Hey Guys,
Here's an idea. I know this method doesn't give you voltage number settings, BUT...........
Couldn't you just go into the Throttle curve page. On the upper end of the scale, limit full throttle to a set percentage of what "full" throttle used to be?
You don't have to flat line the throttle curve at the top, just make it peak at say hmmmm........
14.8 volts divided by 22.2 volts = 66 percent.
This isn't going to limit amp draw IMO, but it will limit the maximum volts that will be sent to the motor.
I hope this helps.
