100V vesc

Hi guys , I've one answer. 
I've seen the schematic for vesc 75300, but anyone know what upgrade that schematic need for support 20s? 
The original chip INA240 can support max 75v I've seen, any solution?

"#define INVERTED_SHUNT_POLARITY" may be needed to define as in hw config.

Just remove the line about HW_HAS_PHASE_SHUNTS and you should be good.
