Thanks to Duster and others for providing the lessons, I sure need 'um. I plugged it into a spread sheet so I can easily compare the different batteries.

What I want to know is how to rate the current draw of a BL motor so you can judge what battery capacity you really need. I haven't stumbled on any formulas for that yet.

I see a lot of people concerned with the ability of a ESC to pass massive current, yet it will only be required to pass whatever is demanded by the motor. I see the motor draw as the primary factor in setting up the system.

Also, I'm assuming even though you motor may only draw ~75 amps max, if you have a 125 amp discharge capacity the extra just ends up as more run time.

It's also not clear which factor (mAh or C) has a larger affect on burst discharge (punch). Forgive me if it should be obvious by the math........
