Click For Summary
Servo motors labeled as "12V" typically require a minimum of 12V for optimal operation, ensuring longevity. However, datasheets often reference performance metrics at 14V, which aligns with common lithium polymer battery voltages. Operating a 12V servo at higher voltages can enhance speed but may reduce its lifespan. Lead-acid batteries provide 12V under load but can reach 14V during charging, which contributes to this voltage discrepancy. Understanding these voltage specifications is crucial for effective servo motor usage and longevity.

12V servos using 14V in datasheet?
I would like to understand why servo motors often state they are a "12V servo" but then in the datasheet they will refer to tests and torque ratings at 14V? I'm assuming 14V is chosen due to common lipo battery voltages, but then why call it a 12V servo motor?

Can you please link to an example datasheet.

A 12V servo expects to operate on a minimum of 12V, and will have a long life. If you operate it at higher voltages it will operate proportionally faster and have a shorter life.

Lead acid batteries maintain 12 volts when loaded, but they have 14 volts while being charged.

Thanks, that makes sense. Here's what I was looking at previously (not exactly a datasheet):

"Voltage must be lower than 14V" 12V nominal and 14V is the max.

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
