Higher = More power. Too much power is not recommended for battery and motor life.
This value does not affect top speed.
This is your power limit at full battery voltage. The scooter might use more current to compensate for a lower battery voltage.
All selectable ​​values were tested at stock battery voltage and caused no damage to the tested scooters. However, you should select a value considering other factors such as elevated ambient temperatures (e.g. in summer), differences in component quality or battery mods.
