Troubleshooting

Hot Weather Operation
Operation of the motorcycle in hot temperatures should not
result in any noticeable performance changes. However,
the BMS will not allow motorcycle operation and its
associated power pack discharge above 140°F (60°C), as
measured at the power pack.
In hot temperatures greater than 109°F (43°C), the
charger reduces its charge current to the power pack,
increasing charge time accordingly; the hotter the ambient
temperature, the greater the effect. Above a power pack
temperature of 122°F (50°C), the BMS will no longer allow
charging.
Note: Storing the motorcycle or its battery in direct sunlight
in ambient temperatures above 95°F (35°C) may result in
accelerated permanent decay of power pack performance,
and hence it is not recommended.
Safety Interlocks
If the BMS detects a serious internal fault, it can take either
or both of two actions to prevent damage to the power
pack:

Throttle Disable . The BMS disables the throttle if the
power pack is empty, or if the BMS detects certain
serious internal problems. You cannot ride the
motorcycle until the problem is resolved.

Charger Disable. The BMS prevents charging if it
detects certain serious internal problems - even if the
power pack is connected to a charger and plugged in to
AC power. The power pack cannot be charged until the
problem is resolved.
