* Value BatV(6) in Debug Serial should match with the measured battery voltage now
## Troubleshooting:
If the board is [beeping](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Diagnostics)
If the board is [beeping](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Diagnostics) because of low battery level or turning off with the melody
* Make sure you have updated the number of cells in [config.h](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/blob/master/Inc/config.h) if you use a battery with less cells in series
* [Calibrate the battery voltage](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Battery#calibration)
* With a battery of low quality/bad health, pulling a lot of current will result in a big battery voltage drop and trigger battery low alert
* With a battery of low quality/bad health, pulling a lot of current will result in a big battery voltage drop and trigger battery low alerts. You can use a better battery or several similar batteries in parallel
* Reducing the [battery low levels](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Battery/_edit#battery-level-low-alerts) can help but going too low can be risky for your battery
* You can reduce the [current limit](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Setup-current-and-speed-limits#current-limit) but you will lose power
If the board turns off with the melody:
* 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. You can use a better battery or several batteries in parallel. Adjusting the [battery levels](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Battery/_edit#battery-level-low-alerts) can help but going too low can be risky for your battery.
If the board turns off without the melody:
* The battery BMS will shut the power off if too much current is being drawn
* The battery BMS will shut the power off if battery is fully charged and too much current is flowing back (regenerative braking)
You will have to unplug the battery and plug it again.
If the board turns off without the melody, the BMS is shutting the power off:
* You might be drawing too much current. You can reduce the [current limit](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Setup-current-and-speed-limits#current-limit) not to trigger the BMS over-discharge protection but you will lose power
* It can happen if your battery is fully charged and too much current is flowing back (regenerative braking), it can trigger overcharge protection
You will have to unplug the battery and plug it again
