3. WARNINGS AND SAFETY NOTES
PRODUO
Pay close attention and verify the capacity and the voltage of the Lithium battery
pack to be charged or discharged. It may be composed of parallel and series
connection mixed. In parallel link, the capacity of the battery pack is multiplied by
the number of cells but the voltage remains the same. Extreme voltage imbalance
can cause a fire or explosion during the charge process. We recommend you
configure the Lithium battery pack in series only.
Discharge
• The typical purpose of discharge is to determine the residual capacity of the
battery, or to lower the voltage of battery to a defined level. Much like the
process of charging, when you discharge batteries you must not leave the battery
unattended. To avoid the battery becoming over discharged, set the final discharge
voltage correctly. Lithium batteries should not be over discharged to lower than
the minimum voltage, as this leads to a rapid loss of capacity or a total failure.
Generally, you do not need to discharge a Lithium battery.
• Some rechargeable batteries are said to have a memory effect. If they are partly
used and recharged before the whole charge is drawn out, they ‘remember’ this and
next time will only use that part of their capacity. NiCd and NiMH batteries are said
to suffer from memory effect. They prefer complete cycles; fully charge, then use
until empty. Do not recharge before storage; allow them to self discharge during
storage. NiMH batteries have less memory effect than NiCd.
• Lithium batteries prefer a partial rather than a full discharge. Frequent full
discharges should be avoided if possible. Instead, charge the battery more often or
use a larger capacity pack.
• A brand-new NiCd battery pack will not reach peak performance until the pack has
been cycled approximately 10 times. The cyclic process of charge and discharge
will optimize the capacity of battery pack.
These warnings and safety notes are VERY important. Please follow the instructions
for maximum safety; misuse can result in damage to the charger and battery. In
extreme cases, improper use can result in bodily injury or property damage.

5. INITIAL USER PARAMETER SET UP
PRODUO
The Charger will use the default values upon being powered up for the first time. The
screen displays the following information in sequence, and the user can change the values
of each parameter.
The Venom Pro Duo charger features two full-featured chargers within a single housing.
To swap between channel 1 and channel 2, press the “CHANNEL” button on the front of
the charger. The two red LED lights on the front face of the charger will indicate whether
the left or right channel is currently selected.
To change the default values, press the Start/
Enter key once. The value to be adjusted will blink
indicating it can be edited. Use the Inc/Dec keys to
adjust the value to the desired setting, then press
the Start/Enter key once to save your changes for
that value.
The screen will show the nominal voltage of the
three types of Lithium batteries; LiFe (3.3V), Lilo
(3.6V), and LiPo (3.7V). It is very important to make
sure you choose the correct type of battery during
set up. Refer to the battery’s owner manual for
reference if needed. Failure to choose the correct
battery type can cause damage to the battery,
charger, and will void all warranties.
The charger will recognize the cell count of
lithium batteries automatically at the beginning
of the charge or discharge cycle and compare it
to the settings selected. If a voltage has been selected that is different from the voltage it
detects, an alarm will sound.
Over discharged batteries MAY be detected as a lower cell count pack. Always confirm
your setting before starting a charge sequence. Using the “CHK TIME” parameter in
your LiPo/Lilo/LiFe settings can allow you to delay detection in an attempt to bring a
dead battery back to life. YOU MUST USE EXTREME CAUTION WHEN DELAYING CELL
DETECTION. A 10 minute delay is suggested for larger mAh packs, but small capacity
batteries may finish charging/discharging before the 10 minute mark which could result
in catastrophic failure of the battery. If there are any doubts on how to use this feature,
please contact Venom directly.

PRODUO
CHARGER
This shows the trigger voltage for automatic peak
detection of NiMH and NiCd batteries. The effective
value ranges from 5 to 20mV per cell. If the trigger
voltage is set higher, there is a danger of overcharging
the battery; if it is set lower, there is a possibility of
premature termination. Please refer the technical
specification of the battery. (NiCd default:12mV, NiMH
default: 7mV)
You can select the function of the 3-pin port on the
left side of the unit. It can be used as a temperature
sensor port selected at this screen. If the port is
assigned as a temp. port, an optional temperature
probe contacting the surface of the battery can be
used. You can set the maximum temperature at which
the charger should allow the battery to reach during
charge. Once a battery reaches this temperature
during charge, the process will be terminated to
protect the battery. This charger does not connect to
your PC.
When performing a charge/discharge or discharge/
charge cycle, your battery can often become warm
after the charge or discharge period. The “waste time”
setting will insert a time delay to occur after each
charge and discharge process to allow the battery
adequate time to cool down before starting the next
process. The value ranges from 1 to 60 minutes.
Every charge is monitored by a safety timer. The
default setting is 120 minutes or 2 hours. Once this
time limit is reached the charger will stop charging
regardless if the charge is complete. This is
programmed to prevent accidental overcharging of the
battery, or if the termination circuit cannot detect the
battery is full. The value for the safety timer should be
long enough to allow a full charge of the battery. When
your charge completes, if the charger says “TIME” in
the upper right corner of the screen, your charge was
terminated due to the safety timer.

This setting allows you to change the maximum capacity that
will be supplied to the battery during charge. If the nominal
pack voltage is not detected and the safety timer does not
expire for any reason, this feature will automatically stop the
process at the selected capacity value.
The Key Beep/Buzzer settings allow you to turn off the individual button “beep” as well as the musical tone that is used
to alert different mode changes.
When connecting the charger to a 12 volt power source
(lead acid battery) in the field, this setting will allow you to
monitor the incoming voltage. Should the voltage drop below
the value selected, the charger will terminate operation to
protect the input battery.
6. CHARGING A LITHIUM BATTERY (LiIO/LiPO/LiFE) PROGRAM
PRODUO
Use these programs only when charging a lithium battery (Lilo/LiPo/LiFe) with a nominal voltage of 3.6V, 3.7V
or 3.3V per cell, respectively. The charge current going into the battery will vary depending on the chemistry
type so it is VERY IMPORTANT that you select the correct type for your battery. The ending voltage of the
charge is also important as it varies for all three types: 4.2V for LiPo, 4.1V for Lilo and 3.6V for LiFe. The charge
current (how many Amps you are putting into the pack) and nominal voltage (Proper voltage for the cell count
of the battery you are charging) must be correct for the battery to be charged. To change these settings, press
the START/ENTER key to make the selected value blink. Using the increase and decrease buttons, set your
desired amperage, then press START/ENTER to save the setting. You will then be asked to select your nominal
voltage/cell count. Again, use the increase/decrease buttons to reach your desired setting and Press the
START/ENTER button to confirm and save.
Now, double check the charge settings. The upper left corner of the
screen should read the specific battery chemistry you are trying to
charge. In the case of the example, LiPo. The value underneath the
chemistry type is the charge current. Check your batteries specifications
for proper charge rating, but with all Venom batteries, we recommend a 1C
charge rate. If your battery is a 5000mAh, your charge current should be
5.0. If using a 2200mAh pack, the charge rate would be 2.2. Simply placing
a decimal point after the first number in your capacity rating will give
the correct 1C charge rating. To further elaborate, a 2C charge rate on a
5000mAh pack would be 10.0.
The information on the right side of the screen will tell you which type of charge you are using and the voltage
and cell count you are attempting to charge. Remember, THIS VALUE MUST BE SET TO PROPERLY CHARGE
YOUR BATTERY.
When you are ready to charge, press and HOLD the START/ENTER button for 3 seconds.

CHARGER
The next screen will ask to confirm the settings after the charger examines
the battery, giving a cell count. The “R:” value shows the number of cells
detected by the charger. The “S:” value shows the number of cells you
selected in the previous menu screen. If the “R:” value does not match
the “S:” value, the charger is seeing a different cell count than you have
selected. If this happens, press the Batt Type/Stop button to check the
number of cells you have selected. If this is correct compared to the battery,
you may have a problem with your battery. If the values are the same, it is
safe to charge at this point. Press and hold START/ENTER to start the Charge
sequence.
When charging, the screen provides useful information like the charge rate,
number of cells being charged, battery voltage and the amount of mAh, or
capacity that the charger has put into the pack being currently charged.
Press Batt type/Stop to stop the charging process at any time.
6.1 CHARGING LITHIUM BATTERIES IN BALANCE MODE
Lithium batteries comprised of more than one cell will need to be balanced occasionally to ensure the best
possible performance. When balancing you MUST connect the balance plug of your battery to the balance
board that should be plugged in to the front of the charger. The red and black positive and negative charge
leads will still need to be connected to the battery. The “balance” lead simply allows the charger to monitor
each individual cell. When “balance” charging, the charger will monitor each individual cell attempting to
bring them all to the same nominal voltage.
Like a standard charge sequence, the value in the lower left corner of the screen is the selected charge
current, in the lower right, the voltage of the pack that will be charged. To change these values, press the
START/ENTER key to cycle through the adjustable settings. Use the increase/decrease buttons to change the
values and use the START/ENTER button to confirm the values are set. When
ready to BALANCE charge, press and hold the START/ENTER button for 3
seconds to start the process.
The next screen will ask to confirm the settings after the charger examines
the battery by giving a cell count. The “R:” value shows the number of cells
detected by the charger. The “S:” value shows the number of cells selected
in the previous menu screen. If the “R:” value does not match the “S:” value,
the charger is seeing a different cell count than what has been selected. If
this happens, press the Batt Type/Stop button to check the number of cells
selected. If this is correct compared to the battery, there may be a problem
with the battery. If the values are the same, it is safe to charge at this point.
Press and hold START/ENTER to start the charge sequence.
When charging, the screen provides useful information like the charge rate,
number of cells being charged, battery voltage and the amount of mAh, or
capacity that the charger has put into the pack being currently charged.
When the balance plug is connected to the charger, you can press the
“increase” button to view the individual cell voltages. Pressing the “increase
button” a second time will return you to the previous screen. Press Batt type/
Stop to stop the charging process at any time.

6.2 “FAST’ CHARGING A LITHIUM BATTERY
When charging a Lithium battery, the charging current will
begin to drop as the battery reaches nominal voltage. By using
the FAST charge option, the reduction of power will not be as
great as it is with a standard charge. The benefit of this is a
reduced charge time. The drawback is that the pack will most
likely not charge to its full capacity.
Like a standard charge sequence, the value in the lower left
corner of the screen is the selected charge current, in the lower
right, the voltage of the pack that will be charged. To change
these values, press the START/ENTER key to cycle through
the adjustable settings. Use the increase/decrease buttons to change the values and use
the START/ENTER button to confirm the values set. When ready to FAST charge, press
and hold the START/ENTER button for 3 seconds to start the process. Note, when FAST
charging, the lower left corner of the screen will show “FAS” and not the selected charge
current.
6.3 “STORAGE” CHARGING A LITHIUM BATTERY
When a lithium battery sits unused, for long periods of time, it is best to give that pack a
STORAGE charge. This will charge the battery to a nominal storage voltage (3.85V for LiPo,
3.75V for Lilo and 3.3V for LiFe per cell). Storage mode will automatically determine if the
battery needs to be charged or discharged to reach this level. The balance plug of the
battery must be plugged into the charger for a proper storage charge to take place. Set the
charge current and the battery voltage/cell count as you would any other charge mode by
pressing the START/ENTER button to select the parameter you
wish to change, and use the INCREASE/DECREASE buttons to
adjust the value. When you wish to confirm your setting, press
the START/ENTER button. To initiate the storage charge, press
and hold START/ENTER for 3 seconds, confirm the cell count
selected is the same that the charger is indicating and press
the START/ENTER button to begin charging.
When charging, the screen provides useful information like the
charge rate, number of cells being charged, battery voltage
and the amount of mAh, or capacity that the charger has put
into the pack being currently charged. Press Batt type/Stop to
stop the charging process at any time.

CHARGER
6.4 DISCHARGING A LITHIUM BATTERY
Use this setting to discharge a Lithium pack. The charge
current and pack voltage are adjustable using the methods
shown previously in the charge and balance instructions. Never
exceed 1C for the discharge rate and never use a final voltage
lower than what is recommended by the battery manufacturer.
The balance plug of the battery must be plugged into the
charger for a proper discharge to take place. Press and hold
the START/ENTER button to confirm cell count, then press the
button again a second time to start the discharge process.
When discharging, the screen provides useful information like
the discharge rate, number of cells being discharged, battery
voltage and the amount of mAh, or capacity that the charger
has removed from the pack being currently discharged. Press Batt type/Stop to stop the
discharging process at any time.
6.5 VOLTAGE BALANCING AND MONITORING DURING THE DISCHARGE
The processor monitors the voltage of individual cells during ‘storage-mode’ and
‘discharge’ of a Lithium battery pack. It tries to regulate the voltages to be equal. For this
feature, the balance plug of the battery pack must be connected to the balance port of the
charger. If the voltage of any one or more cells varies abnormally during the procedure, it
terminates the process with an error message. If this happens, the battery pack contains
a bad cell, or there is a bad connection at the balance plug. You can easily know which
one cell is bad by pressing the increase button with the error message on screen to show
the individual cell voltages. This method of viewing cell voltages can be used during any
lithium battery charge, or discharge process provided the balance lead from the battery is
plugged into the charger.
In this example, the charger found that the voltage of one of the
cells in this 4S pack is too low.
By pressing the “increase” button when the error message is
displayed, we can see that cell #4 is reading 2.18, which is below
the minimum recommended 3.0 per cell. If all cells read 0.00, the
balance lead from the battery may have come disconnected.
Also check your balance port connection at the charger.
