U.S. Edition AZ13-2 Battery (2-Pack) and Dual USB Charger kit for AZ13-2 and Xiaomi YI Action Camera(Only for Official U.S. Edition)

Finally, a charger and batteries made for the US Edition Yi action camera. Batteries fit perfectly, and the charger works great. I haven't tested out the battery life yet, but I'm just happy I don't have to do any macgyering to the batteries to make them fit. It would've been nice if this came with an outlet plug, but it's easy enough for me to just switch cables out as needed since I don't recharge the batteries all the time. Overall, I'm really satisfied with this product.

I'm very happy with this kit and the batteries. They fit the US version of the Yi Action very well and provide batter life that is comparable to the battery that was included with the camera. I get about 75 minutes when recording at 1080P/60. The charger works great for charging two batteries at a time and I use it to charge both these batteries and the one that came with the camera.

Both of the batterys started to melt inside the camera. Now the camera is broken. If I left the 2nd one on the camera pretty sure it would of caused a fire. The first battery (The left one bearly melted) one made the light flicker on the go off. So I tried the 2nd one nothing. Then I smelled the burning plastic and found the problem. Do not trust this battery in your house.

Use these batterys quite a bit on my quadcopter's hd camera. They last longer than the originals. 2 thumbs up!

Work just like stock battery. Charger seems well-made, but I wish it had an AC plug instead of just USB.

They barely fit in my Xiaomi To but they do fit.

Batteries work great. It last about as long as the original battery. The charger is not very good. It's made of cheap plastic and broke after two uses. The charger splits in half when i tried to take the batteries out of the charger.

It seems this posting was created before the 4k Yi Camera was released.It states no where here that it won't be compatible with the 4K version of the Yi.All it says it to make sure its the US Edition, which the 4K Yi here on amazon IS the US edition.If I would have payed enough attention I could have figured it out cause the tab is on the back instead of top,but then again I only heard of the Yi as a 4K camera, had no idea there was a different version.
