Warnings and Safety Notes
Charging
Before charging your batteries, it is critical that you determine the maximum allowable charge rate for
your batteries. The RDX2 Pro is capable of charging at high rates that may not be suitable or safe for your
particular batteries. For example, Lithium cells are typically safe to charge at 1C, or the total mAh÷1000.
A 1200mAh battery would have a 1C charge rate of 1.2 amps. A 4200mAh battery would have a 1C charge
rate of 4.2 amps. Some manufacturers are o ering Lithium cells that can be charged at greater than 1C but
this should ALWAYS be veri ed before charging a Lithium battery at rates higher than 1C. Voltage is just
as critical as the charging amperage rate and this is determined by the number of cells in series, or “S”. For
example, a 3S LiPo is rated at 11.1 volts (“S” multiplied by a single LiPo cell with a nominal voltage of 3.7
volts DC. 3 cells x 3.7 volts each equals 11.1 volts DC).
Connect the battery’s main leads to the charger output: red is positive and black is negative. Keep in
mind that the gauge or thickness of your charging leads from the RDX2 Pro to your battery must be of
an acceptable current rating to handle the applied charge current. For maximum safety and charging
e ectiveness, always match or exceed the main battery lead rating when assembling or selecting your
charging leads. If you charge a battery at a high current rate (amperage) with a charging lead not rated for
the chosen amperage, the wire could get hot, catch re, short out and/or potentially destroy your battery
and the charger. When in doubt, always use a higher gauge wire (lower AWG number). It is common to see
charging leads constructed of 14AWG, 16AWG or 18AWG wire.
Always refer to recommendations from your battery manufacturer for your speci c battery type and size
before initiating a charge or discharge process.
Do not attempt to disassemble or modify ANY battery packs.
Discharging
The RDX2 Pro discharging functions are for two speci c purposes:
• Refreshing the capacity of a Nickel-based battery that has lost capacity over time (NiMH or NiCd).
• Reducing the voltage of a Lithium battery for safe storage.
LITHIUM CHEMISTRY BATTERY PACKS SHOULD ONLY BE DISCHARGED TO THEIR
MINIMUM SAFE VOLTAGE, NO LOWER. DEEP DISCHARGING A LITHIUM CELL WILL DO
PERMANENT DAMAGE. REFER TO THE STANDARD BATTERY PARAMETERS TABLE ON
Warning
PAGE 5 OF THIS MANUAL FOR MINIMUM DISCHARGE VOLTAGES.
LiPo & LiHV Charge/Discharge Cycling
Lithium batteries are known to reach full capacity after a break-in period of about 10 charge/discharge
cycles. We do not recommend you use the RDX2 Pro charger to do this; normal use and recharging will
achieve the same results. If you wish to perform a Lithium break-in on the bench with the RDX2 Pro,
discharging to minimum acceptable voltages and performing a balance charge at 1C maximum rate is
6
recommended. If you choose to break in your Lithium batteries under normal use, charging at only 1C for
the rst ten cycles will help ensure full performance and service life from your Lithium cells.

Features
Battery Memory (Data Store/Load):
The RDX2 Pro can store up to 10 di erent charge pro les per por t for your convenience. Users can keep
the data pertaining to any program setting for any battery to facilitate seamless charging or discharging.
Saved pro les can be accessed and recalled, as necessary.
Terminal Voltage Control (TVC):
For experienced users ONLY, the charger’s end voltage can be reset up to 0.05v/cell higher.
Default setting is recommended. ONLY change in a controlled environment.
ALWAYS monitor the battery during the charge process.
Warning
Twin-Channel Charger:
Hitec’s RDX2 Pro allows you to plug two batteries into the charger simultaneously. The batteries being
charged do not need to have the same con guration. You can connect di erent battery chemistries (NiMH/
NiCd/LiPo/LiFe/Lilo/LiHV/Pb) into any of the charging ports.
Internal Independent Lithium Battery Balancer:
The RDX2 Pro employs an individual-cell-voltage balancer. It is not necessary to connect an external
balancer for balance charging.
Independent Cell Balancing While Discharging:
During the discharge process, the RDX2 Pro can monitor and balance each cell of the battery individually. If
the voltage of any single cell reads abnormally, an error message will display and end the process automatically.
Adaptable to Various Types of Lithium Batteries:
The RDX2 Pro will charge a variety of Lithium batteries such as LiPo, LiFe, LiIo and the new higher
voltage LiHV batteries.
Multiple Lithium Battery Charge Modes:
Balance Charge:
In this mode, each cell is monitored and if some are at higher voltages than the others, they are
discharged to equalize the voltage between all the cells and keep the pack in optimum condition. We highly
recommend using Balance Charge as it is the safest and best way to charge Lithium batteries.
Charge:
This mode charges the pack without balancing the cells. Connecting the balance lead is still recommended
so you can monitor each cells voltage manually by scrolling to the left with the Jog Dial. Note: If the cells are
more than 0.02v o from each other, Balance Charge should be used to equalize the pack.
Fast Charge:
This mode reduces the charge time by approximately 25% as the charge process stops after the terminal
voltage is reached. This will provide about 85% -90% of the rated capacity.
Storage:
This mode charges or discharges the pack to 50% capacity so that it can be safely stored when not in
normal use. If you do NOT plan on using your Lithium pack within 24-48 hours of being fully charged or fully
discharged, Storage Mode is recommended to optimize maximum lifespan and performance and reduce the
risk of the gasses forming, causing the pack to pu .

Features
Re-Peak Mode of NiMH/NiCd Batteries:
In Re-Peak charge mode, the charger can peak charge the battery once, twice, or three times in a
row automatically. This function is useful for ensuring a full battery charge.
Cyclic Charging / Discharging:
A battery can be cycled 1 to 5 times consecutively. This process is normally used for NiCd or NiMH
packs that have lost capacity over time. It is not recommended for Lithium packs.
NiMH / NiCd Auto Charging:
Charging current is determined by the charger up to the maximum set by the user by evaluating the
internal resistance of the pack so as not to charge at too high of a rate. This mode is recommended
when charging NiMH or NiCd batteries where you are unsure of the optimal rate at which to charge.
Delta-Peak Sensitivity for NiMH/NiCd:
This function determines the amount of voltage drop in MV that must be achieved for the Delta-Peak
algorithm to automatically terminate the charge process. This can be raised for packs that have a
tendency to “False Peak” at the default setting.
Battery Meter:
The user can check not only the MAIN pack voltage, but the highest and lowest voltage is also stored,
as well as each individual cell.
Battery Resistance:
The user can also check the battery’s total internal resistance and the internal resistance of each cell.
This is helpful when determining the health of a pack.
Capacity Cut-O Limit:
This feature allows the user to set a limit for the maximum mAh’s that can be put into the pack. Once
this limit is reached, the charge process will automatically terminate, and “OVER CHARGE CAPACITY
LIMIT” will be displayed. Default is 5000mAh, so set this accordingly to the rated capacity of the
pack. To ensure the pack gets fully charged, this setting should be at least 10% higher than the rated
capacity on the pack or turned to o .
Safety Timer:
Protect your battery by setting a maximum time limit for charging. Once this limit is reached, the
charge process will automatically terminate, and “OVER TIME LIMIT” will be displayed. Default is 120
minutes, so adjust as needed depending on the charge rate and capacity of the pack.
USB Power 5V/2.1A:
You can charge your phone, tablet or any other USB-powered devices using the built-in USB port.
Battery Charge Percentage:
The battery charge percentage is displayed in real time once you are charging. To view, SCROLL to the
left with the Jog Dial to monitor.
Power Supply:
With the built in Power Supply function, you can power devices with up to 25V @130W.
NOTE: IF THE POWER SUPPLY FUNCTION IS ACTIVATED, CHARGING IS DISABLED.

NiMH/NiCd Battery Program
NiMH/NiCd Cycle Mode: The RDX2 Pro makes cycling of NiMH/NiCd batteries easy. The process of
charging, discharging and recharging (cycling) can be performed automatically with one simple step
and will improve the performance of NiMH/NiCd batteries. We strongly recommend cycling any battery
that has been discharged and stored for a long period of time or has lost capacity over time. This will
increase the remaining usable battery life and improve the batteries performance.
Note: Since the Cycle mode uses the Charge and Discharge settings
from those modes, make sure you have them set to correlate with the
Note
batteries you are planning to cycle.
TIP: TAKE NOTE OF THE CAPACITY. ONCE THE NEXT CYCLE BEGINS, IT WILL
DISAPPEAR.
Tip
After selecting the correct battery type, SCROLL to select the
“CYCLE” mode. The Cycle Mode gives you two cycling options:
“DCHG>CHG” or “CHG>DCHG.” The “DCHG>CHG” option

The ‘CHG>DCHG’ option will rst charge the battery and
then discharge the battery. Press the Jog Dial ENTER and this
setting will begin ashing. SCROLL to change this setting to
the option you want.
Press Jog Dial ENTER again and the cycle count begins
ashing. SCROLL to change this to the number of cycles you
want, up to a maximum of 5 times consecutively.
Press and hold the START button for 3 seconds to start the
Cycle Mode.
Once cycling has commenced, the charger will display the
following real-time information: battery type, charging/
discharging current, battery voltage, working mode, elapsed
time and charged/discharged capacity in mAh.
The working mode is displayed as either ‘D>C’ or ‘C>D.’ This
will indicate which cycling order you have chosen. Either ‘D’
or ‘C’ will be ashing. This ashing Indicates which part of the
cycle is currently being executed.
Once the battery is fully charged or discharged, the screen
will read “END: CYCLE” and the charger will emit an audible
“ring” sound. It will also display the Time Elapsed, End Voltage
and Capacity in mAh that was removed. You can press the
