I have had my Anafi for nearly four years. Two of the batteries will fly for about 5 minutes, one 30 seconds, so all more or less finished. I have just bought a new Anafi battery from Parrot. I have read various threads about batteries, but I want to make sure I am looking after the new battery as well as I can. In the past the batteries just discharged themselves meaning often they were flat for a while. I want to avoid this. Assuming I don't Fly the Anafi for a few weeks, how do I keep the batteries at their best? Do I charge it to two bars once a week, no more or less. Or maybe three bars once a fortnight. I would charge it fully before a flight. I also see after a flight the battery should rest for a while, then charge it again. Thank you for any help.
