Problem with many online adverts I read for ESC's ... same with Lipo's ... the ratings are often overquoted ... it's not unusual for an ESC to say eg 30A ... then when you check deeper into it's specs it's actually a 25A continuous max or lower.
Nice thing about the Castle Creations ESC's. I've actually run them at their rated maximum currents without problems or concerns.
But you can NEVER
run them (or any ESC) at over their maximum VOLTAGE rating!
