Power Pack Empty
If the power pack is completely empty, an error-beep
will sound and the BMS will disable the throttle. You
cannot ride the motorcycle until you recharge the
power pack. If the Power Pack Empty error-beep still
sounds after two hours of charging time, contact
your dealer. Your power pack may need to be
repaired or replaced.
Too Hot
The power pack contains internal temperature
sensors. If the BMS measures excessive internal
temperatures, it will flash an error code and disable
the throttle. You cannot ride the motorcycle until the
power pack cools down. Place the motorcycle in a
cool, well-ventilated location and wait a few minutes
before riding again. If the Too Hot error code still
flashes after the power pack has had time to cool
down, contact your dealer. Your power pack may need
to be repaired or replaced.
Power Pack Unbalanced
The power pack contains many individual cells. The
BMS continuously monitors the cells and tries to keep
them all “in balance” (at the same level-of-charge). If
any of the cells are grossly out-of-balance, the BMS
will flash a Power Pack Unbalanced error code and
disable the throttle. You cannot ride the motorcycle
until the problem is resolved.
The solution to the problem is to plug in the charger
and allow the power pack to charge for 72 hours.
This will allow the BMS to re-balance the cells in the
power pack. If the Power Pack Unbalanced error code
still flashes after the power pack has spent more
than 72 hours charging, contact your dealer. Your
power pack may need to be repaired or replaced.
Low Power Pack Warning
When in the run mode, the BMS provides a Low
Power Pack red warning flash code telling the
operator that the remaining range is limited, and the
power pack should be recharged soon. This is
equivalent to a “low fuel” warning-light on a gasoline-
powered vehicle.
