Charging The Power Pack
Note: When the motorcycle’s charge indicator is on
the third bar (1/2) MX Dirt or fifth bar (1/2)
X/XU Street Legal, when not under load, the power
pack needs to be charged. Frequent top off charging
is good for the power pack’s life span, so do not
hesitate to charge frequently.
WARNING: Charge the Zero power pack with the Zero
charger. It is possible for lithium ion cells to overheat
and fail.
It is recommended to charge in a location that is
away from combustible materials and in a well-
ventilated area. Avoid outdoor charging of your power
pack in the rain.
The minimum charge temperature is 0°C (32°F).
The maximum power pack internal charging
temperature is 65°C (149°F). If the power pack is
kept in an environment over 65°C (149°F), it will not
accept a charge until it is moved to a cooler location.
Also if the pack has just been run hard, it may
internally be above 65°C (149°F) even if the ambient
temperature is lower. If you experience a pack that
will not take a charge, ensure the internal
temperature is below 65°C (149°F). If the power pack
was recently run and it will not take a charge, the
power pack should cool and begin taking a charge in
around 30 minutes or less.
The max charging temperature cutoff is a power pack
longevity feature. Charging at higher temperatures can
shorten the life of the power pack.
