Standard Battery Parameters
WHEN ADJUSTING YOUR RDX1 PRO CHARGING PARAMETERS, BE
SURE YOU SELECT THE PROPER BATTERY TYPE AND CELL VOLTAGE
FOR THE TYPE OF CELL YOU ARE CHARGING. CHARGING BATTERIES
WITH THE WRONG SETTINGS MAY CAUSE THE CELLS TO BURST, CATCH
FIRE OR EXPLODE.
Charging
Before charging your batteries, it is critical that you determine the maximum
allowable charge rate for your batteries. The RDX1 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 RDX1 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
Warning

7
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 Lithium or Lead-Acid battery packs.
Discharging
The RDX1 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 PAGE 6 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 RDX1
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 RDX1 Pro
discharging to minimum acceptable voltages and performing a balance charge
at 1C maximum rate is 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
Optimized Operating Software
The RDX1 Pro “auto” feature sets the charge and discharge current for you
automatically, preventing overcharging which can damage your battery. In the
event of an error, the RDX1 Pro instantly disconnects the circuit and sounds an
alarm. This feature can be set by the user and controlled through the two-way
link for maximum safety.
Program Select
The charger can store up to 10 dierent charge/discharge proles for your
convenience. You can keep the data pertaining to program settings of the
battery for continuous charging or discharging. Users can call out this data at
any time without setting any additional programming.
Internal Independent Lithium Battery Balancer
The RDX1 Pro features a built-in cell voltage balancer so you don’t need to fuss
with external balancers while charging.
Balancing Individual Cells During Discharging
When used with a balancing board the RDX1 Pro can monitor and balance each
cell in the pack individually while discharging. If the voltage of any single cell is
abnormal, the RDX1 Pro will display an error message and the process will end
automatically.
Adaptable to Various Types of Lithium Batteries
The RDX1 Pro will charge and discharge a variety of Lithium batteries such as
LiIon, LiPo, LiFe and the new higher voltage LiPo, (LiHV) batteries.
Multiple Lithium Battery Charge Modes
The RDX1 Pro features four methods of charging: Regular charge, Fast charge,
Balance charge and Storage charge modes. We highly recommend using
balance charge as it is the safest and best way to charge lithium chemistry
batteries. If you plan on not using your Lithium chemistry batteries for an
extended period of time, Storage charge mode is recommended to optimize
your packs for long term storage and maximum lifespan.

11
Input Power Monitoring
The RDX1 Pro input voltage is monitored to protect the battery from becoming
damaged. The process ends automatically if it drops below the limit.
Capacity and Temperature Limits
The charge process will terminate if either the charging capacity or battery
temperature exceeds the limit set by the user. The temperature function
requires an optional temperature probe, which is not included with the
RDX1 Pro.
Processing Time Limit
Protect your battery by setting a maximum time limit for charging and
discharging.
Cyclic Charging/Discharging
A battery can be cycled 1 to 5 times consecutively. This process is good for
refreshing and balancing your battery.
Maximum Safety
Our delta-peak voltage detection program ends the charge cycle whenever a
battery’s voltage exceeds the set threshold.
Automatic Charging Current Limit
Charging current can be set by the user when charging Lithium, NiCd or NiMH
batteries. The ‘AUTO’ charging mode, however, is recommended when charging
NiMH batteries with low impedance and capacity.
LiPo Battery Meter
The user can check the battery’s total voltage, the highest and lowest as well as
each cells voltage.
PC Control Using Charge Master Software
The free Charge Master software gives you unparalleled ability to operate the
charger through the computer. You can monitor pack voltage, cell voltage and
other data during the operation. Additionally, you have the ability to set up the
charger and update the rmware.
