I got these last weekend on my P3a and they would not let me take off at all, even though it was sunny and in the low 60s. I realized that I had the drone and batteries in the car overnight and it got down in the 30s. So even if the ambient temp is in the 60s, if you leave your batteries in a cold environment, they will be cold when you take them out to fly and you will get a warning.
Open the case and let them warm up to room temp before you fly, or put them on the dash if you drive out to your fly site. They should not be cold to the touch. There are enough cold battery drop write ups on this forum that if you ignore the battery too cold warnings and are below 50%, your taking your chances....fly somewhere where you can pick up the drone should if force a landing out of the blue...been there....
