Overview
Product Components:
1. Boost Power switch (Boost code)
2. LCD Screen Monitor (Blue Backlight)
3. Charging Slot #1
4. Charging Slot #2
5. AC Power (100V ~ 240V - 50 / 60Hz)
6. DC 12V / 24V Power Input Socket
7. USB-A Power Out 5V ~ 2A /10W
IIntelligent charging systems integrate the control systems within the charger and the
electronics within the battery to allow precise control over the charging process. As a safety
precaution with high-capacity batteries, a pre-charging stage is used. The charging cycle is
initiated with a low current. If there is no corresponding rise in the battery voltage, it indicates
that there is possibly a short circuit in the battery (zero volt activation). Constant current
constant voltage (CC/CV) charging mode effectively charges lithium batteries. When a lithium
battery is nearly empty, we take constant current to charge it. The charger CPU automatically
adjusts the charging current to be lower than the maximum charging current that the battery
can accept. With constant current charging, the battery's voltage rises slowly until it reaches a
maximum voltage at this point, the charger switches the charging method to "constant voltage"
and reduces the charging current. When the battery is fully charged, this state is stopped.

BOOST Button
1. Plug the supplied bower bord into the Main AC power outlet.
2. Plug the other side of the supplied bower bord to the charger AC Power (picture B).
3. Charger RP-DC50 turns ON automatically.
4. The LCD bcreen will illuminate blue, and the HEDBOX bogo will turn on (picture D).
5. Use the exchangeable battery bharger plate (purchase it separately) and gently put /slide
in one of the charging sockets.
6. Use the appropriate battery that you want to charge and put it on the battery charger plate.
7. The charging process starts with a full display of the charging process and battery capacity.
Operation
After installing the battery pack onto the charging socket, the RP-DC50 measures the internal
battery cell resistance and starts pre-charging.
• Please check that the DV Battery pack is compatible with RP-DC50 power voltage and current.
• Be sure that the battery charger plate firmly locks the battery in place.
• Observe the Charger LCD Monitor.
• If the battery is attached appropriately, it will illuminate the battery channel and current capacity.
• Please use the manual instructions of the battery pack that you want to charge.
• Read that manual carefully before using the battery with this RP-DC50 Battery Charger.
• We are not responsible for any damage caused by incorrect use or operation.
• Dual Digital LCD Battery Charger RP-DC50 has two charging modes: NORMAL and BOOST.
• When you turn ON the charger, the default charging mode is NORMAL.
• If you want to charge two (2) batteries simultaneously in a normal mod, the charger will provide
a charging power of 500mA per one charger slot.
• If you want to speed up the charging process and time, you can activate the BOOST mode.
Pressing the RED button on the top of the charger (On LCD, the boost ICON is displayed) will
provide 800mA per one battery slot.
• Charging two (2) batteries simultaneously in a fast charging mode (Boost) charger will give
a current of 800mA per channel.

USB
• You can use your Dual Digital Battery Charger RP-DC50 to power USB devices while charging
your DV Battery. Plug the USB-A cable of your device to the USB-A port of the RP-DC50 charger.
The USB sign on the LCD will pop up. USB is active in both charging modes, the boost and regular.
Exchangeable battery charger plate
• The RP-DC50 digital dual charger can be used for all World brand battery models with easily
interchangeable battery plates. This economical option allows you to charge many different
batteries, all with one charger and a compatible model of battery charger plate.
• The charger automatically sets the charging voltage and current for the designed battery pack.
That leaves no space for charging errors!
• The corresponding battery charger plate that fits the battery you want to charge can be found in
the link: https://www.hedbox.com/finder/
NOTE:
The exchangeable battery charger plates need to be purchased separately.
