Mi application is as follows: The VESC uses a 28V battery to drive a very low kv (80) motor to crank start a 110cc internal combustion engine in an RC plane.
After that, the VESC should be completely unactive (high impedance state, no driving, no regeneration).
The problem is, that at full throttle, the combustion engine can reach 7000rpm, which means 88v at electric motor terminals.
My question is: Can the hardware of VESC tolerate this voltage without being damaged?
If not: Can it be modified in any manner (mosfet change, etc) so that it can tolerate this voltage.
Thank you in advance.
