12 Raith User Guide
BATTERY
Your Raith Midnight houses a high capacity, lithium-ion
battery pack.
Sensors measure different aspects of the battery pack and
communicate this to your Raith Midnight BMS to ensure the
battery is always running at optimal levels.
Hot Weather
When riding your Raith in temperatures above 40°C (104°F)
your BMS (battery management system) will alarm, it will
then shut off when temperature exceeds 45°C (113°F), this
is to keep your battery pack protected from overheating.
In the event this happens, please wait for the battery to cool
down before riding again.
Cold Weather
When riding in colder weather around 5°C (41°F), you may
notice a reduction in range due to how lithium batteries
operate in cold weather situations.
Alarm
Your skateboard is fitted with an audible buzzer/alarm in
case of the following:
Battery/Cell high voltage
Battery/Cell low voltage
Cell difference voltage
High/Low Battery Temperature
A constant sounding alarm will sound if your board is
approaching a high voltage in which your BMS will cut
power to the battery and lose regenerative brakes. If you
hear a constant sounding alarm, stop using regenerative
brakes and use a mechanical method of braking
immediately to arrest speed, discharge your battery more
before using regenerative braking again.
An alternate sounding alarm (1 sound evenly after the other)
will sound if your board is approaching a low cell/battery
voltage. Continued use past the low voltage alarm point will
cause the BMS to protect the battery once the voltage
reaches cut off voltage. This will cut power to the ESC and
cut torque to the wheels. The rider will experience a jolt, it is
not recommended to continue riding the board once the
rider has reached the low voltage alarm.
