You guys are something else here. You really all are. This man just bought batteries from a reputable Chinese Vendor, and of a battery type that at this point has seen so few counterfeits, and you are all instantly jumping to the conclusion of them being fake. You didnt even know the type of battery before you all jumped on him with the whole "Its from china, its .... mentality."
Taking from personal experience, I have purchased EVERY SINGLE ONE of my batteries from China, and guess what? They're all authentic. All 30 of them. They all work as they should, they all weigh as they should. I can push them up to 20 amps in my regulated mods and they are still ice cold, and working well.
Don't start bashing things without knowing the whole deal, or without ever having dealt with Chinese vendors. As long as you are ordering from one of the Reputable vendors(3F, Focal, FT, GB, HG) the chance of getting a counterfeit product is incredibly low. Also, newsflash, your local B&M, probably gets their supply from one of these vendors for batteries. Just saying.
Ive bought thousands of dollars worth of gear from China.
I would not risk buying cells from the country responsible for all counterfeit batteries.
There is zero recourse.
Just to save $2.
Illumination supply actually tests their cells. They have a stellar reputation and have been servicing high end flashlight owners longer than there has been a vape scene.
They have an actual brick and mortar store in California.
No question they are as legit as it comes.
So......
Why risk it?
To save $2?
My peace of mind is worth more than that.
Vape safe. Know your gear.
