I would like to introduce JetFleet products.
More info is here:
For now, we have achieved:
JetFleet H4 LEDs - the “most efficient,” ultra-bright LEDs where every LED is standalone addressed. These LEDs are used in Onewheels, and we are also working on a prototype to mount them externally on eBikes, eScooters, and eSkates. Now it is a great option for DIY enthusiasts.
Controller JetFleet F6 - VESC-based controller available in 20S, 24S, and 32S versions.

Wow i was checking these vescs the other day. Didn’t know they were made by an esk8 forum member!
They look very nice! Do you make them in Europe?
We are from Slovenia. Designed and tested here, mass produced in China. Controller was part of my UNI thesis project.
Is there a minimum voltage for the optimal operating range for these controllers?
It’s pretty commonly known that VESC architecture is more optimal closer to it’s voltage limits than say at 20% or 50% of them.
Being 32s this covers a lot of battery configurations. I’m curious how well it’ll perform at 20s or 24s.
There is no optimal minimum voltage. The minimum voltage is 13V, but I prefer at least 24V.
If we ignore everything else and focus solely on MOSFET resistance, we can determine the following approximate values:
~1.2mΩ for a 100V MOSFET
~1.46mΩ for a 120V MOSFET
~2.1mΩ for a 150V MOSFET
This means the 24S version generates 21% more heat, and the 32S version 75% more heat than the 20S version when pushing the same amount of current.
In reality, the difference is smaller due to other contributing factors. However, for now, even the 32S version is more than sufficient for the MXUS 3K Turbo 4T.
