Battery Question

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, so I have several different brands of 18650 batteries but I'm getting ready to pick up the new Geekvape Aegis X, I wanted to get some new batteries. I have been reading up on it but I'm so confused, I don't vape very high wattage It's always under 50 watt, 45 usually being the most, so what would be the best batteries for long activity? Any input would really help. Thanks  

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.  

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?  

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.  

Hello

Haven't been here in quite a long time but I have a question.

I have had a good supply for batteries for about a year now and have bought batteries from the same place... rtdvapor since I started vaping.

Batteries are getting old, looking to get new.. but when I go to rtd it says it is unavailable.

So I guess I have 2 questions.

Anyone know if rtd vapor is still in business? and if not anyone know a reliable place I can go for batteries?

Thank you all in advance!  

Just bought a brand new pair IMR 18650 2500mah batteries, when they start getting low and you're getting late fee from batteries did you take them out and charge them or let them drain completely, the mod shows a little juice left in them but I'm getting a very light vape.  

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?  

Hi guys, just had a quick question. I'm not sure if there is any problem here but I recently bought some mxjo 18650 batteries, they work great. but my issue is that on the bottom of one of the batteries there's a small indention. The mark look likes it's from the pin on my mods end cap. Should I be worried about this or is this normal?  

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
