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.  

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!  

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?  

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
I'm usually vaping at just 14 watt (mouth to lung, nothing heavy).

Now I'm soon getting a new mod that takes 21700 batteries, so I'm searching for the best batteries without spending too much or too little.
(aiming for Samsung, LG or Sony, to be safe)

I see some batteries hold 5000 mah, like the Samsung 50E (cyan).
But it only has about 10 amp discharge rate.
So less than half than "regular" 4000 mah batteries for example.

Is 10 amp more than enough for vaping at just 14 watts, or should I find a more "high-drain" battery?
I want to be safe and avoid risks or heat.  

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  

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 wanna buy the sigelei oni edition 150watt but iv not used any box mods that require batteries yet, my jellyfish and innovkin has internal batteries, can you gents recommend 2 good batts and charger. and is there any tips i might need to know.  

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!  

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.
