2-Pack AZ16-1 Replacement Battery and LCD Dual USB Charger for XiaoYi 4K and YI Lite Sport Cameras

These did not fit into my camera as I was hoping they would. I returned them, but for the correct application, I'm sure they would have been great!

Work properly and fix my problem. Because I haven’t the original charger for my sport camera.

After seeing a log of weak reviews on other brands and mixed on this one, it appeared to be worth a shot. At least initially I couldn’t be more pleased. Batteries last about as long as my original Yi Lite camera battery and the charger is very nice and gives clear indications of charge levels. Have worked great after a few uses. I just hope they hold up.

Bought these to use in a Yi 4k I've had for I don't know how long. Original battery is in excess of 5 years old and has been put through a few hundred charge cycles. Also have Smatree batteries but lost one and only have one spare so I picked these up.I charged all batteries using this charger and all were tested between 10 minutes and 2hrs after charging. did a max load run down test, 4k ultra at 24fps, set the camera on my desk and hit record and timed them until they died. I let the camera cool for 15-20 minutes between each run and all were at 71-75F.Test order went: Smatree, Yi original, Powertrust 1, PowerTrust 2Results:Yi orig: 1hr 59minsSmatree: 1hr 39minsPowerTrust: 1hr: 15minsPowerTrust: 1hr 09minsSo safe to say I'm very disappointed. The 5+ year old well used original battery lasts 50% longer then the average of the two new Powertrust batteries. Unfortunately you can't get the originals and if you need spares you need spares, and they are all varying levels of junk, just putting my results here so people know what they are getting.I only ran one test for each battery so didn't account for any variation but I would expect maybe 5-10 minutes of variation at best, and seeing as both PowerTrust batteries performed within 5-10 minutes I think it's safe to say the test is accurate enough without repeating it.I've got all my batteries marked with how long they last and numbered 1-4 from best to worst so on long days I can coordinate my use case and make sure I have the best battery in for the longest sections for recording.

Nice thanks

Charged my batteries with no problems. Great led readout on charging progress.

they hold and last fine for the video camera i use these for .
