Please read these instructions concerning your safety
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 during operation
and it is therefore very important to keep their ventilation openings
unobstructed.
Moreover, please follow the safety instructions below.
- Protect the equipment from humid environments. Avoid any
contact with water or other fluids. Do not use if any liquid has
been accidentally spilled inside the equipment .Contact
qualified service personnel for inspection or repair
- Clean only by using a dry cloth
- Unplug when not in use and avoid power surges
- Read the supplied instructions thoroughly and keep handy
- Avoid setting up near heat sources such as fire places,
radiators, stoves or other heat generating equipment
- NEVER use without proper grounding
- Protect the AC mains power plug, connector and cord
- If the equipment develops a fault, have it repaired by qualified
service personnel only
- NEVER block the ventilation openings or obstruct cooling fan
air flow
- Use only as instructed by the manufacturer
- Do not remove cover or dismantle the apparatus. No userserviceable parts inside

Introduction
The BLUESHAPE series of intelligent lithium ion battery chargers
has been specifically designed for fast and reliable charging of the
BLUESHAPE V-lock battery range. All charger models are capable
of delivering up to 4.9Amps in constant current mode making them
particularly suitable to users who require a fast turnaround from their
batteries. For the users’ convenience, the external dimensions have
been kept as compact as possible for better portability.
Properties of the CVS8X
- Elegant and robust design. Ideal for indoor use
- Sophisticated electronics for accurately detecting the charging
state
- Simultaneous battery charging, up to 8 channels through the
external battery adapters.
- Charging power optimisation for maximum charging
performance
- Colour LCD display and three-colour LED indicators for
effective and comprehensive individual charge-station
monitoring
- Pre-charge function for protecting heavily discharged cells
against high currents until their voltages rise to a safe level.
- Maximum compactness and space utilisation
- IPCS and CTP Features (see next pages)
- Powerful auxiliary output at 13.8V / 110W through 4-pole XLR
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 milli-amperes to batteries that are heavily discharged. This
same current enables the charger to detect the current battery state.
Once the cells inside the batteries reach a safe level, the full
(maximum) charging current is delivered until the battery reaches
almost 80% state of charge. After this, a constant voltage phase
begins with the charging current decaying slowly until full cut-off.

IPCS and fast charging
V
The BLUESHAPE CVS8X charger features the highest charging
current for a Li-Ion charger in the broadcasting sector.
This results in currently the shortest possible battery charging time.
BLUESHAPE Li-Ion BV battery series allow fast charging due to
several intrinsic features such as pre-charge protection and cell
balancing; avoiding cell damage and life-cycle shortening, as
demonstrated by the life-cycle performances.
Additionally, the CVS8X charger supports and enhances these
features with IPCS, a 2-step Intelligent Pre-Charge System.
Since fast charging can damage cells if not properly applied,
especially with low voltage (discharged) cells, appropriate care must
be taken. The 2-step procedure implemented by IPCS, initially
boosts very low voltage cells to a state where charge can be applied
with a medium-low current without damage, then starts to charge
with a 300mA current for a while. Finally, when the pack reaches a
reasonable voltage state, it speed-up the charge process by going
to full throttle.
The operation implemented by IPCS is only applied if the prevailing
cells-state need it, and normally takes a few minutes, depending on
the state of discharge of the cells.
The operation implemented by IPCS is outlined in the chart below.

CTP: flexibility of operation and charger reliability
V
Due to the high charging currents developed by the CVS8X charger,
heat control is an issue for a travel charger, especially if the travel
charger is used in potentially hot environments such as inside a car
or a van.
To improve the reliability of the device without compromising its
usage flexibility, BLUESHAPE has developed an innovative feature;
CTP (Charger Thermal Protection) that allows the electronics to
work out the best possible charge profiles without causing damage,
even in adverse temperature conditions.
In case of the charger internal temperature reaching a high level,
the charging current is automatically reduced to avoid possible
damage caused by internal overheating. When the charging speed
is reduced, the internal temperature starts to descend. As soon as
the temperature reaches a safe level, normal charging speed is
resumed.
Through indoor usage, CTP features do not normally intervene
(unless the air convection flow path is obstructed or the internal
cooling fan is damaged).
The operation implemented by CTP is outlined in the chart below.

Operating Instructions
This charger can charge up to 8 batteries independently as follows:
- the channels 1-2-3-4 (left and right side of the charger) are
independent. The charge is managed simultaneously within
each channel.
- the additional four channels 5-6-7-8 are paired with the first four
channels in respective order and the charge is handled
sequentially within each pair (1-5, 2-6,3-7,4-8): first available/
first charged
How to proceed:
- Plug the AC power cord provided into the charger AC input
- Plug and switch on the AC mains supply
- Insert a battery inside any one of the four V-plate adapters as
shown (see picture)

Insert in the direction of the arrow
- Observe the LED. In addition, the charge status may be read in
20% steps through the BLUESHAPE battery LED array.
- Leave the battery to charge for the appropriate time (see table
on page 6)
- Remove the battery when the LED becomes steady green as
shown (see picture on next page)
In the case when you want to charge 2 or more batteries, insert the
additional batteries into the available V-plate adapters.

2) Pull out the battery in
the direction of arrow

Please note that:
- If the battery is installed on the same side of the battery on
charge, it will start charging when the first one has finished
charging.
- If the battery is installed on the other side, it will start charging
immediately and independently.
The LEDs will always display the correct status of the charging
process for each battery.
In the case when an accessory is plugged into the accessories XLR,
the charging process will be suspended only on channels 3-4 and 7-
8. The AUX LED will light up and the other battery LEDs will show
'WAITING'. Once the accessory has been unplugged, the charger
will continue the previous charging sequence and from the same
point of interruption.
PLEASE NOTE THAT THE MAXIMUM LOAD THAT CAN BE
CONNECTED TO THE XLR OUTPUT MUST NOT EXCEED 110W.
ADDITIONAL SAFETY NOTES
Chargers and/or batteries may become hot during
10
charging. This is normal. Please consult your
BLUESHAPE dealer if you notice that either a
charger or a battery, become excessively hot during
the charging operation.
Be careful not to block the equipment’s ventilation
outlets.
Never insert any metallic or any other objects inside
the equipment through the ventilation openings or
otherwise.

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.
