Just booted up my breadboard rig to check something and was getting the flashing lightning bolt? My new Pi 3B+ is in this rig. I was using my 5V 10A power pack too. Very recent fresh install of the latest Raspbian updated and upgraded? Updated and upgraded again and it went away? I measured just under 4.9V at my breadboard. There was an issue with false low volt warnings with the 3B+ but I could have sworn my last update upgrade patched it and fixed it? Anyway, just a heads up if you own a 3B+ and get the warning. Do a sudo apt-get update sudo apt-get upgrade. Maybe even run them both twice, update, upgrade, update, upgrade until its says 0 upgraded.
