To Mac, or not to Mac?

[rsilvers]

I recently finished my first build enough to ride it and have about 30 miles on it. I bought the 500W Mac 10t with 36V frame battery pack and 25A controller. In the Cycle Analyst I set the max watts to 500 and max amps to 25. It seems people are running their Macs above the wattage specification for the motor. Is that correct? How high can you go without risk to the motor? 25A x 36V would be 900 Watts. Can I set the max watts in the CA that high?

A few things I picked up by reading what others have said: It depends if you have the new gears or the old gears. If you have a CA, you can limit how fast the power comes on, and that should allow a higher watt limit while still protecting the gears as they take a beating from stand-still. Em3EV suggests an amp limit of 30. At 48 volts, that is 1440 watts. With a CA and a temp-sensor, you can have the power automatically scale down if the motor gets too hot.
