Introduction
Congratulations on purchasing Hitec’s RDX2 Mini AC Dual Balance Charger.
The RDX2 Mini features independent circuits allowing you to charge two
batteries simultaneously, regardless of chemistry or capacity. The sleek,
compact design of this dual balance charger allows easy front-loading
convenience with balancing and XT60 ports readily accessible, while its
powerful 100W charging output and 5A current will make your battery
charging more ecient and eortless. The RDX2 Mini also includes new
AGM and Cold Charge modes, to safely and easily charge conventional
Lead-based (PB) and Absorbed Glass Mat (AGM) batteries in cold
conditions. Although simple to use, the RDX2 Mini does require some basic
knowledge for successful and safe operation. The operating instructions
included here are designed to ensure that you quickly become familiar
with its functions. It is important that you read through the Operating
Instructions, Warning and Safety Notes attentively and in full before
attempting to use your new charger for the rst time. By following the
guidelines and recommendations provided, you are sure to enjoy many
years of R/C fun with your RDX2 Mini charger!
Please BE SURE to read these INSTRUCTIONS, WARNING and SAFETY NOTES
before you use the charger for the rst time. Mishandling batteries and
battery chargers is dangerous, as there is always a risk of batteries catching
re and exploding.
THE CHARGING AND DISCHARGING OF RC HOBBY BATTERIES CAN
BE DANGEROUS. FAILURE TO FOLLOW THESE EXPLICIT WARNINGS
CAN RESULT IN PROPERTY DAMAGE AND/OR LOSS OF LIFE.
ANEVER LEAVE YOUR CHARGER UNATTENDED WHILE IN OPERATION.
ANEVER CHARGE ON OR AROUND COMBUSTIBLE MATERIALS.
ANEVER CHARGE A DAMAGED BATTERY PACK.
Warning
4
ALOW COST, NO-NAME BATTERY PACKS POSE THE MOST DANGER.
WE RECOMMEND YOU ONLY USE BATTERY PACKS THAT ARE SOLD
AND WARRANTIED BY A REPUTABLE COMPANY.
AIT IS HIGHLY RECOMMENDED THAT YOU UTILIZE A SAFETY DEVICE
SUCH AS A STEEL CASE OR LIPO SACK™ WHILE CHARGING LITHIUM
CHEMISTRY BATTERIES.
AIT IS HIGHLY RECOMMENDED THAT YOU KEEP AN OPERABLE “CLASS
A” FIRE EXTINGUISHER IN THE CHARGING AREA.
FAILURE TO FOLLOW THESE WARNINGS CAN BE
CONSIDERED NEGLIGENCE BY THE OPERATOR AND MAY
NEGATE ANY CLAIMS FOR DAMAGES INCURRED.
Hitec RCD USA will not be held responsible for any damages or injuries
that may occur by persons who fail to follow these warnings or who fail
to properly follow the instructions in this manual.
Warning: Be sure to read this section for your own
safety.
Caution: Be sure to read this section to prevent
accidents and damage to your charger.
Tip: This section will help you maximize the perfor-
mance of your charger.
Note: This section will provide more detailed expla-
nations.
These warnings and safety notes are of the utmost importance. You
must follow these instructions for maximum safety. Failure to do so can
damage the charger and the battery and in the worst cases, may cause
a r e .

NEVER LEAVE THE CHARGER UNATTENDED WHILE IT IS
CONNECTED TO ITS POWER SOURCE. IF ANY MALFUNCTION
IS FOUND, TERMINATE THE PROCESS AT ONCE AND REFER
TO THE OPERATION MANUAL.
AThe allowable AC input voltage is 100-240V AC.
AKeep the charger away from dust, damp, rain, heat, direct sunlight
and excessive vibration.
AIf the charger is dropped or suers any type of impact, it should be
inspected by an authorized service station before using it again.
AThis charger and the battery should be put on a heat-resistant, non-
ammable and non-conductive surface.
ANever place a charger on a car seat, carpet or similar surface. Keep all
ammable volatile materials away from the operating area.
AMake sure you know the specications of the battery to be charged
or discharged to ensure it meets the requirements of this charger.
If the program is set up incorrectly, the battery and charger can be
damaged.
AFire or explosion can occur due to overcharging.
ATo avoid a short circuit between the charge lead, always connect the
charge cable to the charger rst, then connect the battery. Reverse
the sequence when disconnecting.
ANever attempt to charge or discharge the following types of
batteries:
Warning
Warning and Safety Notes [cont.]

• A battery tted with an integral charge circuit or a
protection circuit
• A battery pack which consists of dierent types of cells
(including dierent manufacturer’s cells)
• A battery that is already fully charged or just slightly
discharged and non-rechargeable batteries (these pose
an explosion hazard)
• A faulty or damaged battery
• Batteries installed in a device or which are electrically
linked to other components
• Batteries that are not expressly stated by the
manufacturer to be suitable for the currents the charger
delivers during the charge process
PLEASE BEAR IN MIND THE FOLLOWING POINTS BEFORE YOU
COMMENCE CHARGING:
• Did you select the appropriate program suitable for the type of
battery you are charging?
• Did you set up the adequate current for charging or
discharging?
• Have you checked the battery voltage? Lithium battery packs
can be wired in parallel and in series, i.e. a 2-cell pack can be
3.7V (in parallel) or 7.4V (in series).
• Have you checked that all connections are rm and secure?
• Make sure there are no intermittent contacts at any point in
the circuit.

Standard Battery Parameters
WHEN ADJUSTING YOUR RDX2 MINI 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 CAUSETHE 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 RDX2
Mini 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 oering Lithium cells that can be charged
at greater than 1C but this should ALWAYS be veried before
charging a Lithium battery at rates higher than 1C.
Warning
8
Warning and Safety Notes [cont.]
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 Mini to your battery
must be of an acceptable current rating to handle the applied
charge current. For maximum safety and charging eectiveness,
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.
