Amps, Watts, and Volts, oh my!

Amps, Watts, and Volts, oh my!

Fun fact, the word horsepower isn’t random. It really came from horses! The term was created by Scottish engineer James Watt, to compare the output of steam engines with the power of work horses.

Ever wondered how to compare gas engines to electric motors? An electric motor’s power is rated using watts instead of horsepower. It’s broken down like this:

1 horsepower = 745.7 watts

So, how are you supposed to figure out the watts? All you need to do is take your amp draw and multiply it by your voltage!

Let’s use an example! At 5 amps, a 14.8 volt battery would deliver 74 watts of power!

Just remember, amps x volts = watts! You can take your total watts and divide it by the voltage of your battery to determine the amp draw. Connectors and ESCs are rated based on amps, while motors are rated based on watts. This quick battery math will help determine the best motor, ESC, connector, and battery for your specific setup!
