Battery and charging:
Charging is only allowed at 0°C~45°C, and discharging is only allowed at
-20°C~60°C. The battery must be kept dry. It is strictly prohibited to put the
battery in acidic or alkaline liquid. Rain must be avoided, and it shall be kept
away from fire, heat and high temperature environment. It is strictly prohibited to
reverse the battery's positive and negative poles or damage them, plug in the
battery or let it suffer from short circuit. Please use the original special charger
when charging. The charging must not last more than 6 hours, and the charging
current does not exceed 2A. When not in use for a long time, please keep the
battery in a cool and dry place, and charge it for five hours every month. Users
must follow the instructions when charging, otherwise they will be at their own
risk. Attention shall be paid to the type of battery to which the charger is
compatible and the applicable voltage, and mixing is strictly prohibited. When

charge in a residential building and in an enclosed space or in a hot
environment. When charging, insert the battery first, and then supply the mains
power; when fully charged, cut off the mains power first, and then unplug the
battery connector. When the green light is on, the power shall be cut off in time.
It is forbidden to connect the charger to the AC power supply without load for a
long time without charging. During the charging process, if the indicator light is
abnormal, a peculiar smell occurs, or the charger case is overheating, stop
charging immediately and repair or replace the charger. During the use and
storage of the charger, be careful not to let foreign matter enter, especially avoid
inflow of water or other liquids, so as to avoid short circuit inside the charger.
The charger should not be carried with the vehicle. If it is necessary to carry it, it
shall be placed in the tool box after shock absorption treatment. Do not
disassemble or replace the accessories in the charger by yourself.

Remarks: electric quantity, load, tyre pressure, pavement environment, chain and axle lubrication
degree, etc. will affect the maximum speed; the endurance mileage is measured at a load of 60kg
and a speed of 15~25km/h on flat and hardened road under continuous testing from 100% power
capacity to 0% power capacity; driving habits, temperature, load, tyre pressure, pavement
environment and other factors will affect the endurance mileage.
