Cheap, works great, and charges great. More powerful than my 18650's for sure. Holds charge much longer too. Vapesourcing was great to purchase from too.

I was sceptical about the battery because of how low the price is but have been pleasantly surprised at how well the have been performing. They are the best I could find for the price and shipping was quick. I ran them down until they were completely dead when I charged them they charged a little over 3800mah I'm pretty sure they are not 40amp but they have not over heated or got warm vaping at .15 ohm 120 watts.

Q Why you can't ship to Canada, we are not banning anything. We are all legal here to vape a d I needed 21700 batteries . Just like 3 or 4

A Hello, as the battery is special, it needs special delivery channels while we don't have to ship to Canada. But you can buy some other vape product, then we can take them together to ship to you.
