Efest Luc V4 Charging

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 have a variable voltage/wattage battery and I have heard that some say charge it as often as you can this reduces stress, others say that's bad, some say a combination of long and short cycles but I don't know which is best. My battery's manual said get down to 10% but it doesn't measure it accurately (but I love these batteries so I don't want to change but they are expensive so I want to prolong their life span as long as possible even if that does mean charging them very often.) I do have two so charging often isn't an inconvenience for me if that's what I am supposed to do.  

So i got a smok gpriv deluxe edition about 3 months ago. Its worked perfectly but then i let it sit unused for around 1 month. Now when trying to charge the batteries nothing works. Its not showing any signs of life. Im currently charging one battery in a smok grip but its still on 0 percent after 20 minutes of charging. Is it a battery issue? Or a mod issue  

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?  

Hey everybody. Love this forum. I've got a question. I've got an MVP2, MVP3 and iStick 50. Long question short, do you think it's better for the life of these batteries (since I can't replace them) to run them all the way down, THEN charge them or just charge them every night until I wake up regardless of the life in them unless they are full? And, how long would any of you estimate these mods will last until they completely die? I mean using them every day. Chain vaping. 6 months? A year? I ask because I really thought about getting a Sigelei and it's too late now, but I would like to now for future reference.  

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  

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
I just got a Xtar VC2s charger for my 21700 batteries (Samsung 40T).
Chose that charger also because it "charges at safe low current".

When it charges 2 batteries, it's at about 1000 mAh for each battery. All good.
But when charging only one battery, it charges it at 2000 mAh. Hmm?

I assume 2000 mAh is still "safe".. But won't that reduce lifespan on the battery?

The charger manual says "when the power supply is insufficient, the charger will reduce the charge current correspondingly".
So maybe I should get a usb power supply with like 1000 mAh output?

I will only be charging one battery at a time, and prefer charging slowly if that gives more safety and lifespan.

But I don't know if charging at 2000 mAh is really an issue..  

Hi

I'm using Samsung 21700 T40 batteries.
Trying to figure out..
Is it best to charge a battery when it's discharged or nearly discharged?

I like to keep things simple with a routine of charging once a day, but then the battery will be set to charge even when there's 15-30% power left.

Is that bad for the battery?  

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.
