few hours.

I know that there is a slight variance in size between these batteries or at least it seems like there is because my drip box gets the Samsungs stuck in it but not the LG which I solve by taking the stupid sticker off of them not the wrap the sticker.

Now I've only had this for 31 days so while it is past the stores warranty it's not past sigelei or snowwolf. I'm debating on whether or not I even want to worry about this warranty situation because if it continues working the way it is as long as I use LG batteries I would rather not take the chance of getting a much worse product. I feel like it's going to be hard to get them to warranty it and at the very least I have a month or two to figure this out.
My question is why would it do this why would it work so much better with one kind of battery and be nearly unusable with the other and also like why would it do this in the first place at all why would it just randomly shut off the batteries are good it's definitely the mod my first thought would be that there's a short but why would one battery cause a short and not the other or at least not as frequently?

I've had such bad luck with sigelei products that I honestly believe if I try to warranty this they're just going to send me a broken device LOL how does that work if they send me a broken device can I warranty that product? Do I get another 90 days? Or do I get the rest of my warranty period carried over from the first device? Or is it a situation where you only get one warranty and then if a device breaks again you're out of luck

Snow Wolf/ Segelei Warranty

I have a snowwolf mini by sigelei kit and the mod has gone Haywire one day after the retailer warranty ended. My question is which warranty service should I contact? Sigelei is the parent company. Snowwolf is the branding that they're using I guess for this kit. Both sites have their own warranty contact information and I'm not sure which one to contact the little warranty card mentions nothing about the snowwolf but on the sigelei site the authenticity check does not work only on the snowwolf site so I don't really know which one to go through. If anyone's had any experience with this that would be great. I've heard mixed reviews but I would like to at least attempt to warranty this product seeing as how I've only owned two sigeleis and both of them went bad with in 31 days. It's worth a try anyway  

Best Deal On High-end Batteries? Who Knows Where To Look?

So, I know that the Sony VTC batteries were the like "Go-to" battery. But they are being faked a lot and are hard to come by some authentic ones.

So whats the next best option?

I have a few different batteries and I definitely can tell the difference in the quality of the hit, and the life of the battery.

I have a red IMR 2000 mAh 18650 and it hits the worst out of all of my batteries.

Then I have a blue samsung battery (Can't really read the writing) but I can see it says 25r on it. This one hits decent.

Then I have a green 2600 mAh battery. Its a beast. Hits like a champ and lasts long. I would like to find a similar battery to this one. Im guessing this is the Sony VTC 5.

I really want to find something that is just as good as the Green one.

Does anyone know where to find these or a similar battery that is 2600mAh 30 amp? If so, are there any deals going on online where I could get a good price? Id like to order some new batteries.

Thanks for the help all!


Edit. One more question. Anyone know the difference between the Amps on each of the batteries? Just from guessing id say the red is 20 amps, blue is 25, and the green is 30? Does that sound right?  

Efest 18650 Batteries Not Lasting!!

So I have (2) 3100mAh Efest batteries rated @ 20A and (1) 2500mAh Efest batterie rated @ 35A. I'm experiencing a pretty annoying problem with all 3 of them and that is they aren't lasting nearly as long as I feel they should be. I can EASILY vape through a battery in less than one hour while heavy vaping. I'm aware that I am sub-ohming and that requires more power from the battery but these are just going way too fast and something isn't right. I have a BEC Pro mod that takes a single 18650 battery and I'm vaping an Aspire Atlantis tank @ 35 watts with the .5 ohm coil installed. I charge each battery fully with a Nitecore i2 before using them and it'll say 4.2V on my mod & on my Smart BEC app it will say 100% as I take my first few puffs but then starts draining at a ridiculous rate until they are dead. I am not aware what the mod efficiency is on my BEC Pro or if there might be something not working properly within my device. Can someone please help me find what's wrong with these? Maybe some of you have eperienced this problem with Efest batteries in the past? Thanks in advance!

Edit: These are genuine Efest batteries as I bought them straight from the manufacture on Ebay.  

Some Series 18650 Questions

I bought my Sigelei 100w Plus a few days back and ordered 2 Sony VTC4's on my same order (I'm confident they're legitimate, I've bought some before) to be able to marry them together and use them with my Sigelei. Upon receiving the batteries, I labelled one A, and one B and put them into my charger at the same time (charger was off, put both in and turned it on), one battery is slightly more charged than the other (it's 2/3 bars, while the other is still 1/3). I'm a bit worried about using married batteries, I understand rotating A and B in my Sigelei and charger but will they be the same charge when they're done? They're new batteries and they both went on at the same time yet one of them is charging a little bit faster.

When both of the batteries are fully charged, will they be safe to use and cycle accordingly? I heard about if one battery has even a tiny bit less, the batteries will take an uneven load and it will make it risky. How do I ensure that these batteries remain married?  

Ego-t Battery Not Screwing Into Charger

I ordered two of these batteries from FastTech. The cheap price and high capacity (without having a mod or some awkward huge battery) attracted me to them. Some two weeks later they show up...

I have two Puff King chargers that came with starter kits we bought at a B&M store. We've been using them with Tripl3 eGo batteries, one Puff King battery (and another Puff King battery, which was taken back and exchanged for another eGo-T battery, which broke), and so far no problems screwing any batteries in. These two from FT show up however and neither will screw into one Puff King charger, but they both did into the other (same charger, down to the model number and everything). Now, one battery from FT still screws in, but the other doesn't.

I took the non screwing in battery to a local B&M store and the guy there was able to screw it into one of their chargers. He handed it to me, and I unscrewed it, screwed it back in, unscrewed it again, and then neither of us could screw it in again. Now I have one battery from FT that will screw into one of my chargers, but not the other. The other battery will charge, but it has to just like sit in the charger and hope the connection stays okay for it to charge. I still have no problems screwing any of my other batteries into either charger, just these ones from FT. Also, it's worth mentioning that the FT batteries never seemed to screw in right... it always felt weird and finicky getting it to go in.

What's up with these batteries? They claim to be eGo/510 threaded, just like my other batteries. They look just like my other batteries too, except they won't screw in right...  

Vape Device Number 21 Not Working.

One of you guys suggested the Voopoo drag x when I discussed my 20th vape device no longer charging through the USB mini. It was a Geekvape which they claim are indestructible. Of course they don't mention how the USB port is a cheap piece of garbage that will eventually fail even when treated delicately. I received the Voopoo drag x in the mail a couple days ago. I didn't realize it doesn't come with a battery so I picked up an IR18650-25R 20A 3.7V battery at a local vape shop. It was working beautifully for about a half hour and then it would just turn off. Even if I pushed the buttons or clicked five times, it wouldn't power up unless I took out the battery, put it back in and then clicked five times. Then I would get a few puffs and it would turn off again. Then today, I started receiving a message that said "atomizer short". I kept getting this message over and over even if I took out the coil and put it back in. Occasionally, it would start working again, but between the device powering off and the atomizer short problem, it's more or less unusable. It was only about $60 in total so no biggie. So now I'm shopping around for my 22nd vape device. Does anyone have any suggestions?  

Battery Reading Fluctuates

Okay so I did look this up and it appears that other people have mentioned this specifically with sigelei mods but I didn't see any that were more recent. I look at my mod to see what my batteries charge looks like to see if I need to go ahead and change batteries and I swear to God the thing starts jumping around as though the batteries are charging themselves and then going back to the 40%. Apparently that's a problem that the mods have and isn't something to be concerned about but it freaked me the heck out. They're doing just fine now that they're in their external charger thingy but I just want to make sure that that's not a sign of something going wrong with the batteries that it's just my mod being weird I've checked the connections and everything to make sure it was clean and that the batteries were fine and not dented or unwrapped and everything looks good. I just need some assurance that the batteries were not like failing or that a regulated mod would shut itself off if batteries were jumping around like crazy in reality if that's even possible
For clarification it was doing this when I was not firing it  

The Possibility Of An Ego Type Battery Charger Mod

Just curious that if I could build a device that would allow me to connect an eGo or Vision Spinner 2 type battery to a charger like a Nitecore Intellicharger i4 that it would work safely and efficiently in place of the usual USB charger? I have an idea as to how to make the connection but I wanted to get some feedback on the idea before I actually proceed to build it. I admit that I am no expert when it comes to Li-ion batteries but my goal is to be able to charge the "stick" type batteries that I own in a faster and safer manner than the seemingly low tech USB chargers. Thanks for any input offered.  

Another Question About Batteries.

Now that I have gotten into unregulated mods I've been doing a lot of reading about batteries... well actually I had started reading before but now that I am actually using them I want to know more.

One thing I am a little puzzled about is that you should recharge a battery when it's about 2/3 discharged and you should never charge a battery that is completely discharged. My questions:

1. How do I know the level of discharge in my battery? - I don't own a multi meter
2. What do you do with a fully discharged battery? - just chuck it?  

Geekvape Aegis X Zeus Battery Problem

So I just bought a kit, it doesn't come with batteries -- which I wasn't told (was led to believe it was charged through the USB port according to vape store employee). So I ordered x4 Nitecore-NL1834 18650 3400mAh 3.7 Protected Lithium Ion (Li-ion) batteries and now the door won't close. I read an old article saying that Protected 18650 can be bigger. If there's a possibility of buying batteries that cost $18 a pop shouldn't they let you know there's a chance that it won't be the right size?
Is there a trick to getting the battery lid to close or do I need to now buy unprotected 18650 batteries and hopefully get my money back on the protected batteries I bought?
