9l with new mamba maxx esc

[BrianG]

What vehicle?

Only 8 cells will bring the 9L up to only ~21k rpm, which will work, but not in the most efficient range of the motor. Plus, at low speed, you might have more cogging because the motor is slow even at full voltage. With the 9L, I'd say use 12 cells for optimum motor speed, which is a little on the high side of the rated voltage for the Mamba Max.

The 9XL is even slower, so more voltage will be needed to get to the ideal motor speed. But that motor has more torque than the 9L, so you can gear it up more.

The vehicle being used has a lot to do with it. Since you want to use only 8 cells, this leads me to believe it might be a small vehicle? If so, maybe a MambaMax motor or an S size Wanderer may be suitable.
