I have received a ton of questions to various videos that look something like this...
Yes, this is an actual comment on one of the videos.
I want to make things perfectly clear for future comments, and hopefully help some people in the process. KV is a very simple term. The K equals RPM or Revolutions Per Minute. V equals volts. So if you have a 1000kv motor and you give it one volt, it will spin 1000 rpm. If you have a 2500kv motor and you supply 2 volts, it will spin 5000 rpm. You take the KV rating of the motor and you multiply it by the voltage that you are going to apply to it. I always use the peak charge voltage as my base since it is the largest and thus the fastest.
In no way can I tell you what ESC to use with a motor by the KV rating. In no way can I tell you what battery to use with a motor by the KV rating. It IS physically impossible!
In order for me to calculate what ESC and Battery to use with a motor, I need to know the voltage you are going to run the motor at, what voltage the motor is rated for (yes, I have had people wanting to put a 6s battery on a 3s motor). With the voltage or the motor and the wattage of the motor, I or anyone else can calculate the amperage (Watts divided by volts equals amps) and give you suggestions on what to run.
I created this thread so that I can link to it for future comments of this nature. In summery, KV is RPM/Volt. In order to tell you what ESC or battery to use, I need to know the voltage rating and the wattage of the motor, and these need to be PEAK ratings for the wattage.
