Introduction
The BLUESHAPE CVTR2P 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 CVTR2P is capable of delivering up to a maximum of
6 Amps in constant current (CC) mode on both 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.
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
Properties of the CVTR2P
- Modern, original but robust design. Ideal for regular daily use
- Sophisticated electronics for accurately detecting the charging
requirements and applying the correct charging rate accordingly
- Switchable fan for selection of ‘FAST’ or ‘SILENT’ charging
modes
- Simultaneous charging of 2 batteries at a maximum of 6A each
battery when fan is switched to ‘ON’
- Three-colour LED indicators for individual charge-station
monitoring
- LED for ‘AC on’ indication. No power switch has been provided
- Pre-charge function for protecting heavily discharged cells
against high currents until their voltages rise to a safe level.
- Precise constant current (CC) and constant voltage (CV)
charging algorithms to match the battery programmed charging
voltage.
- Maximum compactness and space utilisation. Extendable,
spring loaded support foot for excellent stability even when
there is just 1 large battery installed. The foot extension is
activated by pressing a push button underneath the charger.
- 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.
- If AC mains is not present or is suddenly cut off, the AUX power
is drawn from the batteries and the equipment operates like a
UPS and continues delivering power.

6
- If the battery is placed on charge, the AUX power will be
derived from both mains and battery if necessary.
- Data connector for computer connectivity and monitoring of
BLUESHAPE batteries through BSCVMON free software,
directly downloadable from our website
Note: The special data cable is not included in the kit but is
available as a separate product.
This socket can also be used for firmware updates if necessary.
*The output voltage of the auxiliary output is
dependent on the battery voltage. It can therefore
range between 12.5V up to 17V
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). 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.

Operating Instructions - CVTR2P
This charger simultaneously charges two batteries with charging
currents of up to 6A, depending on the battery capacity.
How to proceed:
- From underneath the charger, push the centre push button to
extend the foot support. When not in use, or for transport, the
foot support can be pushed back in to lock once again.
- The unit has been designed to remain in balance with just one
battery or with both batteries installed.
- Plug and switch on the AC power cord provided into the
charger AC input (note: there is no power switch in the
charger). The AC mains LED will change from Red to Green
- Insert a battery inside any one of the two V-plates
- Observe the battery LED. In addition, the charge status may be
read in 20% steps through the BLUESHAPE battery LED array
or continuously, using the Wi-Fi features of the battery (see the
battery operating manual for the activation of the internal Wi-Fi
transmitter).
- Leave the battery to charge for the appropriate time (see table
on page 7)
- The battery is fully charged when the LED becomes steady
Green.
You may want to charge 2 batteries at the same time. Just insert the
second battery into the second V-plate adapter. This second battery
will start charging immediately and at the correct rate according to
its capacity. Once again, observe the LED or monitor the battery
status using the Wi-Fi feature.
The LEDs will accurately display the correct status of the charging
process for each battery.
In the case when an accessory is plugged into the auxiliary XLR
port, the charging process may continue but can be slowed down,
depending on the power taken by the AUX port that has the priority.
When an accessory is powered into 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 accessory remains powered if at least a
battery is installed and its voltage is higher than 12500mV.
Once the accessory has been unplugged, the charger will continue
the previous charging sequence and from the same point of
interruption.

AUX port management
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 without AC
When operating without AC the available power on the AUX port is
limited by the power of the installed batteries but up to a controlled
maximum of 8A.
The AUX output is always in parallel with one battery at a time. If
two batteries are connected, they are 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.
Working with AC
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 @ max 6A
- with fan set OFF - 14.5V regulated @ max 4A
On the other hand, 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 @ 8A.
When a battery is in charge and the AUX is powered, it has to be
noted 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 on page 11 to understand the
different current handling under different conditions.

The battery is in charge and is charging at less than
1000mA.
Two possible conditions:
1. The battery is in pre-charge mode because of low
voltage, and is limiting the charging current
2. The load connected to AUX is absorbing current
available and therefore there is not enough power
to charge the battery at full rate. The available
power is shared between charging and AUX
power and the charging current is reduced.

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 loss from self-discharge would result if the batteries are
charged several weeks in advance of their use. However, this slight
loss can be topped up 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.
However 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
BLUESHAPE battery packs.
The contents of this operating manual are subject to change without
