The interesting part is that batteries love warmth and electric motors love cold. (talking from 100 deg to 32 deg)
Pro's and Con's
Batteries..
warmer = more power from battery

Pro = farther distance
Con = reduces recharge life a little


Colder = less power

Pro = better recharge life
Con = slower



Motor....

Warmer

Pro = N/a
Con = possibility of over heating

Colder
Pro = longer life
Con = n/a
