Hi @rok, -16A is not a lot of current for the brakes, so don't expect to much. -60 for the motor regen doesn't help to much if your battery can only swallow 16A. This weakness is dominant at speed and will get better when you slow down. At top speed your brakes will be limited to -16A, since the motor generates nearly at full system voltage.
The lower the voltage drops on the generator side, the more Amps the motor is allowed generate.
On the battery side the VESC will scale up the voltage again, lowering the currents back to your 16A battery min value.
This means: If your motor generates 32A at 20V (=640W), your battery could be charged with e.g. 40V, 16A (=640W).
In consequence the battery min pretty much defines your brake power at high speed, while the motor min value becomes more dominant at low speed. The further you spread the values apart, the more you will experience a non linear behaviour of the brakes.
I will try to make a Duty Cycle manual together with Benjamin to explain the matter in detail.
So do some test runs in an area where you face no obstacles to find your settings.
Battery min is the bottle neck for strong brakes at speed! This is why you want a strong battery pack allowing fast storage of energy. This is why you want a high P count.
The motor brakes will not stop your board totally! It gets better with sensors, but if your board doesn't move, your motor won't spin and can't generate electricity. If it doesn't generate electricity it doesn't create resistance.
VESC-Tool has a feature called "hand brake", actively braking your motor through the use of a current flow through the motor coils, blocking the motor from spinning up. This consumes energy from the battery!
You can't easily activate it from the remote at this stage.
