Hi all, I'm a newbie to the forum. Looking for help with my P4P2+. I have 4 batteries, all of which have been used fine. Recently, with no abuse, 2 will not seat in the drone, When installed, there is a slight gap on the left side. The two working batteries do not have this gap. I inspected the alignment rails on both the drone and battery finding nothing apparently wrong. No issues with the two "working" batteries. Any suggestions? Batteries are expensive and I'd rather not nave to purchase new ones. All batteries were purchased new from Amazon. Thanks!
