It works like this...
Colder = less power and larger voltage drops. (*see below)
Colder = longer shelf life and longer cycles IF used to only about 50% capacity.
(Ultimately meaning less power and more cycles)
Warmer = more power and less voltage drops.
Warmer = shorter shelf life and shorter cycles.
(Ultimately meaning more power and less cycles)
End all is, batteries like warm better than cold. (but not by much.)
Now for motors, it's different...
Motors become more efficient when their temperature is lower and less efficient when their temperature rises.
Ultimately, the average power/cycles in the entire "system" is balanced between colder and warmer temperatures.
Lithium Polymer batteries really hate very cold and very hot.
Lithium Iron Phosphate batteries tolerate cold and hot better.
Lead Acid batteries REALLY hate cold.. As a matter of fact, at about -10F (for an extended period of time), lead acid batteries can actually FREEZE. (that's why it's difficult to start your car in sub freezing temperatures. *see above)
