This is a quote from the Castle Creations website:
Quote:
Max input voltage for ESC: 3s lipo or 12 cell NiMH/NiCah
Max RPM for CM36s motors: 65,000 rpm
4600Kv motor max voltage: 4s
5700Kv motor max voltage: 3s
7700Kv motor max voltage: 2s
The Kv of a motor is the number of rpm’s it will turn per volt of input. So the 4600Kv motor will turn 4,600 rpm per volt of battery. On a 6 cell pack we can presume good cells are holding around 1v per cell, so 6v x 4600Kv = 27,600 motor rpm. If we use a 4s lipo pack, lipos carry about 3.5v per cell under load, so 3.5x 4 = 14v. And 14v x 4600Kv = 64,400 motor rpm . This is right at the top of the motor rpm limit and is OK, but is beyond the voltage limit spec of the ESC and cannot be used.
