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?

18650 Batteries

Hi I just got a sigelei 100 watt plus and this is my first time using freshly charged batteries in it... it's still reading at being 100% in the sigelei. ive been using it for maybe 3 hours total . Is this normal .. because its starting to make me wonder if something is wrong. Its been at 40 to 50 watts this whole time. I didnt charge the batteries at first when i got them because my charger did not arrive yet...then once it did come i charged them and now its continuing to stay at 100%  

Efest 18650 (purple) Questions

Hi folks,

I recently purchases a Sigelei 100w box, and got the purple Efest batteries that the vendor recommended.
I'm using this with a KangerTech Subtank Mini.
It's currently set to 42W - 5.0V, and the resistance it shows me is 0.6 ohms.

I have some questions about my setup.

- I read some reports that these batteries have different specs than what is reported, and it could potentially be dangerous. What should I do to be safe? Is there a max W/V that I can set it to?
- I have a TrustFire TR-001 charger (output: 4.2V / 500Ma). Can I charge those batteries with that? I read the charger supports 18650 batteries, but I'd rather be sure...
- If the charger is no good, any recommendations of what I should be using?

Thanks a lot!  

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...  

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  

Battery Revival

Herro!

So, I always used to use mech mods from about 6 months to a year and a half into vaping. For the last 6 months I've been on regulated (iStick 30W and 50W).

When I switched to regulated I retired my mech mods and 18650 batteries to the closet. I made sure they were all around 50% charged because I heard from someone on here that was the best condition to leave them.

Well recently I've had this curiosity to try them again, only for at home use, mainly for the novelty of it.

So, my question is, what will I have to do to revive these batteries? Are they safe to just throw back on the charger and use when fully charged? Or are they not safe to use?

Batteries: 4 Sony VTC 4's (all were acquired about a month before I stopped using mechs), 2 XTAR (Sony) VTC 4's (about a year old now) , 2 MXJO 2500mah (20A LG's) (about a year old now).

Let me know! Thank you!

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?  

Has Mooch Blessed Any 3.7v 18650's?

I am interested in setting up an Arduino charger for my vape batteries. But the charger I want to use, an Adafruit bq24074 solar charger, does not support nominal 3.6V batteries. And basically all the Mooch approved batteries are nominal 3.6V. So, which 3.7V batteries are considered fairly robust for high current, vaping purposes?  

Charging 21700 Battery At 2000 Mah

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..  

Xtar Vc2s Charger Question

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?
