1. FEATURES
High Power Charging Circuit
The Venom Pro2 charger features a powerful
50-Watt charging circuit. The charger can safely
charge or discharge up to 15 cells of NiMH or
NiCd batteries and up to 6S LiPO batteries.
Optimized Operating Software
When charging or discharging, the Venom Pro2
charger features an “AUTO” function that will set
the output charging current automatically. This
feature is especially useful for Lithium Polymer
( LiPO ) batteries to reduce the possibility of
overcharging or discharging your batteries.
Integrated Inputs
The charger features easily accessible inputs on
the sides of the charger for receiver, transmitter
and igniter outputs, and balance blocks.

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 specications 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
congure 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 dened 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.
