Motor Controller Recommendations - 84V max - 50A Continuous

I am working though a one (or two) motor kick-scooter design and specifying a reasonably sized motor controller has been challenging until stumbling upon the VESC Project.

I'm looking for some controller recommendations that will pair well with the battery I plan on using:

Battery:
72V nominal voltage (84v Fully charged)
20S10P
40ah
50A continuous discharge
100A peak discharge

I also need the controller to be compatible with a second controller for the second motor; I also need to be able to switch between one motor mode and dual motor mode.

I found a couple 75/100 VESC options (The Trampa one and the Flipsky one), but I'm not convinced it can handle the 84V max battery voltage.

Can anyone help me out?

This controller looks like it's built off the 75/100 platform.  I know they claim its good for 84V even though the original design is only meant for 75V peak. 

Is there anyone that has tried this controller at 84V?

Hi friend, i am also working on a kick-scooter and bought this flipsky 75100 controller, it can work with 20s safely, the capacitors are 100V, on youtube there is a video where you can see it.

Hi, I need to deal with a problem I have. I have a scooter FLJ sk3 2x3500W, battery 20S 72V and I bought the driver FS75100. I have 80A set for each motor.
The scooter rides quite well at the beginning, but after 1 km it loses power. the voltage on the battery is fine, which is causing a sharp do not know falling power! :(
