How does cold weather typically affect a lithium battery used in a small drone?
- A.Capacity and available power drop, so flight time is reduced
- B.Capacity increases and flight time becomes longer
- C.Cold has no measurable effect on battery performance
Correct answer
A. Capacity and available power drop, so flight time is reduced
Why
Low temperatures slow the chemical reactions inside lithium cells, reducing voltage and usable capacity. Warming batteries before flight and planning shorter flights helps manage the loss.
