I did some more research…prompted by your comments. I could not find the article that I’d read which suggested the “leave 40%”. All the articles and videos I can now locate say “leave 20%” and/or consider 3.5V per cell the minimum.
Percentage is subjective anyway. It is the minimum 3.5V that really matters per the experts. Going lower risks hitting the 3V “damaged” cell voltage.
But, I fly many thousands of flights a year, so I must treat them easy. And I get a year on a new set by rotating 10 batteries through 4 EDFs to achieve this large number of flights on a set. The annual cost of 10 LiPos is still cheaper than a lot of hobbies!
Finally, Most importantly, I prefer to keep a good safety margin for go arounds, too.
I am updating my mental database. 😃
