Hi. We are building a hovercraft and I have a question regarding the battery voltage we should be using to power the two DC motors we will be using. To run the two BLDC motors we are using 2 BOOSTXL-DRV8301 motor drivers, which take 3.3 V each. We are trying to figure out what voltage dc battery should be used to power the motor drivers and dc motors most efficiently. Any feedback would be helpful. Thanks
