## 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 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
* Turn the board on and wait a minute for the Battery ADC to stabilize
* Read value BatAdc(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
* Value BatV(6) in Debug Serial should match with the measured battery voltage now
## Troubleshooting:
If the board is beeping
* Make sure you have updated the number of cells in config.h if you use a battery with less cells in series
* With a battery of low quality/health, pulling a lot of current will result in a big battery voltage drop and can lead the board to turn off
* With a battery of low quality/bad health, pulling a lot of current will result in a big battery voltage drop and can lead the board to turn off
If the board shuts down and won't restart
* The battery BMS will shut the power off if too much current is being drawn
