I checked mine and it seems ok from the HW side.
I upgraded a 48V 15A FOC controller with the FS for my driftboard. I will set battery amps to 100 and start with 80 phase amps. If everything works out I will increase to 100pA and then to 120pA.
I don’t know if the motor will hold up since I’m going 20S on a hub motor, but otherwise I will buy a bigger one.
The HW of the FS controller seems legit so far. TO 220 fets and ARM STM32 MCU are industry standard. I’m just a little concerned about the amount of fets, since there are just 6. My other 100V VESCs are rated with 200A/300A but they have 18 fets. I’m really curious how the FS will do under 100A/120A.
