ExpertPower 2 Pack High Capacity (15.2V 5870mAh) Intelligent Flight Replacement Battery for DJI Phantom 4 Series Drones| DJI Phantom 4, Phantom 4 Pro, Phantom 4 Pro V2.0, Phantom 4 Advanced

No reservations about ordering from this company again. Great product great customer service.

These batteries had a great value for two and looked very promising. I bought them at the end of March and put about 3 charge cycles on each of them in a week's time. The drone flew well and I became brave enough to go a little higher and a bit further, putting a lot of trust in these aftermarket batteries. Around the 5th cycle in I found the courage to take it up to about 450 ft and run it out about half a mile. Easy. No worries in my mind after that flight.After the 6th charge cycle, I took the drone up to watch a nighttime, lightning storm way off in the distance. It was beautiful. I had it sitting at 500 ft recording the most amazing storm and well-lit moon for about 5 minutes. Just as I was about to bring it down I heard the motors stop. It took me a second to realize it was in a free fall. I looked at my screen to see a disconnection message and backed up a few feet because it was falling fast and I had no idea where it was. As it got to about 100 ft the drone tried to come back on and I heard the motor sounds for a split second before it hit a powerline and then the road. I could see only white plastic exploding from the crash point outward into the yard. Thank goodness I live far away from others or the crash could've been devastating.I'm out of a drone and still paying for these batteries, but I'm thankful no one got hurt. I do implore other unmanned aircraft pilots to STAY AWAY from these batteries. Your drone will thank you for spending the extra cash on the OEM batteries.

I have the original Phantom 4, with the original 5350 mAh battery. In less than 20 recharges, it's occasionally throwing a bad cell error, so I decided to these two new aftermarket batteries, which offer the increased 5870 mAh capacity of the newer models.I am very happy to report that both batteries worked perfectly out of the box. They were delivered with half charge as expected and charged right up. They function identically to the OEM battery, and while not identical in design, seem to be built to a very similar level of qualty, including the electrical connection.I'm happy to report that I am getting slightly increased flight times as well, I'm easily able to fly for 25 minutes with power remaining, pretty much no matter how I'm flying! Time well tell how many recharge cycles I can get in total, but so far, several cycles later they are performing identically.Considering the cost of the OEM improved 5870 mAh batteries, this is quite the value.

Batteries came promptly and they worked fine.

These work just fine. I have a 3 battery charger that the DzjI batteries fit into nicely. These don't fit the 3 batt charger but do charge as a single battery with the DJI charger. The button seems be poorly placed. But, it works fine.

I just received the batteries after having returned my "Powerextra" batteries because they were poorly made. The connectors bent on them like tin foil and the venting ports on the side of the battery were not fully open. The construction seems much better on these expertpower batteries and I am happy so far.

I have a Phantom 4 V2. At first, everything seemed fine. They charged up and I had to update them once in the drone. I did a brief test flight with both and everything seemed to work. When I actually put them to work in a project I was doing, they performed fine the first time but when I took them out each of them flashed a single LED on the opposite side of where it normally would. Then neither would take a charge. The BIGGER issue is that after using these batteries, it infected my regular DJI batteries. The DJI batteries operated just fine prior to me using the EP batteries. After letting the DJI batteries sit for a couple of hours, they still flashed incorrectly but at least they charged. They operated regularly after that. The EP batteries, while one would take a charge, the other wouldn't. I kept the one EP battery that charged as a last resort but, fortunately, didn't need to use it.I was disappointed as these are half the cost and I've never had an issue with EP batteries on other equipment but for the drone it almost cost me getting the one time only footage I needed to get. There was no second chance with this event. I will pay for the DJI batteries from now on. I returned the EP batteries and ordered replacements from DJI.

I do recommend these batteries I own a DJI phantom 4 they work very well charge under 50 minutes and the batteries last about 40 minutes I highly recommend these for all you DJI phantom 4 owners
