A Warning about updating VESC firmware!!
Quote By: Benjamin Vedder. Using the wrong firmware will most likely kill the FETs and/or the drv, so when you change firmware you should use some kind of power supply that cannot deliver too much current at first and preferably a low voltage (<20 V).
Only attempt to change the firmware if you are aware of the risks. A failed firmware upgrade can permanently damage the VESC. The enertion warranty doesn’t cover faults relating to failed firmware upgrades.
