Official DJI Phantom 4 High Capacity 5870mAh battery. This has very little use on it. I no longer have a Phantom 4 and forgot I had this in my tool box. Guaranteed to work perfect. Was going to hold on to it but not sure when I will buy another Drone. Sorry but no was y to check cycles. As I said very little use. Has a few scuffs from sitting in tool box.
