FlyHi Phantom 4 Series 2-Pack 15.2V 5870mAh Intelligent Flight LiPo Replacement Battery + Battery Safe Bag for DJI Phantom 4, Phantom 4 Pro, Phantom 4 Pro Plus, Phantom 4 Advanced, Phantom 4 Pro V2.0

I collect a lot if images for GIS mapping. so I go through a lot of batteries. I currently operate 2 Phantom 4's and keep around 12 batteries in stock. I have found these to be great replacement and get better performance e than the original ones. Great produce and good price.Update: I was so satisfied with the first batteries, I just purchased a second set. Very happy.Update 10-16-19 Putting these batteries though the ringer and impressed by their durability. I will confirm that they do last longer than the standard DJI batteries. Several times my software indicated that two batteries would be necessary and completed the job with just one of these new batteries. Glad that I picked these batteries.

Received the order for 2-pack of 15.2V 5870mAh batteries on July 22, 2019 as expected. After a full charge, each battery was tested in my Phantom 4 UAV. One battery operated correctly but one did not. FlyHi was contacted about the issue and promptly sent a replacement delivered on July 29, 2019. The replacement battery tested as good in my UAV today. I appreciate the attention and prompt response by FlyHi.

These seem to be electronically perfect batteries, but the fit in the drone is not quite right. I had a heck of a time getting the battery out of the drone. Seems like the release button doesn’t quite push the latch down far enough, so it was practically stuck in the drone. I guesse that’s better than it falling out!

Aside from being a little snug fitting, these batteries are performing like DJI original batteries do.

These batteries worked great the first time, however I received several “bad battery placement” warnings on my DJI app the other day. I have since retested them and they seem to work fine now. I even updated the drone on one. The cold weather may have been a factor 28 degrees Fahrenheit in Ohio.They don’t seem to make a perfect fit every time but when they do they work really well, and you get 2 for the price of one DJI battery.

Fit very snug. good flight time, but DEAD on DJI dock in storage mode.Updated : contacted the seller/manufacture because still within 1 yr warranty. They are nice enough to send me a replacement battery.

Used for several cycles now and they work fine. Averaging about 23 minutes flight with 15% safe return.

I use these in my phantom 4 pro and I have yet to run out of battery before completing the project I’m doing at the time.
