Battery Charging Question

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...  

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?  

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  

Hey guys,

I finally updated my charger a few days ago (I think before I had the VP2) or something like that. Quick question on something I'm noticing that seems a bit odd to me.

When I charge (for example 18650's), a battery that's fully charged in channel 1...it flashes FULL/0.00 mA, I remove the battery. A few minutes later, I'll put the battery back in the same bay, and all of a sudden there are a few hundred mA's that show up on the screen that need to be charged back into the battery and it takes a few minutes for channel 1 to recognize the battery is fully charged and flash FULL/0.00mA again (although it does show above that's fully charged at 4.2v).

If I take that same battery and do the same test but this time in channel 2, within a few seconds it recognizes that the battery is fully charged and flashes FULL/0.00mA. So it seems channel 1 is not working as well as channel 2 is, when it comes to recognizing information from the battery.

Is this normal for this charger or do I have a defective charger?  

Is it safe to use the vaporesso revenger (built in batteries) and the vaporesso revenger mini (lights up) after owing it for three years? It seems to have kept 3/4 battery charge and I have not used them in a year and a half. I ask because I’ve read older batteries can be dangerous to use if they have low voltage or something.

Also is it safe to use Sony lithium ion batteries after 2 1/2 years? Their volts was at 3.6 when I started charging them. I haven’t used them in a year and a half, but I did charge them once during the year. Using them in arrow sense mod.  

anyone know of one that exists? I want a box mod that can go up to 100-150 watts but want one that has internal batteries that I can charge via usb cable or ac adapter

I was looking at the segelei and ipv3/4 but I don't want to change batteries

the reason is I travel sometimes for my job up to 2-3 hours and I don't want the hassle or danger of changing batteries while driving
I want something I can vape on for a couple hours without worrying about replacing the batteries

I sub ohm at .2 ohms and bought the arctic tank .2 ohm coils specifically for this reason

thank you

p.s. I found this: MEGATRON 260 watts 5400mAh box mod uses ac adapter to charge but looks really weird and no one has tried it yet so I'm a tad skeptical  

Hey all,

I've been using the Intellicharger I2 for a while, and recently I've noticed it's taking a long time to charge batteries. Keep in mind I realize that the Amp output is distributed across two batteries, etc, but I feel as though its time for an upgrade.

I regularly use Samsung25R's and occasionally VTC5's, (18650) and I was wondering what your opinions are on the best charger I can buy. The criteria I'm looking for ideally a

External transformer
Fast charging time
LCD screen
Ample venting
Autostop cuttoff when batteries finished

Thank you in advance!  

Hi, I'm new here and have searched but couldn't find an answer so help appreciated. When charging my MVP4 no matter what the state of charge when I put it on charge the button shows RED. It stays RED and as the charge builds turns GREEN and then goes out when full. I.e. It never goes through AMBER which all my previous batteries have. Is this normal?  

Hi
I just got a Xtar VC2s charger for my 21700 batteries (Samsung 40T).
Chose that charger also because it "charges at safe low current".

When it charges 2 batteries, it's at about 1000 mAh for each battery. All good.
But when charging only one battery, it charges it at 2000 mAh. Hmm?

I assume 2000 mAh is still "safe".. But won't that reduce lifespan on the battery?

The charger manual says "when the power supply is insufficient, the charger will reduce the charge current correspondingly".
So maybe I should get a usb power supply with like 1000 mAh output?

I will only be charging one battery at a time, and prefer charging slowly if that gives more safety and lifespan.

But I don't know if charging at 2000 mAh is really an issue..  

I've been charging my 18650 batteries on a Nitecore charger but having to unscrew my Smok XPRO m65 is a real pain so thought I may as well make use of the USB port and charge the battery while it's still in the mod.
But I've been hearing a few horror stories of other mods such as the clouper, apparently its not safe to charger using the USB port

I'd really appreciate it if anyone can help inform me if I'd be able to use my phone charging adaptor with my mod.

The input and output specs of my phone charger and mod input are in the attached pics.

Cheers everyone
