If it is free shipping, then yes, it is an oversight.
I’m weary about ordering cells at banggood.com The first result is MECO 4 x 4000Mah 18650s for $9.99 with a 4.84/5 rating by 635 users. The price and mah reading have to be too good to be true.
Here’s a review: “Data was provided by professional liars (not professional tools). Weighing just 20 grams (see the reviews), their real (discharge) capacity cannot reach 2000 mAh, as the victims of this scam report everywhere.
Who are we to trust on this site?
BG sells some impossible cells, so how can we trust them with the rest? I don’t.
I have faith in the BLFers that say BG sells real 30Qs.
Please somebody tell me that BG sells real 30Qs.
Banggood sells real 30Qs.
There are many things better than you may believe. Finding stuff which doesn't makes justice to that does not make them impossible.
The problem here is that MECO is a swindler brand. That's about it. Don't buy it and spread the word if you feel like that.

General rule of thumb is to buy name brand cells and if forum members here say they are legit, then that is very much true. Issue here is BG sells fraudulent cells along with real cells, where as sellers like liionwholesale do not.
Banggood sells abroad worldwide, product judgment free. Judgment free like the subconscious mind. If you don't like something from their catalog just don't buy it. There's people who buys those “bad” products because they know no better, and they hold responsible from the way they believe and the lessons which to them that entails. So, of course, there is reason.
After seeing this I just went and tried and my order went through. We’ll see if they actually ship them…
That being said, I ordered 2x 26650 from FT a couple months back, the order went through and they shipped, but now, none will.
Oh…and while I am here. Anyone have a place that will deliver the Shockli 26650 to Canada?
Shockli has an aliexpress store, did you try there?
I did. They won’t ship here even though a lot of others will…
Or like this
My order has been shipped.
Wow, that’s surprising. I’m tempted to order some more cells that I don’t really need right now.
You can’t. That lasted just one day but who knows, it may happen again.
Yeah, the cells are probably going to get blocked at customs.
I received a cell order from BG in May 2018. There is hope.
Please keep in mind there are only a few actual manufacturers of lithium batteries. I have used high drain IMR/INR batteries for vaping for the better part of a decade. If a cell is not sold as Sony, Sanyo, Panasonic, LG… It was most likely made by one of them and did not pass QC and sold off to be re-wrapped with usually grossly exaggerated specs. How would you like to buy a car with exaggerated specs? Would you feel safe if you knew the car didn’t pass the manufacturers QC?
As a vaper you should know these battery manufacturers are trying to distance themselves from vaping. Probably due to liability. In any case you shouldn’t be surprised that cells will be sold under all sorts of names since they do not intend to sell directly to consumers. What you said may exist but it’s far from the truth if you are shopping at the sites we mention. Look at the batteries Eneloop makes without their name on it…
I’ve got plenty of cells from Banggood in the past, and they do seem genuine and test that way too. But, yeah, you could be right that they are not grade A or B cells, and failed inspection for some reason not related to performance.
I’ve bought from Illumn more recently, hoping to get a better guarantee of good quality cells. But, since the manufacturers don’t sell to consumers, I suppose there’s no guarantee of quality from US retailers either.
As consumers, we’re stuck taking the risk ourselves.
