Radient Duplex Duplex RDNA0397 Owner's manual - page 11
Have you selected the appropriate program suitable for the type of battery you are
charging?
Did you set up the correct 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).
Use a fire-proof LiPo charging bag when charging/discharging Lithium batteries.
Have you checked that all connections are firm and secure? Make sure there are no
intermittent contacts at any point in the circuit.
Charging:
During charge process, a specific amount of electrical energy is fed into the
battery.The charge quantity is calculated by multiplying charge current by charge
time. The maximum permissible charge current varies depending on the battery
type or its performance, and can be found in the information supplied by the battery
manufacturer. Only batteries that are expressly stated to be capable of
quick-charging are allowed to be charged at rates higher than the standard charge
current.
Connect the battery to the correct charger terminal: Red is positive and Black is
negative. Due to the difference between resistance of the cable and connector, the
charger cannot detect the resistance of the battery pack, the essential requirement
for the charger to work properly is that the charge lead should be of adequate
conductor cross-section, and high quality connectors which are normally gold-plated
should be fitted to both ends.
Always refer to the battery manufacturer’s data sheet or manual for the
recommended charging current and charging time. Lithium batteries should be
charged strictly in accordance to the charging instruction provided by the
manufacturer. It is always recommended that you balance charge Lithium batteries
wherever possible and always se a fire-proof LiPo charging bag when
charging/discharging Lithium batteries.
Special attention should be paid to the connection of Lithium batteries.
Do not attempt to disassemble a Lithium battery pack.
Please note that Lithium battery packs can be wired in parallel and in series. In
parallel connection, the battery's capacity is calculated by multiplying single
battery's capacity by the number of cells with the total voltage staying the same. As
a voltage imbalance between the cells may lead to fires or an explosion, we
recommend that ony Lithium batteries wired in series are charged.
Please check the following points before commencing charging:
Voltage balancing and monitoring when discharging batteries
Charging NiCd and NiMH batteries
The 4th cell can be seen with a much lower voltage than
the others so this is the problem cell. The voltage value
will fall to zero if the cell is disconnected.
The processor monitors the voltage of each cell in the battery pack during the
‘storage’ and ‘discharge’ process. To use this feature, the battery’s balance lead
must be connceted to the charger. If the voltage of any cell is abnormal, the Duplex
will show an error message and terminate the program. If there is an abnormal cell in
your battery, press the ‘Increase’ button when you see the error message to view
which cell has the problem.
The processor has detected that one cell’s voltage is too
low.
This program is for charging and discharging the popular
NiCd/NiMH batteries that are so common in R/C model
applications. Simply press the ‘Start/Enter’ button to make
the value blink, then use the Increase or Decrease buttons
to change the parameter value. Press the ‘Start/Enter’ key
to store the value.
This program charges the battery using the current value
you input. In the ‘auto’ state, you should set the charge
current’s upper limit to avoid damaging the battery by
using excessive current. Some batteries with low
resistance and capacity can lead to higher current draw in
the ‘auto’ charging mode. But in the manual mode, it will
charge using the current you set. Press the ‘Increase’ and
‘Decrease’ buttons simultaneously when in the current
field to switch between Auto and Manual modes.
The screen shows the real-time charge status. Pressthe ‘Batt.type/Stop’ key to end
the program. A sound will be emitted to indicate the program has ended.
