protect both the charger and the power supply unit against overcharging and does not require
supervision. It may be used over an input range of 110V/60HZ to 220V/50Hz. and carry CCC,
CE, and cUL or cTUV safety certification. The charger, power supply, motor and electrical sys-
tems are protected by a high power circuit breaker.
Notice and Warning: (Pay particular attention to any text highlighted in red.)
The PSU (Power Supply Unit) is a key component of the electric bicycle power system. We use
only UL Recognized premium quality batteries designed for long life. Fully discharged batteries
can be recharged up to 400 times. To prolong the life of the batteries always recharge after
use. Conserving the use of your power supply to no more than 80% discharged as indicated on
the instrument power meter will greatly extend the life of the batteries and under normal cir-
cumstances will exceed 400 recycles.
Do not store the charger or power supply or charge the battery in ambient temperature envi-
ronments below 14
o
F (-10
o
C). Prolonged exposure to below freezing temperatures will change
the electrical characteristics of the charging unit causing possible serious malfunction.
Application and Use Practices:
Do not fully discharge the battery supply. Recharge after each use to prolong battery life. Ex-
tensive long term in-plant testing has revealed that frequent recharging, avoiding full dis-
charge, will prolong battery life to approximately 9,500 miles (15,000km) of regular use.
The efficiency of the batteries is influenced by temperature. The power supply will function bet-
ter in warmer to hot temperatures. At temperatures below 32F (0℃) battery performance may
decrease more than 1/3. Full functionality and power density will be restored when the sur-
rounding temperature rises to 68F (20℃).
Frequent stopping and starting, riding uphill, riding against the wind, on muddy roads continuous
use of lights and accessories while not riding, or carrying an additional passenger or extra cargo
are all factors that will reduce the travel distance per charge of your Veloteq.
If the electric bicycle or PSU is stored for a prolonged period it should be fully charged prior to
storage. We recommend that the PSU be removed and recharged at intervals of 20 days during
the storage period to prolong battery life and prevent sulphication of the battery cells. Sulphi-
cation of the battery plates can be compared to the rusting of metal parts. It occurs when a
discharged battery is left in an uncharged state. The batteries used in your electric bicycle do not
have “memory” however all batteries self-discharge while not in use.
Use or storage at temperatures higher than 140F (60℃) such as unventilated storage in high
summer temperatures, will adversely effect the normal working functions of the electric bicycle.
Sudden relocation of the electric bicycle from a cold outside area to a warm interior may result in
crystallization of electric components. Before moving from a cold exterior to a heated interior,
remove the PSU and permit natural cooling and dissipation of any crystals.
The electric bicycle may be ridden in both rain and snow, however under no circumstances allow
it to be immersed in water. Immersion in water such as deep puddles may cause the controller
