*In loaded operation, the voltage of battery is reduced, and LED changes correspondingly; the
higher load power is, the more obviously LED changes.
* In loaded operation, in case that the indicator light “Power” (displaying output power) flickers
continuously and the buzzing occurs for over 5s, then the equipment is locked automatically, which
indicates that the existing electric quantity of battery cannot afford the load, so please reuse if after
charging.
Status LED Lamp Alarm
During charging the flash, the instantaneous power may be increased by more than 3 times, e.g. for
100WS flash, its transient current may be equal to that of a 300W lamp. Therefore, when using
certain flashes, the indicator light “Power” may flicker with short buzzing, which is normal as the
instantaneous power of the flash has exceeded 750W.
If the indicator light “Power” (displaying output power) flickers continuously, occurring buzzing for
over 5s, the equipment will be locked automatically.
After locking the equipment automatically, you only need to turn off the mains switch, and then turn it
on to reuse.

2.2 Mode Switch
LP750X Inverter is equipped with two operating modes including “Normal” (normal mode) and
“Flash” (flash mode). Users can choose one of the working modes according to the loaded
machine.
The “Flash”(flash mode) is specially designed pursuant to the performance characteristics of
flashes, also supporting the use of electrical appliances with rated power; however, no power-
down mode is provided and the standard battery can stand by for 13 hours continuously in this
mode.
To the electronic products that continuously output rated power, , it is recommended “Normal”
(normal mode) should be used, because it can save electricity; in this case, the standard battery
can stand by for 48 hours continuously; in the mode, flashes cannot be used.
As for detailed data, see the following “Introduction to Function Mode”.
2.3 Main Switch
“OFF” refers to power off;
“ON” refers to power on; at the moment, the equipment can be used;
“USB” refers to USB charging starts, at the moment, the USB indicator is lit on and portable
products can be charged e.g. iPhone, iPad, etc. There is no AC power output in USB mode. USB
1/USB 2: output 5V/2400mA.
2.4 AC Output Socket
* Two AC output sockets are parallel, and each of them can output the maximum power.
* AC output standard voltage is 230V/50Hz. If additional requirements are from some special
voltage, please consult our relevant personnel prior to purchase.

Operation Instruction Operation Instruction
1. Battery Installation and Detachment
Installation:
1. Insert the battery into the
Battery Compartment.
2. Push it in until it is locked.
Detachment:
1. Push up the button and the battery handle will
pop out.
2. Hold upward the button and pull out the
handle to remove the battery.
1.1 Charging Source
The charger can connect to 100V-240V AC power supply.
1. Take out the battery.
2. Insert one end of the charging connect cable into the charging socket of the inverter.
3. Connect the AC output plug of charging power cable to the charger’s AC input
socket, and connect the other end of AC input plug to connect any AC power source
to start charging.
Note: please disconnect the power source in time after charging finished.
1.2 LED Lamps of the Charger and Battery
(1) The red lamp is flickering: No charging;
(2) The red lamp is lit continuously and green light blinking: In charging;
(3) The green lamp is lit: Completing charging.
Note: If the battery has been spent, about 3.5 hours is needed to charge it fully. After
charging, please pull out the charging connecting cable. To ensure the expected
service life of battery, please charge it fully in the following special cases:
* When the inverter alarms in low battery.
* Reusing the battery after nonuse beyond 100 days.
2. Connecting Inverter LP750X
Move the button “Main
Switch” to “OFF” (power
off).
Insert the load into the “AC
Output Socket”.
Move the button “Main
Switch” to “ON” (power
on).
Move the “Mode Switch”
to “Flash” (flash mode)
or “Normal” (normal
mode).
Turn on the load power
supply to use.
Note:
* It is recommended that the modeling light should be closed while using it in a flash,
because the modeling light may use up the electric energy in the battery of Inverter in
short time.
* Move the button “Main Switch” of power supply to “ON” (power on); at the moment, the
buzzer gives out buzzing, which indicates the Inverter will perform internal detection
automatically, and LED indicator lights will display different colors. Finally, the buzzer
gives out another buzzing, and the indicator light “Status” (working condition) is green,
which indicates the Inverter begins to work normally.
* In case of outdoor photography, the Inverter can be placed in a waterproof bag to avoid
any dust, sand and water. At the moment, users can open the “bag mouths” on both sides
of waterproof bag to hang it at the braces, avoiding blocking and sealing “Air Inlet of
Cooling Fan”.

Connecting Other External Storage Batteries
1. Connecting an External Battery
Use an external power cable (separately purchase) to connect the inverter to external
battery(battery voltage 11-15V). In case that an external battery is used, generally, the
capacity of an external storage battery is larger, so the Inverter can work longer than that
in using the built-in battery. You can purchase and prepare external batteries with
different capacities according to the actual demand to elevate the continuous service time
of the product.
* Take the LEADPOWER Inverter out of the water-proof bag.
* Reconfirm the Inverter is in the mode of shutdown.
* Connect the power input port of controller with external power source output port of
battery.
* Connect the external battery and power source by external battery power cable. Please
note the anode and cathode.
* In case that the above connection is correct, move the “Main Switch” of Inverter to “ON”
to operate.
2. The Standard of External Power Cables
2.1 Purchasing GODOX standard 2M connecting cables
• Please ensure the anode and cathode of external battery aren’t reversed;
otherwise, the fuse of inverter may be burned and even the inverter is
damaged irreversibly. We are not responsible for the warranty of any fault
caused by the reversion of anode and cathode.
• No operating in the environment with any flammable and explosive gas.
• Make sure the power source input port of controller is connected with
external power source output port of battery.
WARNING
Note:
* When the Inverter is connected with an external battery, you only need to connect the
Inverter with battery by connecting the inverter to any external battery by the power
cable of external battery and connect the power input port to the external power output
port; in this way, the external battery will replace the battery to supply power.
* The required voltage of external battery is from 11V to 15V.
* [+] represents anode, while [-] represents cathode.
1. Normal Mode
In the mode, the flash is inappropriate to be used, but supporting the use of any electrical
appliance with rated power. The maximum power of used equipment is 750W (3 minutes)
with energy-saving function.
In case that the service power exceeds 750W, the indicator light “Power” (displaying output
power) will become red and flickering, meanwhile, the buzzing occurs.
Introduction to Function Mode
Note: When the loaded power is below 45W, please use flash mode. Otherwise, the
inverter will automatically enter energy-saving function in the normal operating when the
loaded power is below 45W and there is no AC output.
