Description: I tested my wheel spinner and hoist at -20 degrees Celsius outdoors (lovely Finnish weather in January), +20 room temperature, and +60 inside a sauna. How the temperature affects top speed and max hoist weight? Will something break? The spinner results: -20C 3100rpm (7.1V) +20C 4800rpm (8.0V) +60C 4700rpm (8.1V) +20C 4400rpm (fixed 7.1V voltage) The hoist results: -20C 101kg (6.6V) +20C 132kg (7.5V) +60C 95kg (8.0V-8.6V) +20C 101kg (7.6V-8.5V) (motor +60C) +20C 122kg (7.5V)
