21700 battery chargers

There are slight variations in every single cell. Some of them don't perform as good as they should, so they're rated lower(B or C) and sold cheaper than their A graded cousins.

However, considering that Samsung, Sanyo/Panasonic, Sony and LG have very high quality standards, lower grade cells from these manufacturers still outperform most "china-cells".

Hmm... Efest buys substandard Sony and Panasonic batteries and one blew up in a Florida man's mouth.

The batteries originated with a Chinese company named E-fest, which purchases lower-grade batteries from companies such as Sony and Panasonic, Morgan said. R-L Sales, which is based in Utah, imports them from China and sells them online, he added.

Aw come on. That stupid ...... gave himself a facial correction with the help of a mech mod. There are hundreds of possibilities why he blew up, and the same might have happened with brand new A-grade cells. But if you want money, it's always better to blame someone else for your idiocy of course.

That said, it's still prefereable to buy A-grade cells from the Big4 for that extra bit or safety and performance, but that still doesn't make their lower grades bad, especially in comparison to a lot of the other crap you can purchase out there, like noname cells from S**tfire, AWT, and a whole bunch of other rewrapping companies.

Aw come on! Efest sells substandard cells and everyone knows it. No sense in defending them. That's a losing game. And Efest is very commonly sold at vape shops is a huge crime IMHO. Vapers should be using grade A cells and nothing less.

We have, I think, to differ between reasons for Rewrapping of genuine cells. In Europe, for Example, we have directive 2006/66/EC. In this directive the European Union (item 21) instruct how a battery should be shown-up on the market.
I heard, that in France and Italy off-line shops are not allowed to sell anymore genuine batteries as they are.
Another reason whould be IMO to allow yourself as a company to switch between bare cells behind the shrink, in order to be flexible. Those companies must be punished by the customers hard as soon as they would be caught with such a behaviour.

I tend to buy lithium cells from vendors who specialize in battery sales. RTDVapor, IMRBatteries, Battery Bro, etc. The prices are generally cheaper than vape shops and the quality is guaranteed to be OEM. So far, the cells I get from them tend to have internal resistance numbers in the 20 something ohm range.

The last thing I want is for a cell to go into runaway meltdown while I'm holding it in a mod. So far, so good. Internal resistance values indicate condition and longevity of a cell. The Zanflare C4 charger provides resistance reading and right now it's my favorite charger.

I always stick with Illumn.
Personally, I would never buy batteries from a vape shop.

Standards are subjective, because objectively speaking there just isn't anything like that. All manufacturers just guess. Including the Big4.

But that doesn't matter here. And neither am I defending Efest.
If you have the option to get genuine grade A cells, you should always go for those.
But not everyone has that option and there are a lot worse options than grade B or even C cells from the Big4 out there.

Greetings,
I've been using 18650s for the last few years and I have been charging them with efest LUC chargers, the LUC 6 most recently.
I'm getting ready to invest in some 21700s and I'm just curious which chargers people prefer for these batteries. Also curious if anyone has any experience using LUC chargers with 21700s.
Thanks

Well, I ended up going with the GYRFALCON All-88 and some 30Ts.
Extremely happy with my purchase. Thanks everyone for your input.

What are you considering?

What are you considering?

What I would like is an 8 bay that has a simple screen. Needs to accept 21700 & 18650, preferably in all bays. Choice of .5-2 amp charge. Some I have looked at the menu seems a pita for us simple minded folk. Love my luc 6 due to the simplicity of the screen.

I'm leaning toward the Gyrfalcon AL-44.

Yeah, I've been need using the Luc 6 for quite some time now. I love it too.
The fact that this one only charges up to one amp was not a deal-breaker for me because I try to charge as low as I can, within time constraints.
This is a very simple charger, however. I haven't read the manual and I had it figured out in about 30 seconds.
The only thing I don't really like about it is that the screen goes dormant after a while and you have to tap a button to bring it up. I like to be able to just walk by the charger and check the batts.

The only reason I went with the 88 is that I vape at fairly high wattages and go through a fair amount of batteries and with the added charge time of 21700s compared to 18650s I wanted to have some backup batteries.

I read when it goes darK if you hold the button for a few seconds the screen will stay on for you. Thank you for the reply.

I vape low, and I'm only going to be using a 21700 in one mod, so I think this will be enough for me. If not, I always have my trusty XTAR VP2 to fall back on for 18650s.

UPDATE: Ended up ordering the 88, after all, 'cause the 44 was out of stock and I am an impatient brat. Besides, at the rate I'm going, I'll need eight bays soon enough anyway.
