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 1000 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 1000 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 1000 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 TOTHEIR
MINIMUM SAFE VOLTAGE, NO LOWER. DEEP DISCHARGING A LITHIUM CELLWILL DO
PERMANENT DAMAGE. REFERTO THE STANDARD BATTERY PARAMETERS TABLE ON
PAGE 5 OF THIS MANUAL FOR MINIMUM DISCHARGEVOLTAGES.
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 1000 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 1000,
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.

Twin-Channel Charger:
Hitec’s RDX2 1000 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 1000 employs an individual-cell-voltage balancer.
Independent Cell Balancing While Discharging:
During the discharge process, the RDX2 1000 monitors and balances 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 1000 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 cell’s 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.
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 gases forming, causing the pack to pu.
Terminal Voltage Control (TVC):
For experienced users ONLY, the charger’s end voltage can be reset up to 0.05v/cell higher.
CHARGER FEATURES

11
Warning
Default setting is recommended. ONLY change in a controlled environment.
ALWAYS monitor the battery during the charge process.
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 can also be used with LiPo & LiHV packs in conjunction with the
AD350 Discharger to decrease internal resistance for more power in stock racing.
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.
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 Resistance Meter:
The user can check not only the MAIN pack voltage but each individual cell and its resistance as well.
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 12000mAh, 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 OFF
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 240
minutes, so adjust as needed depending on the charge rate and capacity of the pack.
Battery Charge Percentage:
The battery charge percentage is displayed in real time once you are charging.
Power Supply:
With the built in Power Supply function, you can power devices with up to 27V @ 15A.
NOTE: IF THE POWER SUPPLY FUNCTION IS ACTIVATED, CHARGING IS DISABLED.
