New Efest 35amp Continuous Discharge Batteries?

Ok, one of my 30A batteries went kaput, and now I'm left with one last Sony VTC4. It's time for me to get a new set of batteries for my dripper. I'd like to ask your opinions as to which to get...but here's some criteria.

First, Sony is ruled out. There are too many fakes out there, and even an honest vendor can get duped. Since I will use a 20A build on it, I want to make sure they're rated at what they say they are. So no Sony's, even though I know they're good batteries, I dont want to take the risk.

Second, IT has to be 30A or better CONTINUOUS. It has to be explicitly stated that it has a continuous discharge rate of 30A or higher. Pulse ratings do not count.

third, 2000 mAh or higher.


I am thinking of going with MXJO 2500 mAh 35a continuous... But I don't know their track record.

Another option is the Efest 35a 2800 mAh batteries.

Any other advice would be welcome. Sources to buy would be nice as well.

Thank you in advance.  

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  

This happened just last night. Before bed last night, I decided to check the forums and email. My wife already was asleep. I decided to load up my dripper and vape while browsing. I put in a freshly charged battery. I was running a .2 ohm build in an older Efest 1600 V1 (rewrapped sony VTC3). I took a few puffs as I tried to load the website.... the internet was down, so I locked the mod, and went to the router to check things out.... After working with the router for about 5 minutes, I realized, I wasn't getting a signal from the internet provider.... so, I sat down to do some maintenance.... Through the light of the computer monitor, I saw some vapor coming from the drip tip..... the mod was NOT locked, and it was continuously firing for 5+ minutes. I went to pick it up, and it was too hot to pickup, so I turned it on the side so it would stop firing..... I grabbed a towel, and took it into the bathroom put it in the sink and turned on the water.... It sizzled when the water hit the mod. After a few seconds, I unscrewed the bottom button and took the battery out.

The mod cooled down battery stayed in the water for a bit. It was so hot, it started to split the shrink wrapping (it continued to shrink it until it split). The mod was fine, battery was fine... no bulging, smell, etc. I still might not use the battery just in case. turned out, I had not locked the bottom ring.

So, continued advice... do not vape a pulse rating, always vape continuous rating and use safe batteries.  

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.  

Seems efest batteries are not all that bad...

Best batteries for cloud chasers/high current: Sony VTC4 vs Efest 38A – Liion Wholesale Batteries  

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!  

Taking the advice of ECF members, I'm planning on buying Samsung INR18650 25R batteries for a 30w device (as opposed to my current Panasonic that has a 6ish max amp output). My local vendor has them, but two things are strange to me.
1.) Their price is actually a little cheaper than Fasttechs, usually products there are quite more expensive
2.) They are green, while FT and a couple other places i've googled has them as blue

This is the vendor site:
Baterija Samsung INR18650 25R 2500mAh - 18650 - Li-on, Ni-Mh baterije - Baterije i punjači E cigarete | E tekućine
This is how they look pretty much everywhere else:
$9.75 Authentic Samsung INR18650-25R 3.6V 2500mAh Rechargeable Li-Ion Batteries (2-Pack) - 35A peak discharge / 22A continuous discharge at FastTech - Worldwide Free Shipping

So are the batteries from the first site fake or what's the deal with that?
 

I'm charging a purple EFEST IMR battery in an XTAR LI-ION battery charger and I wanted to make sure Efest IMR purple is actually covered under LI-ION charging.. I can upload pictures in a second but I've been charging the battery for about an hour and this is my first electrical mod so I am trying to make sure, thank you. It says it is for rechargeable Li-ion batteries only but so far the battery is not hot or any problems  

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...  

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?
