Battery Power Requirements for R/C Vehicles

This javascript/HTML calculator is based on the original work of Nick Maslowski, re-styled to fit the site's scheme. It will calculate how much power (watts) and amperage is needed to go a certain speed in a specified amount of time, the motor KV and RPM necessary, and a few other tidbits of information.

Fill in all of the fields values and press the "Calculate" button to display the results. Some fields can be automatically filled with pre-determined values by selecting from the associated drop-down list.
