[Shop-talk] Electrical question

[Brian Kennedy]

It's all about temperature. 2X the voltage 4X the power. There are other
variables as well and it would be a science project to find out how much
overvoltage and for how long before you damage the motor. You may also
partially damage the motor and shorten it's life at 12V.
