Most of the Hoverboard mainboards use a 10S2P LIPO Batteries (36v Nominal - 42v Charged ).<br />
If you want to use a battery with less or more cells in series, change BAT_CELLS parameter in [config.h](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/blob/master/Inc/config.h) (10 by default).<br />

Batteries up to 12S have been used safely in the community, but do it at your own risk.
## Battery level low alerts:
You can adjust the levels to your needs in [config.h](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/blob/master/Inc/config.h).
Default battery level are for safe use of LIPO batteries.<br>
You can adjust the levels to your needs in [config.h](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/blob/master/Inc/config.h) if you want to use a battery with a different chemistry.

## Troubleshooting:
If the board is [beeping](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Diagnostics)
* 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
If the board turns off with the tune:
* 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 shuts down and won't restart
If the board turns off without the tune:
* 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.
