 ## Calibration:
 Battery voltage has to be calibrated to have a more accurate reading, for this you need [Debug Serial](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Debug-Serial) to be active
 * Measure battery voltage with a multimeter and write the value * 100 to parameter BAT_CALIB_REAL_VOLTAGE in config.h
-* Turn the board on and wait for a few minutes for the Battery ADC to stabilize
+* Turn the board on and wait for a minute for the Battery ADC to stabilize
 * Read value BatAdc or 5 from Debug Serial Output and write it to parameter BAT_CALIB_ADC in config.h
 * Save, compile and flash the board
 * Value BatV or 6 in Debug Serial should match with the measured battery voltage now
