GT POWER V5 User manual

BALANCE CHARGER FOR
NICD/NIMH/LITHIUM/PB BATTERIES
G.T. POWER V5
Thank you for purchasing
G .T. Power V5 Charger.
This is
a rapid charger
with build-in balancer,
computerised with microprocessor and specialised
operating software. Please read this entire operating
manualcompletely and attentively before using.

-Individual cell voltage balancer for lithium batteries inside
G.T. POWER V5 has an individual-cell-voltage balancer built in so it does not need a separate
balancer when charging LiPo batteries.
-Maximum safety
Delta-peak sensitivity. The automatic charge termination program works on the principle of the
Delta-peak voltage detection.
Capacity limit: The charging capacity always calculated by multiple of the charging current and
time.If the charging capacity exceeds the limit the process will be terminated automatically when
you set the maximum value.
Temperature limit (*): The temperature of the battery on charging will raise by its internal
chemical reaction .If you set the limit of temperature the process will be expired forcibly when the
limit has reached.
Processing time limit: You can also restrain the max
imum process time to prevent from any
possible defect.
Input power monitor: To protect the car battery using as input power from being damaged the
voltage of it always monitored . If it drops below the lower limit the process will be ended
automatically.
-High-power and high-performance circuit
V5 employs the circuit that has max
imum output power of 50W.
As a result it can charge up to
14cells of NiCd/NiMH and 5series of LiPo batteries with maximum current of 5.0A.

CHARGE PROGRAMS
Please ensure you choose the correct charge process for the type of battery you will be charging
as each tupe of battery uses a different charge technique.These techniques are built into the
different programs set up on this charger.
Lithium polymer battery program
Please note that this program is only for Lithium-Polymer batteries with a voltage of 3.7V/cell.Do
not try to charge any other type of battery using this program.The charge current Varies according
to the battery capacity,and is usually 1C.The final voltage of charge process is also very important;
it should be 4.2V/cell for the nominal voltage of 3.7v/cell.If the final voltage exceeds 4.2Vcell by
more than 1% during charge at any time the battery will explode.The charge current,nominal voltage
and cell count set on the charge program must always be correct for the battery to be charged.
Select this charge process by choosing LiPo charge from the main menu by pressing the “start/enter”
button.The display should look similar to this:

WARNING:
When charging LiPo battery at balancing mode
Please connect as shown in diagram 1 correctly.
Failure to connect as shown in diagram 2 will damage this charger.
The value on the left of the second line denotes the
charge current and the value on the right of the second
line denoted the voltage and cell count of the battery pack
to be charged.If you need to alter the settings for the
charge press the“Start/Enter”button to make it blink then
change the value with“DEC”or“INC”button.The value
will be stored by pressing“Start/Enter”button.
Once the settings are correct press the“Start/Enter”button
to begin the charge process.The display will now show
similar to the left diagram.If these values are different
press the“Batt type／Stop”button to return to the previous
pressing the“Start/Enter”button.
Top Line:S=Number of cells selected by in the previous
screen
R=Number of cells detected by the charger.
Once you have started the charge process the following
information will display.The chatger will emit a sound
to inform you when the charge process is complete.To
stop the charge process early press the“Batt type/Stop”
button.

Please note that this program is only for NiMH or NiCD batteries associated with R/C model
applications.Do not try to charge any other type of battery using this program.This program simply
charges the battery using the current you set,the charge current ranges from 0.1A to 5A.
Select this charge process by choosing NiMH or NiCD
charge from the main menu by pressing the“Start/Enter”
button.The display should look similar to this.If you need
to alter the charge current press the“Start/Enter”button to
make it blink then change the value with“DEC”or“INC”
button.The value will be stored by pressing the“Start/
Enter” button.
Once the settings are correct press hold the“Start/Enter”
button to begin the charge process.The display will now
show similar to the following.The charger will emit a
sound to inform you when the charge process is complete.
To stop the charge process early press the“Batt type/Stop”
button.
Please note that this program is only for Pb(Pb,Lead-Acid)batteries with a voltage of 2V-12V.Do
not try to charge any other type of battery using this program.pb batteries are completely different
to NiMH and NiCD batteries,they can only deliver relatively low current compared to their capacity
and similar restrictions apply to the charge process.For this reason the charge current for Pb batteries
should be 1/10 of the capacity.Pb bateries must not be charged rapidly,always follow the instructions
supplied by the manufacturer of the battery.
Select this charge process by choosing Pb charge from the
main menu by pressing the“Start/Enter”button.The display
should look similar to this.The charge current is displayed in
the lower left.The nominal voltage is displayed in the lower
right.The charge current ranges from 0.1Ato 5A.The voltage
should match the voltage of the battery to be charged.If you
need to alter the charge current or the voltage press the“Start/
Enter”button to make it blink then change the value with
“DEC”or“INC”button.The value will be stored by pressing
the “Start/Enter”button.
Once the settings are correct press hold the“Start/Enter”
button to begin the charge process.The display will now
show similar to the following.The charger will emit a sound
to inform you when the charge process is complete.To stop
the charge process early press the“Batt type/Stop”button.
