Hello! So I heard that if you hold the battery power button for 5 second, it will show you battery health. Is that right? And I have 2 batteries and both showed all 4 green lights. Does it mean that they are 100% healthy?
It shows so-called battery life which is determined by the number of full charge-discharge cycles the battery has had to date. Four solid lamps would be 90%-100% life left.
Hello and good day Filip Kyzek. Thank you for raising this inquiry today. Mark The Droner is correct if you have four solid light in your DJI Phantom 4 Pro Intelligent Flight Battery it means that the battery has 90% to 100 % battery life. For additional information I will be posting a link for you to be able to check the DJI Intelligent Flight Battery Safety Guidelines Manual. Thank you for your support.
