18650 Battery At 13 Watts

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 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?  

Can I use an external battery pack to charge an IPV Mini?

I have a 10,000mAh external battery to charge my cell phone (Note 4, with a 3500mAh battery), which has 2 options for charging: 1.5v=1A and 2.5v=2.1A.

Is it recommended? Is it safe? Are there any precautions I need to take if I use the battery pack?

I haven't gotten around to getting an extra 18650 battery (and charger) for the IPV Mini. I've finally realized that it takes maybe 2-3 hours to charge the battery via the USB cable. But the one battery doesn't quite last me all day, depending on how heavy I'm using the Mini.

I usually carry a Volcano Inferno once the Mini dies, but the Volcano really sucks in comparison to the Mini. I'd love to be able to charge the Mini while I'm out and about.

I've added a pic of the external battery for specific information.


Thanks for all your help.  

Hi guys. Can I use my INR 18650 Samsung 20A battery with a .5 coil and try out 50 watts? I have a new mod.I have looked through the titles and searched all day but don't exactly know what I need in terms of battery. I don't even know how to use the calculators properly. Can someone direct me to some info which would help me. Thanks  

Hey guyz,i am planning to buy a mtl setup and was wondering how to decide on good battery as i cant get a good explanation to the terms being used.i plan to vape around 15-25 watt and am looking for a 18650 battery that can last me well.i also saw people saying that sometimes its better to go for more amps than mah.So i was hoping someone can help me understamd as well as decide in some batteries  

So I'm in the market for some high drain 18650 batteries and I was about to go with the Samsung 25R but then I stumbled apon the AWT IMR18650 2600mAh battery. I'm see in some places that this battery have a maximum continuous discharge of 35A and a max discharge of 40. Is this really true? Because I'm also seeing in some other places that it has a maximum continuous discharge of 20A and maximum discharge of 40A (which seems to be a bit more believable to me). If anyone has a link to some testing done on these it would be greatly appreciated. Thanks!

Here's a link to FastTech's listing where I originally found out of this battery: https://www.fasttech.com/products/2287804

And a Ebay listing saying it has a Max. Continuous of 35A: 2 PC AWT IMR 18650 Li MN Battery High Drain Rechargeable 3 7V 2600mAh 40A Yel | eBay  

I ordered a SXmini SL class with the sx485j chip and it recommends a 35a battery. I only use .15ohm coils at 60 watts so I should be good with a samsung 18650-35E right? Going to buy 21700 batteries once these start losing their charge because I just got them recently..  

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.  

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?  

I just bought 2 18650 Batteries today. I realized that on one of them, there is a small scratch. Is it still safe to use?
