If the battery voltage falls below Undervoltage Rollback Start , the RHINO2 reduces the
maximum throttle input value, so the user cannot ask for full speed anymore. This
l
protects the battery,
l
gives the scooter a longer range before the battery is completely empty, and
l
gives the user a physical warning that the battery is almost empty before the battery
is damaged.
The scooter will drive slower but should still be able to climb small obstacles such as curbs.
If the battery voltage falls below Undervoltage Rollback End , the scooter stops driving
because the throttle is reduced to zero.
