⚫
When you use the battery for the first time, please run down the battery as much
as possible, and then charge it fully. It will be better to use it 2-3 times to ensure
that the actual capacity of the battery and meter are more accurate.
⚫
After the first time, try to keep the battery level not less than 20%, and charge it
timely, which can extend the battery cycle life.
⚫
With the increase of battery use frequency, the actual capacity of the battery and
the battery level indicator on the meter will be incorrect. Please fully charge and
discharge the battery regularly (no more than 3 months). The internal battery and
intelligent system can automatically calibrate the power to improve the experience.
⚫
When riding normally, it is recommended to use low-speed gear, start slowly and
twist the throttle grip slowly to accelerate gradually, which can extend the range.
⚫
It is recommended to check power plug of the battery every two months to confirm
whether there is carbon deposit and blackening caused by oxidation on contact
reed. If yes, please go to the local dealer for inspection.
⚫
Keep the battery from raining or water flushing, do not soak the battery in water.
Do not ride the vehicle when the water level is beyond the bottom of battery
compartment. Otherwise it may cause the water to get into the battery, internal
short circuit, and permanent battery failure. In this case, it is strictly prohibited to
charge the vehicle or the battery. Otherwise, it will cause the battery to catch fire,
burn and explode.
Notes for charging use
Please confirm that the battery
Please keep it at the ambient
model is the original one
temperature of 0 ℃-35 ℃
before use
Do not use other brands or other types of batteries for charging the battery.
⚫
The power level rises faster in the early stage of charging and slower in the later
stage, which is the procedure set for charging safety and is normal.
⚫
When you charge the battery in winter, the outdoor temperature is low, and when
the environment is below 0 ℃, the charging process is slow, which is normal.
Please place the battery in a suitable ambient temperature for charging to ensure
charging effect.
⚫
During the charging process, some chargers with aluminum shell may have
temperature rise effect, and the surface temperature is high, which is a normal
phenomenon. Please rest assured to use it. Please keep the children from
touching it.
Notes for using charger
⚫
Charger is limited to indoor use. During the charging process, the charger and the
line shall be strictly prevented from being exposed to rain or water.
⚫
When charging the battery, plug the battery connector first, then plug charger
power connector to household outlet; When it is fully charged, please cut off the
charger power connector and pull out the battery plug.
⚫
During the charging process, if the indicator is abnormal, the odor appears or the
charger casing overheats, the charging should be stopped immediately. The
charger should be repaired or replaced.
⚫
Do not disassemble or replace the components in charger by yourself.
⚫
Never charge the battery in a confined space, under direct sunlight or high
temperature environment. The charger must not be placed in the seat
compartment.
⚫
When replacing the charger, it shall be matched with the battery model.
Storage environment
⚫
Please store the battery at an ambient temperature of 0℃ to 25 ℃. Do not store
the battery in an environment above 40℃. Otherwise it will cause irreversible
capacity decay of the battery. If the vehicle is not used for a long time (such as in
winter, summer or other special circumstances), the battery shall be taken out and
stored separately, and shall be maintained and charged regularly. Otherwise, the
battery capacity may be completely exhausted, resulting in irreversible damage.
For such problems, battery failure will not be covered in warranty agreement.
⚫
The most suitable storage power of the battery is 50%. If the capacity is lower than
10% or higher than 90%, long-term storage will result in irreversible capacity
decay of the battery.
For self-power consumption protection mode for the safe storage of lithium battery, the
technical standards are as follows:
Do not let charging time
exceed more than 12 hours
(1) If it is not used for a long time and stored in the vehicle (without unplugging battery
plug), the safe period is up to one month. Otherwise, it may cause battery to be under
voltage and the problem cannot be fixed. (2) If it is not used for a long time, store it with
no less than 50% power or put it in the vehicle (unplug battery plug), the maximum
safety period is 3 months. Otherwise, it may cause battery to be under voltage, and the
problem cannot be fixed.
Avoid storing the battery in a location where there is a risk of dropping it, as dropping
may cause uncontrollable damage to the interior of the battery and may result in heat,
smoke, fire or explosion of the battery.
Battery low voltage and under-voltage caused by the above improper use are not
covered by warranty agreement.
