I purchased a used P3S. Came with lots of accessories including ArgTek and 3 batteries. I use Litchi. I flew it and learned about it for 3 or 4 days. Max range I flew to, without signal loss, was 3200 feet. I ordered 2 more batteries. When they came in, I charged them up and put them in the case. I went out a fly a waypoint mission. It flew the mission(15 Minutes). I landed and because the battery was at 45%, put a charged battery in it. Tried to fly it to do some still photos. It flew out to about 200 feet, 160’ alt, and lost signal and RTH. It wouldn’t let me cancel RTH and Land until it was about 50’ over Home. I have tried every battery, same result. Deleted Litchi and reinstalled, same. Opened DJI Go and flew. It went to 1800 ft and RTH. Everything I can see in settings says normal or latest version. If there is already a thread about this, could someone tell me. I don’t want to irritate anyone with something that’s been addressed 100 times, just not sure what to look for. Thanks in advance.
