It was a stupid idea to name the unit 75/300 and it makes no sense at all.
75/300 refers to 75V300A…16S rated.
The Flipsky ESC is rated higher in voltage (20S) and the naming should reflect that.
The only reason to use the 75/300 name is making use of existing VESC product reputation and google
ranking. What obviously happens is a confusion of FW, since the VESC 75/300 FW can be found in VESC-Tool. But please never ever use that FW for the Flipsky controllers!
They confuse their customer base in marketing! This Flipsky controller is not a 75/300 design!
The VESC 75/300 is a phase shunt design, while the Flipsky ESC is actually a low side shunt design. Loading the 75/300FW onto the Flipsky “75/300” will very likely damage your hardware permanently. I can only guess that many users will damage their HW because of a very bad naming and marketing decision.
