Being a relatively new drone flyer, and having just created my first account on Healthydrones.com, I have discovered that both of my P4 drone batteries have been typically running at an average of 128f over a period of about 30 flights. This seems to be a bit on the hot side. I am wondering what the safe temperature range is for the P4 batteries? Having read all the horror stories about these batteries catching on fire, I do not want to sacrifice a $1400 drone because of my ignorance. Also, in the DJI Go app, there is a time to discharge in the advanced battery settings that can range from 1 to 10 days. I am wondering what this is for, and what are the recommended settings?
