PLEASE CHECK THE FOLLOWING POINTS BEFORE YOU BEGIN 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 firm and secure?
• Make sure there are no intermittent contacts at any point in the circuit.
Hitec Group USA, Inc. (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.
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.
! The allowable AC input voltage is 100 - 240V AC
! The allowable DC input voltage is 11-18V DC.
! Keep the charger away from dust, damp, rain, heat, direct sunlight and excessive vibration.
! If the charger is dropped or suers any type of impact, it should be inspected by an
authorized service station before using it again.
! This charger and the battery should be put on a heat-resistant, non-flammable and
non-conductive surface.
! Never place a charger on a car seat, carpet or similar surface. Keep all flammable
volatile materials away from the operating area.
! Make sure you know the specifications 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.
! Fire or explosion can occur due to overcharging.
! Never attempt to charge or discharge the following types of batteries:
• A battery fitted 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 non-rechargeable (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.
WARNING
WHEN ADJUSTING YOUR RDX2 800 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.
WARNING
Before charging your batteries, it is critical that you determine the maximum allowable charge rate
for your batteries. The RDX2 800 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 verified 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).
