3. WARNINGS AND SAFETY NOTES

• Never leave the charger unsupervised when it is connected to its power supply. If any

malfunction is observed immediately terminate the process and refer to the operation manual.

• Keep the charger away from dust, dampness or rain, heat, or direct sunshine and vibration.

• The circuit of the unit is designed to be powered by a 10-18V DC only.

• This unit and the battery to be charged or discharged should only be set upon a heat resistant, non-ammable and non-conductive surface. Never charge on a car seat, carpet or similar surface. Keep all ammable or volatile materials well away from operating area.

• Be sure to understand the specications of the battery to be charged or discharged. If the

program is set up incorrectly the battery can severely be damaged. Lithium batteries when

improperly charged, can cause permanant damage or re.

• To avoid short-circuits between the charge lead, always connect the charge cable to the unit

ﬁrst and only then to the battery to be charged or discharged. Reverse the sequence when disconnecting.

• Do not attempt to disassemble battery packs.

3. WARNINGS AND SAFETY NOTES

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

congure 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 dened level. Much like the process of charging, when you discharge batteries you must not leave the battery unattended. To avoid the battery becoming deep-discharged, set the nal discharge

voltage correctly. Lithium batteries should not be deep-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.

4. PROGRAM FLOW CHART

667

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

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 conrm 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 nish 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.

5. INITIAL USER PARAMETER SET UP

This shows the trigger voltage for automatic peak

detection of NiMH and NiCd battery. 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

specication 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 battery can be used. You can set the maximum temperature at which the charger should allow 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 being 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 overcharging of the battery if it

proves to be faulty, 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.

667

Use these programs only when charging a lithium battery (Lilo/LiPo/LiFe) with a nominal voltage of 3.3V, 3.6V or 3.7V 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 specications 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.

6. CHARGING A LITHIUM BATTERY

(LILO/LIPO/LIFE) PROGRAM

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 12volt power source

(lead acid battery) in the eld, 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.

The next screen will ask to conrm 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 connected the supplied balance board to the charger and

then connect the balance lead from the battery to the board. 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 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 conrm 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 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.

“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.

667

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 conrm 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 will sit 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 conrm your setting, press the START/ENTER button. To initiate the storage charge, press and hold START/ENTER for 3 seconds, conrm the cell count

selected is the same that the charger is indicating and press and hold START/ENTER for 3 seconds to begin charging.

stop the charging process at any time.

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 conrm cell count, then hold 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 board 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 increase button with the error message on screen to show you 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 board connection at the charger.

667

Use these programs only when charging a NiMH (Nickel-Metal-Hydride)or NiCd (Nickel-Cadmium) battery. To alter the value on the display, press the START/ENTER key. The charge current can now be altered by using the increase/decrease buttons. The value will be saved by pressing Start/Enter key once. To start the process, press

and hold the START/ENTER button for more than 3 seconds.

7.1 CHARGING NICD/NIMH BATTERIES

With NiMH and NiCD packs, you do not have to indicate to the charger how many cells are in the pack. In auto “AUT” mode, simply set your charge current (no more than a 1C rating.), press START/ENTER for 3 seconds and the charge process will begin. In manual “MAN” mode, it will charge

the battery with the charge current you set at the display. Each mode can be switched by pressing increase/decrease

button simultaneously when the current eld is blinking.

The screen will display the current state of charging. To

stop the process, press the Batt type/Stop key once. An

audible sound will indicate you have ended of process.

7.2 DISCHARGING NICD/NIMH BATTERIES

Set discharge current on the left and ﬁnal voltage on the right. The discharge current ranges from 0.1 to 1.0A and the

nal voltage ranges from 0.1 to 25.0V). Refer to your battery’s

speciﬁcations to determine optimal discharge current and

nal voltage. To start the process, press START/ENTER key

for more than 3 seconds.

The screen will display the current state of discharge. You can alter the discharge current by pressing START/ENTER

key during the process. Once you change the current value,

store it by pressing START/ENTER button again. To stop

discharging press Batt type/Stop key once. An audible sound

will indicate the process has ended.

7. NIMH/NICD BATTERY PROGRAM

7.3 CHARGE/DISCHARGE DISCHARGE/CHARGE CYCLE OF NIMH/NICD BATTERIES

Select the sequence based on the current state of the battery.

If the battery is fully charged, use the Discharge/Charge sequence. If the battery needs to be charged, use Charge/ Discharge. Press START/ENTER to conrm the setting, then

choose how many times to cycle the battery (1-5). Press and hold START/ENTER to begin the process.

To stop the process, press the Batt/Stop button once. Change

the discharge or charge current by pressing START/ENTER while charging. An audible sound will indicate when the process has ended.

When the process is completed, use the increase/decrease

buttons to see the amount of capacity that was charged/

discharged. By pressing increase/decrease again, the results of

the next charge cycle will be shown.

This program is for charging Pb (lead-sulfuric acid) batteries with a nominal voltage from 2V to 20V. The optimal charge rate for a Pb battery is 1/10 of the capacity. Pb batteries must NOT be charged rapidly. Always follow the instructions supplied by the battery manufacturer.

When condent you have the correct settings for your Pb battery, press START/ENTER to begin editing the settings. Use the increase/decrease buttons to adjust the value and press

START/ENTER to save the selected value.

8.1 CHARGING PB BATTERIES

Set up the charge current on the left and the nominal voltage of the battery on the right. The charge current ranges from 0.1A to

6.0A and the voltage should be matched with the battery being charged. Start the charge process by pressing the START/ ENTER button for more than 3 seconds.

The screen will display the current state of charging. To stop the

process, press the Batt type/Stop key once. An audible sound

will indicate you have ended of process.

The screen will display the current state of discharge. Alter the discharge current by pressing the START/ENTER button

during charging. Once you have changed the value, save it by pressing START/ENTER again. To stop the process, press the Batt type/Stop key once. An audible sound will indicate you

have ended of process.

Internal resistance testing can be a very valuable tool for battery diagnostics. The data collected from this form of testing is only truly valuable if the internal resistance is

monitored over the life of a pack. To properly test internal resistance, you must connect

both the charge lead and the balance lead to the charger.

To begin, press START/ENTER. The charger will provide the

results in the form of a milli-ohm rating. Press increase to

check the total results of the pack. Press increase again to

view the single cell data.

The Venom Pro2 Charger provides a data storage and load feature for your convenience. This feature can store
