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
Efest IMR 18650 LiMn 2800mAh Battery - Flat Top - 35 Amp
They claim to be 35a continuous & 80 pulse. . .
Has anyone tried these?
if they really live up to the specs these will be the best batteries on the market now since no other battery can claim a 35a continuous rating. Not to mention 2800mah? Dang. Just note these are not the same batteries from before. The previous ones had a 35 amp pulse rating
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
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!
Hey guys if i was to use the cloupor mini 30 watt regulated device with an efest imr 18650 35a
battery am i safe? will the cloupor see any overheating of the battery if it were to happen? or will it see if the ohms are too low? the lowest ohms i plan on using is .8 possibly .6 but i just wanted to know how safe is this device? also i am aware of the recall on this i will be doing the "too hot" test on it. thanks for your replys!
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?
I got a problem with my Luxotic Surface. I'm using a LG Choco Battery 18650, it was fully charged and when I press the fire button suddenly it appears for Battery Low even the battery was on fully charged. I tried my spare battery maybe its just a mistake putting a fully charge battery, but it was the same issue also with the spare battery. I tried the 2 batteries with my Geek Vape Aegis 100W to check whether my batteries are already broke but it works fine. I was vaping for my Luxotic Surface by 55.0 Wattage, 0.21 ohms, 3.40 Voltage. Can someone help me out to fix this problem?
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.
I have the ipv4 on pre order (can't wait) im stuck on the battery choice. I want to find the best choice for a vv/ww mod. With the most mahmp life and amp draw load. I was thinking about the LG HE4 . 2500MAH 35A High drain. I heard the efest purple has great battery life. But I enjoy lower builds. .15-.2 occasional .1 . I just want the safest battery with the most load and lifespan. Anyone with some info plz enlighten me. We gotta stay safe. Thxx
Will I get longer battery life if I charge my batteries at .5 amps vs. 2 amps? I feel like I'm getting less battery life by charging them so quickly. Any info would be appreciated, thanks!
