ExpertPower 2 Pack High Capacity Smart Replacement Batteries (15.2V 5870mAh) for dji Phantom 4 Series Drones | dji Phantom 4, Phantom 4 Pro, Phantom 4 Pro V2.0, Phantom 4 Advanced

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.

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.

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

Batteries came promptly and they worked fine.
