2 – Pack Phantom 4 Batteries for Phantom 4 Series Drones, 15.2V 5870mAh High Capacity Intelligent Flight Replacement Battery for DJI Phantom4 RTK,Phantom 4 Pro, Phantom 4 Pro V2.0, Phantom 4 Advanced

I have only flew each battery once. I did watch the voltage and temperatures and they both seamed within specs of Oem original batteries. Got 21 minutes out of the first battery during mixed flying. Got around 17 minutes mostly in sport mode flying on the second. Batteries seem pretty well made and fit well. I definitely can tell the battery lights look a bit different from Oem but no biggie there. Will keep you posted as I don’t want any explosion or crash as I would like to keep my 7 year old drone in good shape. Still looks and flys like the day I bought it. To be continued 4 battery cycles later. Have put them in regular battery rotation as they fly like oem batteries. No issues or problems found. Very happy I purchased.

I received two batteries, one of which came as new and works perfectly, the second battery is dirty and battered, I imagine it was already used

My drone wouldn't work because the batteries were old sitting on a shelf for too long and the cells became uneven. Now with these batteries my drone is up and flying again

I was hesitant in buying these batteries and I regret it. These cheap knock offs are not DJI approved. I had three incidents where I went from 60% charge flying to 5% critically low the first two times I was able to get it down close enough to the ground to land roughly. One time it landed in the grass across from my house, broke the blades, but still worked the second time it landed on my roof slid off the top of my roof, and I caught it before it hit the ground the third time I could not possibly get it down fast enough in at 150 feet it crashed and now I have no DJI phantom four pro it's a mess not repairable not fixable

good product for price fast shipping

Both batteries I oRdered works but don't fit as tight as originals. Battery ejected after slight crash landing. Everything still worked.

After charging the batteries over night. We took the drone out for a fly. Both batteries last about 30 minutes. I think we will buy more.

Update: Sooo, my first post about this battery was not good. However, since that time I have found the battery DOES actually work. The battery does not fit into the drone the same way as the OEM battery. Usually you just slap it into the back of the drone, and it snapped into place. I did not notice the problem until the third time I tried to use it which is outside of the 30 day return window so I thought this was going to be a negative experience. The first couple of times I flew with no real problems. I did notice one time they gave me an error but I took the battery out and pushed it in a little harder and then was able to fly. But today, no go! I took the battery in and out seven times and I’m still getting an error code and it says the battery not installed properly. UPDATE: I slept on it overnight and then found out after I was messing with it again, that if I push the latches on the top or bottom of the battery at the same time and inserted fully into the back of the drone, and THEN release the latches, it sits in place just fine. No need to slap it into the back of the drone to get the latches to catch. Once it gets to the point where the latches would need to engage, squeeze them together push a little further into the drone and it fits perfectly. I used both batteries today with no problems whatsoever.
