Introduction Congratulations on your choice of the RDX2 Mini charger from Hitec RCD. The RDX2 Mini is a highperformance, microprocessor-controlled charger with battery management capabilities that are suitable for use with most popular battery types. The RDX2 Mini also features integrated balancing for two-four cell, Lithium-Polymer (LiPo), Lithium-Ferrite (LiFe) and Lithium-Ion (Li-Ion), as well as the latest high voltage Lithium-Polymer (LiHV) batteries.
Warning and Safety Notes Warning 4 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. A A A The allowable AC input voltage is 100-240V AC. A This charger and the battery should be put on a heat-resistant, non-flammable and nonconductive surface. A Never place a charger on a car seat, carpet or similar surface. Keep all flammable, volatile materials away from the operating area.
Warning and Safety Notes Continued 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? Have you checked the battery voltage? Lithium battery packs can be wired in parallel and/or in series, i.e. a 2-cell pack can be 3.7V (in parallel) or 7.4V (in series).
Warning and Safety Notes Continued 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.

Specifications | Features Continued Internal Independent Lithium Battery Balancer: The RDX2 Mini employs an individual-cell-voltage balancer. It is not necessary to connect an external balancer for balance charging. Adaptable to Various Types of Lithium Batteries: The RDX2 Mini will charge a variety of Lithium batteries such as Li-Ion, LiPo, LiFe and the new higher voltage LiHV batteries.
Charger Connections 1.) Connecting to Power Source: The RDX2 Mini is an AC charger only. Please insert the AC power cord to the wall socket (100-240V) directly to power it on. 2.) Connecting the Battery: NOTE: Before connecting any battery, it is absolutely essential to check one last time that the parameters were set correctly. If the settings are incorrect, the battery may be damaged and, in worse case scenarios, could even burst into flames or explode.

Charger Operations Initial Setup of the Charger: After connecting the battery, you are now ready to setup the charger to charge your specific type of battery. When the charger is first powered on, you will enter the BATT/PROGRAM by default. Select the type of chemistry cells you want to charge and hit the start button. Change the settings to match the voltage and charge rates for the battery you are charging based on the following instructions.
Charger Operations Continued Warning BEFORE YOU BEGIN CHARGING YOUR BATTERY, MAKE SURE YOU HAVE READ AND UNDERSTAND ALL OF THE WARNINGS AND SAFETY INFORMATION CONTAINED ON PAGES 3-8. DURING CHARGING, THE BATTERY SHOULD BE PLACED INSIDE A FIRE PROOF/ RETARDANT BAG AND ON A FIRE PROOF SURFACE, AWAY FROM OTHER COMBUSTIBLE OBJECTS. The following steps describe how to manually setup the RDX2 Mini: Caution ← BATT/PROGRAM LiPo BATT START/ENTER ← LiPo BALANCE 2.0A 11.v (3S) START/ENTER ← LiPo BALANCE 2.

It receives the same quantity of charge (2Ah) if it is charged for 4 hours at 0.5A, or 15 minutes (=1/4 hour) at 8A. ‘C’ - Rating: Capacity is also referred to as the ‘C’ rating.
Commonly Used Terms [cont.] - LiPo: Multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series will have a nominal voltage of 11.1 volts (3 x 3.7). - Lilon: Multiply the total number of cells in the pack by 3.6. A 2-cell Lilon wired in a series will have a nominal voltage of 7.2 volts (2 x 3.6). - LiFe: Multiply the total number of cells in the pack by 3.3V. A 2-cell LiFe wired in a series will have a nominal voltage of 6.6 volts. (2 x 3.3).
