Purple efest 18650 battery warning

Thank you for Posting This.

 

One more reason I feel safer with a mod that limits current to 3.5A (well, I do have one that does 4 amps). Tell me when I approach the limit and cut me off, don't show me with fireworks ...

 

Wow. Efest = not to be believed specs!

 

I would like to see someone else Corroborate what the person in the link says he has found before I Condemn efest.

But if it is True, this is Much Worse than some Bootlegger Re-Wrapping Batteries in my Mind.

 

Efest does seem to have a fanbase that is for sure but to possibly be labeling a 4 amp battery as a 20 amp? Wow. Just wow.

I would like to see some confirmation but I have no reason to doubt the source either. That site has been a source of accurate information for quite some time.

Personally, I don't think I can take any efest spec seriously at this point however.

 

I'm not a efest Fanboi or an efest Hater.

But I have Noticed over the Last Year of so, there seems to have been Many Reports of eFest Problems as apposed to something like an AW or a Panasonic or a Sony in the same Class.

 

Efest IS some Bootlegger Re-Wrapping Batteries

 

This is old news to me.

I've been cautioning vapers for months here on ECF that Efest (and vendor resellers) has a history of exaggerating the specs of ohms and amps on their battery spec sheets. Much like the exaggerated specs that Trustfire, Ultrafire, and Surefire do for their batteries, once independent testers bench test the batteries or unwrap the batteries to see what is beneath the skin, the advertised specs are proven to be exaggerated.

I wasn't surprised to find out that the purple Efest 2100mah 30 amp battery was a re-wrapped Sony 2100mah 30 amp battery. Nothing wrong with that, as many manufacturers re-wrap cells made by other manufacturers (ie AW and Orbtronics).

Purple Efest 30 amp battery is same cell as Sony VTC4 30 amp battery

Purple Efest 30 & 35 amp batteries?

However, when Efest labels their purple 2600mah battery as being a 35 amp battery, and then we find out that it is a LG18650HE2 battery (which LG claims has only a 20 amp continuous amp rating), then that's being disreputable and deceiving in my mind. These batteries are being marketed to vapers who sub-ohm and there's a big difference in 20 and 35 amps; especially if someone is counting on those extra 15 amps as a safety cushion.

The EH brand 18650 2500mAh advertised at 35A are also rebranded LG18650HE2 20A.

Now the above revelation that the purple Efest 3100 mah advertised to have 20 amps is found to have only 4 - 6 amps continuous is even more appalling.

 

What I don't get is efest called the Sony what it is: 2100 mAh and 30A cont max.

I wonder why they didn't exaggerate the spec on that one?

Calling a 4 amp battery 20A is over the top!

 

Here's where I'm confused.

Is it Efest that is turning out some Batteries that Aren't what they are Supposed to be? Or is this a Story about someone getting their hands on an el-Fack-O Battery?

 

I doubt that they are fake Efests being tested. This is occuring with three different models of purple Efest batteries. When researching battery specs for my blog I found that Efest was the one manufacturer who had the most discrepancies. Even the flashlight enthusiasts were finding exaggerated battery specs with their independent bench testing. It was like Efest themselves didn't know the specs.

 

Hard to know for sure Exactly what is Going On.

But it is Very Troubling at best.

 

this is really bad, I didn't trust efest much before but now this is plain wrong.

ECF should put a sticky so that everybody knows this info

 

Maybe before we do this...



... we should let this Play Out a Bit?

I'm sure that if Things are as the Tester in the Link says they are, that some Other's will Duplicate what is being Reported.

 

Can we sticky this thread to warn others?

Max. Continuous Discharge Current 3.636A

 

Maybe we ought to start linking this thread in any post where someone is wanting to know about Efest batts. That might get the word out to be cautious about buying Efest batts, especially for those wanting to sub ohm.

 

This is not "new" news... This has been discussed for months now in the forum. I have seen Baditude post his findings over a dozen times in as many threads. If it weren't for him this info would've been lost in some old post somewhere. It's great that he re-posts this info, and I think he will continue to do so. I think he is the utmost authority on batteries here in this forum. He has done some great research on batteries and keeps us all up to date on the ins and outs of them all. I have a few of the older Efest batteries and don't use them anymore. I "personally" place Efest in the same category as the manufacturers with the word "fire" in their name... They would be ok to use in a flashlight, but not an ecig!!!

 

I've been posting this information myself for the last few months. But it is not my job to be the town cryer for this board. Everyone should warn others who are using Efest or considering buying Efest batteries that what is advertised may not be what you will get.

 

Why would you post the specs for a Panasonic NCR18650BE in an Efest discussion thread? Just FYI, the "E" in is for economy, and that would be the first sign you shouldn't use it in any ecig if you are trying to vape safely...
