2. MAIN MEMORY
A memory bank is available for setting and storing pertinent information for up to 40 different battery
types. Batteries currently in the TrakPower, Onyx
™ and Hobbico ® LiFeSource ™ brands are pre-
programmed into the main memory for easy recall. Refer to the “Battery Memory – Factory Settings”
chart on the fold-out section included with this manual for the default settings in each memory.
A. Selecting a Battery from Memory: Rotate the jog dial to the memory icon (shown above right)
and press to enter. Use the jog dial to scroll until the desired memory is displayed at the top
half of the screen. Press the jog dial once to confi rm the change of memory model. Use the ESC
key to back out to the main menu.
B. Copy Models: If you wish to copy one memory to another, rotate the jog dial to the desired
memory to be copied and press the jog dial. Rotate the jog dial to the desired destination
location and press and hold the dial. A confi rmation will appear asking “Sure?” Press the dial
again to confi rm the copy process. If the memory has been
copied successfully a chime will sound and both displayed
memories will be identical. Use the ESC key to exit to the main
menu. It is not required to use any of the VR-1 memories. In such
case, read further to learn more about manually setting these
parameters for each use.
C. Changing Model Memory Parameters: To change parameters for a particular model number
to match that of your battery needs, rotate and press the jog dial once on the memory icon. In
the “Memory Select” screen, use the jog dial to locate the model number you wish to change
parameters. Press and confi rm with the jog dial. Use the ESC key to back out to the main menu.
With the memory icon selected, press the > key to enter the parameter setup. Use the jog dial
to switch between parameters to be adjusted. Pressing the jog dial will highlight the parameter
and rotating will change it. Once the parameters match that of your battery needs, pressing the
jog dial will confi rm these settings. Use the ESC button to back out to the main menu.
To change the model memory name, follow the instructions as posted for changing the user
name found in the Confi guration section found on page 6.
D. Reset Model Memory: To reset all of the battery models back to factory defaults, follow these steps:
i.
Connect the charger to DC power.
ii. Press and hold the > button and turn on the DC power source. “LCB Port Test” will appear
on the VR-1 charger.
iii. Press the > button once again and the initialization will begin. Once the initialization is
completed, the charger will reset itself.
3. CHARGE
Used to set charge currents, charge voltage, cutoff temperature and maximum capacity. To enter
charge setup, use the jog dial to locate the charge icon as shown to the right and press the > key.
A. Charge Current: To manually adjust charge current, press the dial, then rotate to fi nd the new
charge current ranging from 0.1A (100mA) to 20.0 amps. Re-press the dial to confi rm setting.
WARNING!! It is NOT RECOMMENDED to charge Li-Ion, LiPo or LiFe cells at a greater rate
than their 1C value!! Supplying too much current to a lithium battery can cause very serious
damage (including fi re!) to the batteries and the surrounding area!
B. Charge Voltage (lithium batteries only): Normally, a LiPo battery is charged to 4.2V per cell
but for storage purposes, it can be charged from 3.7V/cell to 4.0V/cell. For charging range per
battery type, please refer to your battery’s instruction sheet. Normal maximum charge voltage
settings for battery types:
LiFe: 3.6V/cell, Li-Ion: 4.1V/cell, LiPo: 4.2V/cell. For higher cycle life time, use 0.1V less. For
storage use 0.4 to 0.5V less. Please refer to page 20 for storage recommendations.
NEVER set output voltage to anything greater than the batteries’ nominal voltage rating.
C. Peak Sensitivity (NiCd and NiMH batteries only): This value determines the sensitivity/accuracy
of the peak detection circuit. Adjustment of this value can help match the characteristics of
your battery to the charges for better peak charges. For NiCd batteries the range is 5-25mV. For
NiMH batteries the range is 1-15mV. A “ZEROpk” – or “Zero volt Delta Peak” – setting is also
available for NiMHs which means it will try to detect the exact voltage peak, but the battery’s
condition must be good and charge currents and voltages must be very clean and stable for
