I had a problem with these batteries. They would only charge up to 91 and 93 percent. Then when I installed one of them into my Yi camera it would drop down to 85% (only one battery did this).But after notifying the seller/company, they shipped out a replacement. The replacement batteries both charged to 98 and 99 percent and are holding a charge for about 2 hours with no problems.Even though the first set of batteries were defective I'm still giving this 5 stars because of the way this seller had this resolved in less than a week. I've been using the batteries everyday and am having no problems at all. Highly recommend....

This was a GREAT deal for my Yi Action Camera! The batteries go quick when you are shooting in 4K, so you will NEED extras. The charger works great, but wish it had an AC option. Knew it was USB going in & so far has not been a problem for me. I like knowing the camera is always ready to go as I live in an area where I can get some great wildlife shots, IF I am ready. If you are buying a Yi Action camera you need this.

I don't like to charge batteries in the camera and you need more than one battery for serious use so this was the perfect deal at a low price you get a nice charger and two more decent batteries. It takes a few cycles for the batteries to get up to full speed but they are fine. With most cars now having USB ports you don't need a special car charger.

For $15 you get two batteries a charger for 3x and a micro usb cable, what a deal! I actually prefer these batteries over the standard Yi battery because of the tab location being on the side unlike the stock battery tab in the middle, it makes it far easier to remove them. Below are my test results, the batteries where fully charged then I let the camera record until it died. Results are pretty much the same and within the margin of error.

I actually had an issue with this charger at first. It would only charge batteries to 94-96% and would never fully charge. The company reached out to me and they shipped out a new charger which resolved my issue. The batteries seem to hold a charge really well as I use them across the week. So the last battery I put in has been sitting for about 4 days and still has full juice. I am recording on the Yi at 2.7/60FPS and have really good battery time, I don't do 4k so I could not comment on that.

Affordable batteries to keep your video projects going all day * Small footprint docking station that fits easily into the YI caring case * Each battery is 1400mAh which is the same size that comes with your YI camera * Package comes with two batteries, one docking station and a generous length charging cable

Update: Newmowa reached out and provided me with a replacement for the defective battery. Original: Charger worked fine and both batteries worked for a couple of cycles. One battery no longer holds the charge and sometimes the indicator light on the charger wont turn on for this battery. I tried moving the battery to different slots. I tried only charging one, two and three but it wont work.

Just got a Yi Action Camera with selfie stick. Although it came with a battery, I am usually off the grid for weeks at a time. The extra batteries will come in handy. Plus, there are three slots for batteries to recharge, so I can charge the 2 that came with this package and the one that came with Yi at the same time. I notice that it charges faster than charging the camera's battery alone. Highly recommend buying this when getting your next action camera.

Recently bought one of the Yi Lite Action cameras and when I did, this set of batteries & charging station popped up as a suggested addition to my order - so I purchased one. As I've only had this unit and batteries for a short period of time I can only comment on what my experiences have been so far. And so far they have been good. The charger seems to work as it should and as well as the two batteries. I had to charge the two batteries right out of the box, but I wanted to do that anyway to see how the charger worked. One thing I would mention about the charger - you don't get a power transformer with it (just the charging cable). Reading the instructions, I saw that the unit requires a charger with a 2.1 Amp rating. Most of the ones I had on hand were either 1.0 Amps or a bit higher. I did have one that was 2.1 Amps and used that. My guess is, you could get away with using one of the 1.0/1.5 Amp units, if you're only going to be charging a single or two batteries at the same time. If you're planning on three at a time - the higher powered charger would probably work better. Basically, lower power usually means that it's going to take longer to charge a battery. Charging the two right out of the box took around 1 hour. Another thing about the charger - it's tiny. I don't think I've ever seen one this small. Still, the batteries themselves are pretty small - so it makes sense that the charger would be too. Right now I'm happy with my purchase. I will update my review later if there are any problems with either the batteries or the charger in the future.

This was a GREAT deal for my Yi Action Camera! The batteries go quick when you are shooting in 4K, so you will NEED extras. Lovely charger, but batteries last for around 1hr 40 mins, not 2hrs
