Power is measured in watts. You can get the watts by multiplying volts and amps. 96 volts x 650 amps = 62,400 watts (62.4 kilowatts). 144 volts x 500 amps = 72,000 watts (72 kilowatts). That's an incomplete answer at to what would be best for your setup, but strictly speaking the 1239 handles more power based on those numbers. The voltage of your motor, desired top speed, and overall gearing are important factors in this conversation.Hello
Which Curtis controller has more power?
The 1238 with 96v and 650 ampere or the 1239 with 144v and 500 ampere?
The Car is an Porsche boxster 986.
What motor do you have?Helle
Highspeed is Not importand.
Original gearbox with 144v Motor, vs 96v Motor.
I am from Germany and the Motor too.
The 650 ampere Curtis have the big boost.
But the 1239 Curtis have the Power in more RPM.
