Usage and Handling Safety Instructions
BLUESHAPE lithium-ion battery chargers have been designed to
provide a superior performance by managing relatively high currents
during their operation in order to reduce charging time. As may be
expected, the chargers become warm to the touch during operation.
Charge only lithium-ion rechargeable
batteries as specifically designated on your
charger’s label. Other types of batteries may
burst, causing personal injury or damage.
The charger is also equipped with over-
temperature protection. Please consult your
BLUESHAPE dealer if you notice that either a
charger or a battery become excessively hot
during the charging operation.
Keep ventilation openings unobstructed to
allow adequate airflow through the device.
Never insert any metallic or any other objects
inside the equipment through the ventilation
openings or otherwise.

4
 Do not handle charger, including the charger plug and charger
terminals with wet or damp hands.
 Use of an attachment not recommended or sold by the battery-
charger manufacturer may result in a risk of fire, electric shock,
or injury to persons.
 Make sure that the cord is located so that it will not be stepped
on, tripped over, come in contact with sharp edges or moving
parts, or otherwise be subjected to damage or stress. This will
reduce the risk of accidental falls, which could cause injury and
damage to the cord, which could then result in electric shock.
 Do not operate the charger if it has received a sharp blow, been
dropped, or has otherwise been damaged in any way. Take it to
an authorized service technician for an electrical check to deter-
mine if the charger is in good working order.
 Do not disassemble the charger. Take it to an authorized service
technician when service or repair is required. Incorrect reassem-
bly may result in a risk of electric shock or fire.
 Unplug the charger from the electrical outlet before attempting
any maintenance or cleaning to reduce the risk of electric shock.
 Disconnect charger from the power supply when not in use. This
will reduce the risk of electric shock or damage to the charger if
metal items should fall into the opening. It will also help prevent
damage to the charger during a power surge.
 Do not touch the uninsulated portion of output connector or unin-
sulated battery terminal.
 Recharge battery packs only with the charger specified by the
manufacturer. A charger that is suitable for one type of battery
pack may create a risk of fire when used with another battery
pack.
 Keep the cord and charger away from heat to prevent damage
to housing or internal parts.
 Do not allow gasoline, oils, petroleum-based products, etc. to
come in contact with plastic parts. These materials contain
chemicals that can damage, weaken, or destroy plastic

Introduction
The BLUESHAPE CVS4XL intelligent lithium ion battery chargers
have been specifically designed and optimized for fast, safe and
reliable charging of BLUESHAPE batteries. The charging speed
depends on the type of batteries on charge since the charger
communicates and acquires information from the batteries during
operation. The CVS4XL is capable of delivering up to a maximum of 6
Amps in constant current (CC) mode on all four channels
simultaneously. This makes it ideal for fast turnaround, especially
when using higher capacity batteries. However, when charging
smaller batteries, the charger never exceeds currents higher than
0.5C* to avoid overheating and stress to the lithium Ion cells.
Nevertheless, these chargers can also charge 3rd party, non-
communicative batteries but at a fixed rate. A precaution is included
by design in order not to overcharge 3rd party batteries or render them
unsafe.
The CVS4XL features a 3.5” touch display for intuitive and direct
access to charger control and information.
For the users’ convenience, the external dimensions have been kept
as compact as possible for better portability.
*0.5C is equivalent to half the battery Ah capacity
Features of CVS4XL
 3.5” touch display with adjustable backlight.
 Modern, original and robust design. Ideal for regular daily use.
 Sophisticated electronics for accurately detecting the charging
requirements and applying the correct charging rate accordingly.
 Simultaneous charging of 4 batteries at a maximum of 6A each
battery when fan is switched on.
 Switchable fan for selection of ‘FAST’ or ‘SILENT’ charging
modes.
 Pre-charge function for protecting heavily discharged cells
against high currents until their voltages rise to a safe level.

8
 Precise constant current (CC) and constant voltage (CV)
charging algorithms to match the battery programmed charging
voltage.
 Powerful auxiliary output at a nominal 14.5V* through a 4-pole
XLR. The auxiliary output is available if AC is connected or if a
battery with terminal voltage >12.5V is inserted in any channel.
 Fast USB charging at 2A max. current.
 If AC mains is not present or is suddenly cut off, the AUX power
is drawn from the batteries and the equipment operates as a
UPS and continues delivering power.
 If the battery is placed on charge, the AUX power will be derived
from both mains and battery if necessary.
 Data receptacle via USB Micro-B for computer connectivity and
monitoring of BLUESHAPE batteries through BSCVMON free
software, directly downloadable from our website.
 Note: USB Micro-B cable not included with product.
 Data receptacle can also be used for firmware updates if
necessary, contact BLUESHAPE support for more information.
BLUESHAPE Battery Charging and
Performance Features
The electronic circuitry provides a very accurate lithium ion charge
algorithm. Initially, the chargers will only apply a pre-charge current of
a few mA to batteries that are heavily discharged. Once the cells
inside the batteries reach a safe level, the full (maximum) charging
current is delivered at a maximum rate of 6A (but less than 0.5C) until
the batteries reach almost 90% state of charge (SOC).
*The output voltage of the auxiliary output is
dependent on the battery voltage. It can
therefore range between 12.5V up to 17V.

9
This charging rate is only applied when the fan is set to ON. If the fan
is switched to OFF for silent operation, the charging current is
reduced to not exceed 3.5A (but less than 0.5C - see table).
After the constant current (CC) phase is completed, a constant
voltage (CV) phase initiates with the current tapering slowly to 150mA
until full cut-off.

When a device is powered by the AUX port and at least a battery
is installed, the unit operates as an UPS: in case of a sudden AC
power cut, the device remains powered if at least a battery is
installed and its voltage is higher than 12500mV.
Once the device has been unplugged, the charger will continue
the previous charging sequence and from the same point of
interruption.
The AUX port is always available whenever AC is connected or at
least one battery is present and with a voltage greater than
12500mV.
Working with AC Input
When AC is present and no batteries are installed, the power
available on the AUX port depends on the fan state:
 with fan set ON - 14.5V regulated at max 10A
 with fan set OFF - 14.5V regulated at max 8A
Whenever a battery is connected in charge, the max available
power on the AUX port depends on the power of the installed
battery since if the load on AUX exceeds the available current, the
extra power is provided by the battery that in such case is getting
discharged. The maximum current is capped at 8A.
When a battery is in charge and the AUX is powered, please note
that AUX takes priority:
 The available current is shared between the battery on
charge and the load on the AUX port. Therefore, the charging
current is reduced when the AUX is draining power.
 If the AUX port demand is less than the current that is able to
be drawn from the charger then the remaining current will be
used to charge the battery.
 If the AUX port demand greater than the current that is able
to be drawn from the charger then the battery will go into
discharge to supply the rest of the demand.
See the technical specifications table in this manual to understand
the different current handling under different conditions.

15
Working without AC Input
When operating without AC the available power on the AUX port is
limited by the power of the installed batteries. When at least two
batteries are connected on either side of the charger (eg. Bays 1
and 3) the AUX current output is limited to a maximum of 10A.
Else, when batteries are installed only on one side of the charger
(eg Bays 1 and 2) this maximum output is reduced at 8A.
Batteries connected to the same side will be discharged
sequentially up to a bottom limit of 12500mV When this threshold
is reached by the first battery, the load is automatically connected
to the second battery without interruption. When batteries are
connected to opposite sides, they are discharged in parallel.
 Tapping on the power icon will switch off the charger. To
restart the charger power the charger via an AC input or
disconnect and reconnect all battery packs.
 When the charger is operated without an AC input, the main
screen will display an overlay to indicate this. The fan icon is
also replaced by a power icon to be able to shutdown the
charger when not being used as an auxiliary power supply.

Notes Concerning charger usage with
BLUESHAPE battery Packs
It is recommended that the users always have at least another spare
battery readily available.
It is preferable to charge batteries immediately before use.
Some self-discharge would result if the batteries are charged several
weeks in advance of their use. However, this slight loss can be re-
charged at any time without any degradation of battery performance
(no memory effect).
It is recommended to store batteries in a cool and dry place. Charging
should be done at temperatures above 0°C and below 45°C.
Slight heating of the battery is expected to occur during charge.
If for some reason, the pack temperature reaches 60°C, then the
charge activity is suspended.
The pack resumes normal charging once the temperature drops back
to below 50°C. This is a safety feature incorporated in all BLUE-
SHAPE battery packs.
The contents of this operating manual are subject to change without
notice.
