Operation
Operation Instructions
• WARNING - Only charge the battery by following all
safety descriptions. Please read and follow the
instructions for using the battery charger.
• CAUTION - The battery packs are partially charged and
set to sleep mode before they were shipped; in order to
wake up the battery and ensure that the battery has full
and sufficient power, please charge your battery pack fully
before using it for the first time.
• All Hyena Chargers only use genuine Hyena batteries
and battery packs, or battery packs approved for use with
your e-bike by the manufacturer, and purchase only from
reliable sources.
• Use of uncertified battery packs may result in death or
severe injuries.
• Charging is restricted to certified Hyena lithium battery
packs. The battery pack voltage must comply with the
charger output voltage; otherwise, it might result in risks of
explosions or fires.
• CAUTION - Charge the battery indoors to avoid
exposure to rain or wind. Do not use outdoors or in
environments with high humidity.
• WARNING - Be sure to hold the power plug steady
instead of hold the cord when connecting or disconnecting
from the electrical outlet. Failure to do so may cause a fire
or electric shock.
• If the following symptoms are observed, stop using the
device and contact the place of purchase. A fire or electric
shock may be caused:
- If heat or acrid-smelling smoke is coming out from the
power plug.
- There may be a bad connection inside the power plug.
• Do not place the battery charger on the floor or other
dusty places when using it.
• Place the battery charger on a stable surface such as a
table when using it.
• Do not place any objects on top of the battery charger or
its cable. Do not place a cover on it either.
• Do not apply excessive tension to the cables and
charging plugs.
• Do not touch the metallic parts of the device or the
power plug on the AC adapter or other parts when the
charger is wet, electric shocks may occur.
• Use only a 100-240 V AC electrical outlet, do not
overload the electrical outlet with appliances beyond its
rated capacity.
• If the electrical outlet is overloaded by connecting too
many appliances using adapters, overheating resulting in
fire may occur.
• Do not damage the power cord or power plug. (Do not
damage, process, forcibly bend, twist or pull them, bring
them near hot objects, place heavy objects on them or
bundle them tightly together.)
If they are used while damaged, fire, electric shocks, or
short-circuits may occur.
• Do not use the battery charger with commercially-
available electrical transformers designed for overseas
use (travel converters). They may damage the battery
charger.
• When charging the battery while it is mounted on the
bicycle, do not move the bicycle. The battery charger's
power plug may come loose and not be fully inserted into
the electrical outlet, resulting in a risk of fire.
• When charging the battery while it is mounted on the
bicycle, be careful not to trip over the charger cord. This
may lead to injury or cause the bicycle to fall over,
damaging the components.
• CAUTION - According to ECP, when the battery is in
over-charged/over-discharged conditions, the battery will
automatically disconnect the circuit for safety protection.

Charging Instructions
• Check your battery pack before using it for the first time.
First, you must turn on the battery pack; if the charging
LED did not light up, it means that this battery pack might
be damaged.
• Make sure to charge the battery pack fully before using it
for the first time.
• Do not try to use or charge damaged battery packs.
When charging, do not place any items 50 cm around the
battery, make sure the battery and the charger are on a
fireproof surface.
• Do not leave batteries in the charger for more than 24
hours, if the charging cannot complete in 24 hours,
contact your local bicycle dealer for assistance.
The battery pack can be charged under any power mode;
interrupting the charging process will not damage the
battery pack.
• CAUTION - The battery packs are partially charged
before they were shipped; in order to ensure that the
battery has full and sufficient power, please charge your
battery pack fully before using it for the first time.
Charging
• Plug the charger’s plug into an outlet (100-240V), using
the appropriate plug for the country’s standards.
• Uncover the charging socket on the battery, then
connect the charging plug with the charging socket on the
battery.
• When charging is complete, disconnect the charging
plug from the battery socket.
• Unplug the charger from the wall socket.
• Make sure to close the charging port cap after charging.
If foreign matter such as dirt or dust adheres to the
charging port, there is a risk that the charging plug will not
fit into the charging port.
• If the battery has become completely empty, charge it as
soon as possible. If the battery is left uncharged, it may
cause the battery to deteriorate and become unusable.
• CAUTION - When possible, you should charge the
battery in an area with a smoke detector or make sure
someone is taking care of the battery during the charging
process.
• CAUTION - Do not place the battery charger at locations
that are easily accessible to children.
Charge the Battery Pack Before and After Storage
• When you do not use the battery pack of the e-bike for
extended periods of time, charging the battery to 30-60%
will be the optimum storage condition.
• Confirm the charge status again after six months; if the
remaining power of the battery pack is less than 30%,
charge it again to between 30-60%.
• CAUTION - If the battery is stored under the condition of
lacking power, the battery pack may be damaged and the
power storage capacity of the battery pack itself will also
be affected significantly.
