500W SMART CHARGER
Instruction Manual

Never use the charger without supervision, please stop using the charger and
refer to the manual for reasons if any functional abnormity.
Keep the charger away from dust, humidity, rain and high temperature,
as well as avoid direct exposure to the sunlight and intense vibration.
Place the charger on a heat-resisting, non-flammable and insulating surface.
Do not use it on the car’s seats, carpet or other similar places. Keep
inflammable and explosive objects away from operation areas of the charger.
Read the instruction manual carefully to be familiar with the features of the
charger, and set proper charging parameters before operating. Setting the
parameters incorrectly will result in damage to the product, personal property
and cause serious injury as well.

Make sure to know the maximum charging current of the battery before
charging, never use excessive current to charge to damage your battery,
which will result in over heat even explosion during the charging process.
The charging and discharging capacity of battery is usually marked with
C value. Multiplying the charging C value and battery capacity equals to the
maximum charging current supported by the battery. For example, for a 1000
mAh battery with a charging capacity of 5C, the maximum charging current
would be 1000×5=5000mA; therefore, the maximum charging current is 5A.
For a lithium battery, if it is impossible to confirm the supported charging
C value, please set the charging current below 1C, for the sake of its (lithium
battery) safety.
The reference relation between C value and charging time:
charging time ≥60 minutes/ charging C value (e.g. it needs around 60~70
minutes to complete charging with 1C). Due to differences in battery
conversion efficiency, the time to complete the charging might be extended.
How to Confirm Charging Current
Power on Q8 smart charger, connect the battery, and short touch
the middle key of the touch board to enter the task setting menu as follows:
Operating the Charger

Charge
Balancing port is strongly recommended when charging lipo battery, which
can make sure to monitor voltage on each cell battery and balance it when
charging. Warning beeper will yell before start charging lipo if in non-balance
mode(no connecting with balance port).
Current setting range: 0.1~20A
The battery type, cell count and charging current are auto set accordingly
when connecting with BattGo battery.
Discharge
Current setting range: 0.1~1.5A
The battery type, cell count and discharging current are auto set accordingly
when connecting with BattGo battery.
Storage
Current setting range: 0.1~20A
The battery type, cell count and storage current are auto set accordingly
when connecting with BattGo battery.
DC Power supply
The charger can be used as a DC power supply when choosing this function,
with adjustable voltage 2~30V, and current 0.5~10A.
The battery type, parameter and current are not optional in this task.

Destroy
Connect the battery to be scrapped, and select the scrap function in task
options, which capable to discharge the battery to 0V.
Current setting range: 0.1~1.5A
The battery type and cell count are are auto set accordingly when
connecting with BattGo battery.

The cell voltage and internal resistance only on display in balancing
charging mode. The BattGo information will display only when
connected to the BattGo battery, and the cell voltage is able to display
without connected to the balance port.

Min. input voltage protection 10~30V: all tasks in operation will be stopped
at once and hint warning of low voltage, when the input voltage is lower than
the input voltage as set up. It will protect the battery from being discharged
when using battery pack as power supply.
Max. input power setting 30~550W: if the input power is smaller than the max
working power(550W), please set up the parameter as the actual output power
as max input, to protect the input power and enable the charger to work stable.
Buzzer volume: The operation sound will be shielded when the volume is off,
except the warning error beep.
Self-test: Enter system setting. select self-test task
Calibration: the input voltage, output voltage and balance voltage of
the charger can be calibrated with this task.
