No that I am aware off.
Is it the "normal" decharging after some days, "just" quicker?
And is it stopping on 65%?
How old are the batteries?
Did it happen with all like "last time/yesterday all was ok, today ALL OF THEM decharging ...."?
You may want to open a ticket with Parrot - I believe batteries have a 6 month warranty.
FYI... I have a battery that what just a little over 6 months - well taken care of and not that many charge cycles, around 30 or so
It takes a full charge and shows 100% capacity with 100% charge... but is drains around 20% per day until it is completely drained
I have retired it. Good luck
