18650 4000mha

Is this for real? Way cheaper than all other e-cig related sites I've seen and a lot more capacity! Anyone suspicious? 2PCS UltraFire Rechargeable 3.7V 4000mAh 18650 Li-ion Batter...

Ah okay. A little google search has answered my question--avoid!

I don't believe that Ah claim, either.

I have purchased Li-ion rechargeable batteries from DX before. Delivery from China is less than two weeks. I ordered Trustfire 14500's for a DIY hand-held laser last spring. Here is their offer on 18650 "2500 mAh". DX is a good outfit.

4,000 mah would be like a week's worth of charge, eh?

I'll modify my endorsement of DX. It's a good outfit if you do your homework and order good products. DX also sells a lot of junk along with a lot of good stuff.

Ya, and I have some 600mAh 10440 bats (says so right on the battery)
Anymore there are knockoffs of the knockoffs coming out of China, and they are all so honest

Do not use unprotected batteries in ecig mods

DX buying B rated batteries from manufactures and thats why they sell them pretty cheap (these batteries didn't pass good rating )when it comes to battery that may risk your face, hand or life if it explodes just cause I wanted to save a few bucks I rather vape less hours and charge two different batts from a good supplier .
The 1600 mah on my provaris giving me at least 8 hours of use and I used them all day, for the life of me I don't understand why you'll need 4000mah.

Unless the Mod like the provari has it's own protection.

The TrustFire Blue LI-ions I have purchased from DX work perfectly and are up to spec. I check them with a DMM from time to time out of curiosity. None have blown up yet. Do you have any documentation to support your claim that TrustFire Li-ions from DX are manufacturer's seconds and do not meet specs?

In my honest opinion Trustfire, Ultrafire, and most all of those Cheap Batts are just that, Cheap, and most of them are junk. If your gonna be putting a Mod up to your face everyday you should invest in a good safe chemistry Batt that these companies offer, Like = AW, Redilast, MNKE, these are the only 3 I will buy and I think MNKE may have stopped making there IMR Batts or the company sold ( not positive on this ) but that still leaves AW and all they offer as well as Redilast and these two companies make superior Batts over anything DX has to offer by far. Forget about price go quality all the way I say ! just my own personal opinion.

Google it and you will see why DX sell so cheap. I am not talking about trust fire or any specific battery brand, I am talking about DX .
I am happy to hear that they work for you and for what it's worth no bettery is 100% safe, we as users needs to pay attention to it and make sure we use battery safely, use the correct charger etc but, if I suspect that a supplier is buying B rated batt to sell I will stay away. Again, it may work great but it may be an accident waiting to happen and that is a chance I'm not willing to take, especially not for $3-$5 discount. I really don't mind paying $12 per battery if I trust the supplier.
That only me and my opinion .

I appreciate the opinions.

I suspect the DX prices are low because they are drop shipping right out of China. No middlemen on the other side of the Pacific rim. The free shipping is another bonus. I don't think that their paid shipping would be any faster, but I haven't tried it.
