Battery losing power

[Alex in Devon]

Hi
Can someone tell me why it is that having flown, I will charge up my batteries to full, but when I go to fly again say 3 or 4 days later, they are down to only 75%

Thanks

How many days do you have them set to discharge? I left mine at 10 days as I'll fly it at least once a week.

Fwiw, I had mine stored in a hot car and the battery was down to about 78% the next day and flight time was short even though it was charged the day before. It's been over 100 degrees here so car might be a lot hotter and the battery cooked. Black case wasn't cool either.
