Hi ESFMs,
I'm trying out different controllers lately and recently, I tested out what should be a downgrade from my previous controller.
My previous controller is a 12 fet, 30 amp max with a 17 amp continuous rating.
This new controller is a 9 fet, rated at 12 amps continuous with a max of 25 amps.
I was expecting a power cut but instead, its performing at about the same top speed (45 kph) and acceleration. In fact, I sometimes wonder if it doesn't have a little more.
The only real tangible difference is the take off. If I throttle from a dead stop (and I usually try not to) it struggles a little more.
I also noticed that the discharge rate is pretty much identical. I would have thought that being rated lower than my bigger controller, I would be saving energy too. I guess it doesn't work like that.
Can someone explain to me the impact of different amp draws and also shed some light on why I'm not experiencing a significant change in performance? Is a 5 amp drop too small a change for any noticeable difference?
