1. Do not use the charger in an unattended manner, in case of any functional abnormality,please
stop using it and refer to the manual.
2. Keep the charger away from dust, humidity, rain and high temperature, as well as direct expo
sure to sunlight and intense vibration.
3. Input voltage of the charger is 10.5-30V DC. When connecting to the power supply, make sure
that the input voltage match the operating voltage range of the charger.
4. Please place the charger on a heat-resisting, non-flammable and insulating surface. Do not
use it by placing it on the car's seat, carpet or other similar place. Keep inflammable and
explosive objects away from operation areas of the charger.
5. Make sure the heat dissipation hole at the bottom of the charger is not covered while in use,
and ensure the cooling fan smoothly extracts heat.
6. Please fully understand the charging and discharge characteristics as well as the battery‘s
specifications. Additionally, set up proper charging parameters in the charger. Incorrect
setting of parameters can cause damage to the charger and battery ,even give rise to
disastrous consequences such as fire and explosion.
7. When charging or discharging is completed, please first press the speed shuttle key to terminate
the current task, then remove the battery when the charger shows the standby screen.
1、Connect power supply to the charger, wait for the system to
complete its self-checking ;
2、Choose the channel that is linked with the battery ;
3、Through scrolling the Speed Shuttle key and the screen to set
the task parameters suitable for the battery ;

How to conform the charging current
Operative Skills
It is important to know the maximum charging current of the battery before charging as
excessive current could influence the life span of battery ,even cause damages. In addi-
tion, excessive current can cause heating even explosion of the battery during the
charging process.
The charging and discharge capacity of battery is usually marked with C value. Multiply-
ing 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, its maximum charging current would be l000 * 5 = 5000mA; that is , 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 (it therefore needs around 60~70 minutes to complete
charging with 1C). Due to the differences in battery power conversion efficiency, this
period of time to complete the charging may be extended.
1. Connect power supply to the charger and
wait for the system to complete its self-check-
ing. In standby interface, connect well the
battery to the charger. Short press the Channel
switch key to choose whatever channel prefers
. After having chosen the channel, short press
the speed shuttle key to pop up the “ Task
Settings “ menu ;
2.2.When a task is being executed, short press
the speed shuttle key to pop up the " Adjust
Task" menu to adjust the task’s current ;
3.Long press the Channel switch key can end
the task of current channel quickly or enter the
"Task Settings" menu of the channel .
