Worried About Battery

Hey guys, so I noticed a few days ago that my ecig is making a high pitched squealing noise. I've located the source to be the bottom cap of my mod. I noted that it only does it with one of my 2 batteries. It doesn't affect my vape at all but I would like to know if this is somthing I should be worried about.

My set up is,
innokin itaste 134
iclear 30 X.I. clearomizer
2 mxjo 18650 batteries.  

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?  

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?  

Hi Guys,

So I originally had a nitecore i8 charger that I used to charge 8 x 18650 batteries. After using it for a few days I started noticing that it made a weird ticking noise and got VERY hot on the bottom. Needless to say this made me quite uncomfortable.

So I exchanged it for a Xtar VC8. So far it’s been amazing. No ticking or weird noises and it doesn’t get hot. It also comes with a nice screen that shows you some details about your batteries. This is what leads me to my question.

I noticed when charging my batteries most of them show as roughly 3.7v but others show as 4.1v. Also the longer they charge the higher the number goes. Is this normal? Sorry I’m a total idiot when it comes to batteries and voltages etc. If anyone could clue me in i would be very great full!

Thanks  

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!

Vape Happy,

Hi everyone,
Hope your all having a great weekend! Hopefully someone can help me figure out any good canadian or American reputable vendors for 18650 batteries for my arrow sense mod. Out of all the vendors listed in the battery thread, only one had the batteries I wanted, but it was in the US and would cost over $50 for shipping. Hoping to find shipping for $20-30 canadian instead. I am particularly interested in the batteries on the forums listed as tested by mooch in a stickier post. Or Sony battery with 2500 mah , I like to vape with two 18650 batteries at 60-80 watts.  

Hi guys,
I would like to try more models of batteries, 18350 - 18500 - 18650.
Beyond AW, that I use usually, what other batteries can I try?
I use only mechanical mods, resistances from 0.8 to 1.5 ohm.
Thanks for the help!  

will 2 mxjo 18650 batteries in my ipv3 be able to handle a .2 ohm coil, im thinking about buying the new arctic tank.  

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.  

I've seen a few discussions on this in the search but none quite answered all of my questions. (most were about juice,18650 batteries, or domestic flights with 1 device)

I haven't flown internationally since I started vaping. I'm just wondering how/where to pack everything. I'm flying from the US to Italy via Russia. I'm going for awhile so i'm taking almost everything. For Juice and tanks/coils i'm just going to pack them in my checked bags. What i'm more worried about is what to do with batteries. All of my devices are internal batteries (istick, twists) so is it better to turn them off and take off the tank and pack them in checked? Or is it better to carry them on? I have quite a few (+ a friend's stuff) so i'd hate to carry them on but i'm worried they might get damaged because it gets pretty cold down in those luggage compartments. If I carry on them on do I have to take everything out for the security check like you have to with laptops and ipads? Is it better to keep tanks on them so TSA knows what they are or are they getting pretty familiar with what this stuff looks like. I don't want anything confiscated obviously but I can see how they look a bit suspicious without tanks.
