WARNING AND SAFETY NOTES
Charging
During charge process, a specific quantity 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 by the battery manufacturer. Only batteries that are
expressly stated to be capable of quick-charge are allowed to be charged at rates higher
than the standard charge current.
Connect the battery to the terminal of the charger: red is positive and black is negative.
Due to the difference between resistance of cable and connector, the charger can not
detect 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 manual by the battery manufacturer pertaining to charging methods.
Operate according to their recommended charging current and charging time. Lithium
batteries, in particular, should be charged strictly according to the manufacturer’s
instruction.
Close attention should be paid to the connection of Lithium batteries.
Do not attempt to disassemble the battery pack arbitrarily.
Please get highlighted that Lithium battery packs can be wired in parallel and in series. In
the parallel connection, the battery's capacity is calculated by multiplying single the
battery's capacity by the number of cells, bearing in mind that total voltage stays the same.
If the voltage is imbalanced, it may cause a fire or explosion. Lithium batteries are
recommended to charge in series.

WARNING AND SAFETY NOTES
Discharging
The main purpose of discharging is to clean the residual capacity of the battery, or to
reduce the battery' voltage to a defined level. The same attention should be paid to the
discharging process as the charging process. The final discharge voltage should be set up
correctly to avoid deep discharging. Lithium batteries cannot be discharged to lower than
the minimum voltage, or it will cause a rapid loss of capacity or a total failure. Generally,
Lithium batteries don't need to be discharged. Please pay attention to the minimum voltage
of Lithium batteries to protect them.
Some rechargeable batteries have a memory effect. If they are partly used and recharged
before the whole charge is accomplished, they remember this and will only use that part of
their capacity next time. This is a 'memory effect' It is said that NiCd and NiMH batteries
are suffering from memory effect. NiCd has more ‘memory effect’ than NiMH.
Lithium batteries are recommended to be discharged partially rather than fully. Frequent
full discharging should be avoided if possible. Instead, charge the battery more often or
use a battery of larger capacity. Full capacity cannot be reached until it has been subjected
to 10 or more charge cycles. The cyclic process of charge and discharge will optimize the
capacity of battery pack.

The balance wire attached to the battery must be connected to the charger with the black
wire aligned with the negative marking. Take care to maintain correct polarity! (See the
wiring diagram below.)
This diagram shows the correct way to connect your battery to the SKYRC QUATTRO
B6AC while charging in the balance charge program mode only.
WARNING:
Failure to connect as shown in this diagram will damage this charger.
SKYRC QUATTRO B6AC comes with the built in switching power supply. You can connect
the AC power cord directly to the main AC socket. (100-120V AC US Version or 220-240V
AC EU Version) For attaching directly to 12V car batteries. It is critically important that you
use a fully charged 13.8V car battery
Important!!! Before connecting a battery it is absolutely essential to check one last time
that you have set the parameters correctly. If the settings are incorrect, the battery may
be damaged, and could even burst into flames or explode. To avoid short circuits between
the banana plugs, always connect the charge leads to the charger first, and only then to
the battery. Reverse the sequence when disconnecting the pack.

“Start/Enter” key once.
User setup starting screen.
The screen displays the nominal voltage of Lithium battery. There are
three kinds of Lithium battery: LiFe(3.3V), Lilo(3.6V) or LiPo(3.7V).
This is very important so you have to check the battery carefully and
set it up correctly. If it is different from correct value the battery may be
exploded during charge process.
SKYRC QUATTRO B6 recognize the cell count of Lithium battery
automatically at the beginning of charge or discharge process to avoid
from erroneous setting by user. But deeply discharged battery can be
perceived incorrectly. To prevent the error, you can set the time term to
verify the cell count by the processor. Normally, 10 minutes are
enough to perceive the cell count correctly. For the battery of larger
capacity, you may extend the time term. But if you set the time term to
long for the battery of smaller capacity, the charge or discharge
process can be finished within the time term with the erroneous cell
count. This may cause the fatal result. If the processor recognizes the
cell count incorrectly at the beginning of charge or discharge process,
you may extend the time. Otherwise, you had better use with the
default value.

Safe Timer Calculation
For example:
This shows the trigger voltage for automatic charge termination 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 specification of the
battery. (NiCd default: 12mV, NiMH default: 7mV)
An optional feature using temperature probe contacting the surface
of battery, the temperature cut-off can be on or off. If it is on, 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.
The battery becomes warm after cycles of charge/discharge
process. The program will insert a time delay after each charge/
discharge process to allow the battery enough time to cool down
before beginning next cycle of charge/discharge process. The valid
value ranges from 0 to 60 minutes.
When the charge process starts, the integrated safety timer starts to
run simultaneously. If an error is detected or the termination circuit
cannot detect whether the battery is fully charged or not, the unit is
programmed to prevent overcharging. Please refer to the below
statement to calculate the safe timer to be set.
When charging NiCd or NiMH batteries, divide the capacity by current, then divide the
result by 11.9, set this number of minutes as the value for safety timer setting. If the
charger stopped at this time threshold, about 140% of the capacity will have been fed into
the battery.
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes

Lithium battery (LiIon/LiPo/LiFe) program
These programs are only suitable for charging and discharging Lithium batteries with a
nominal voltage of 3.3V, 3.6V and 3.7V per cell. These batteries need to adopt different
charge technique that is termed constant current (CC) and a constant voltage (CV)
method. The charge current varies according to the battery capacity and performance.
The Lithium battery is charged at a
constant current until it reaches the
final charge voltage of 4.2 V per cell
(B). After this point the voltage is
kept at a constant level, and the
residual charge takes the form of a
declining current curve (C) until the
cut-off point (D) is reached. Charge
current = C/10. At this point the
battery can be disconnected from
the charger, and is ready for use.
The final voltage of charge process is also very important; it should be precisely matched
with the charged voltage of the battery. They are 4.2V for LiPo, 4.1V for Lilo, and 3.6V for
LiFe. The charge current and nominal voltage as for cell count set on the charge program
must always be correct for the battery to be charged. When you are willing to alter the
parameter value in the program, press start/enter key to make it blink then change the
value with Inc> or <Dec key. The value will be stored by pressing start/enter key once.

This program charge the battery using the current you set up. In the 'auto' state, you
should set up the upper limit of the charge current to avoid damage by excessive feeding
current. Some batteries of low resistance and capacity can lead to higher current in the
'auto' charging mode. But in the manual mode, it will charge with the current you set. You
can make it blink in the current field and press INC and DEC simultaneously to swap
between Auto and Manual Mode. NOTE: Allowable fast charge current: 1C-2C.
