What does it do?
This device will take the lower voltage power from the
battery charger and increase its voltage to match the
required charge curves of the other battery bank
chemistries. The output voltage is independent of the
charger’s input voltage this enables a totally different
chemistry profile (or even voltage scale i.e. 12-24V) to
be selected. This gives all the advantages of the multi
chemistry, multi output charger without the huge extra
cost. It can be simply retro fitted to any multi-output
charging system (within the limitations of the product).
Should only be fitted and operated by an individual
competent in electrical installations. If in doubt
please install using a competent electrical installer.
Remove the lid by pressing in carefully with your
thumb and finger, don’t push the tabs much more
than 5mm. Then the lid should slide off.
Set this unit as close to the battery charger as possible in
a cool dry ventilated space. As with most ideal conditions
on a boat, the cool, well ventilated part is a bit of wishful
thinking. With this in mind you may notice that the unit
comes with a heat sink and a cooling fan. This unit can
o
o
fully function in an ambient of 50 C. After about 55-60 C
o
the units performance will diminish down to about 80 C
where it will shut down.
If you have to fit it in a hot engine room then it should be
okay but try to fit it low down on the bulk head as it will be
a little cooler there.

Why do I need the chemistry module?
Most boats or specialised vehicles have multi-battery
bank installations. This type of installation can cause
problems if the battery chemistries in the installation are
very different from each other (e.g. gel and open lead
acid). Sometimes one battery bank may be on a totally
different voltage scale (i.e. you may have a 12V charger
and require 24V for 1 battery bank (or vice versa)). A
typical example of this is a GEL battery bank for your
starter, an Open Lead Acid battery bank for a secondary
/ aux battery system and a 24V lead acid sealed for the
bow thruster. This causes a problem for most multiple
standard output battery chargers as they can only be set
to 1 battery chemistry type and 1 voltage scale. The
traditional formality in this situation would be to set the
charger to the lowest voltage profile of all three banks.
This is problematic as many battery chemistries (GEL,
AGM and lithium) have sensitive / specific charging
profiles, similarly, too low voltage charging reduces the
potential performance of the charger.
Main Battery Charger requirements for this product
to work.
1) The battery charger should be a multi-output charger,
with 2 or more outputs. The charger’s voltage and
current must fall inside the BCM rating. I.e. no more than
60A if the BCM is a 60A model.
2) The charger’s output must be a power pack. I.e. if the
output charge cable is removed and the charger
switched on there should be about 13/14V or 26/28V (
depending on model ) on the actual charger terminal
with no cables connected.
3) If the charger’s output has a reverse polarity
disconnect on the terminal or requires a voltage
feedback to the terminal before activation then the
battery chemistry module will not work. I.e. we need an
active voltage on the charger terminal for our product to
work.
Installation:
Cables
The Positive Cables - carry the full current of the battery
charger and should be rated as such, look at the chart
over the page for recommended positive DC cable
sizes.
Fusing
DC - Fuse selection - as per the diagram, each positive
output from the module or charger to the battery must be
fused. Choose a fuse that is about 20% higher in
amperage rating than the maximum rating of the
charger, and round it up. Remember, this fuse is

and the 230V /110V AC isolated, then, connect the input
positive cable first, then the output positive cable, then
the negative.
Remote sense, because the unit can compensate for
voltage drop in the cable (if required and fitted) it is best to
fit the unit as close as possible to the battery charger.
Setting the Main Battery charger ( not the module ).
The main a/c mulatable output battery charger must be
set to the lowest battery type setting , ie if you want to
charge a gel( 14.4 ) and a open lead acid battery ( 14.8 )
then the main charger must be set at the lowest voltage (
14.4 ) the battery module can only increase the voltage
above the main charger it cannot decrease the main
charger voltage. Failure to do this will prevent the Battery
chemistry unit from working correctly
Battery type selection - this is simple to do, simply
remove the lid exposing the rotary switch (number 16 on
Fig 1). Look closely for the small arrow to indicate what
position it is pointing at. On start up the top blue (number
7 on fig 1) LED will flash x number of times to indicate the
setting. E.g. 4 flashes when unit fires up every time =
position 4 on the switch. If this is not the correct setting
then simply rotate the knob to correct the position. Then
switch the battery charger off ( wait a few minutes ) then
back on again and the flashes will change. Ensure you
have the correct number of flashes for your battery type
(note: the incorrect battery setting for a few minutes will
not cause any damage to your batteries).
The battery type voltages are on the front label of the
product and on the table over leaf.
After selecting the battery type, make sure the voltages
fall into the battery companies range for their battery
requirements. It may be necessary to use a different
battery type to obtain the correct voltages you need for
your battery. Remember, it's the voltages which are more
important than our battery types - we have simply tried to
decipher a quagmire of different companies’
requirements and group them in some sort of order for
the general public to make what sense of them they can.
The voltage requirements of the battery company will
override our recommendations as it is them who are
supporting the battery warranty etc. Adjust to suit their
requirements.
Some basic battery type information
Flooded or open lead acid batteries, where you can
unscrew the lid of the battery and are able to top it up with
water, these are by far the best types for fast charging
and long life (max voltage 14.8V).
Fit the unit, as close as possible (taking into account the
above requirements) to the battery charger.
If you must fit it in an enclosed engine room (i.e. a small
yacht, where the engine room is fully enclosed with
sound proofing all over the place) then fit any equipment
as low as possible. It is best to fit it outside the engine
room near the battery box.
Battery temperature sensor: Simply connect one of
the enclosed temperature sensor to a battery terminal
post (negative) and to the 2 x small terminals marked
battery temperature sensor. Simply insert one wire into
each side, there is no polarity on these wires. Make sure
you do not crush the temp sensor which is a small device
inside the yellow ring terminal, as this will destroy the
processor chip. The output voltage will be reduced in
accordance with manufacturer’s battery charging
temperature curves. In the event of the battery
temperature increasing due to battery failure, if the
o
batteries exceeds 55 C, the unit would trip.
Battery temp trip ( daisy chain ) or BMS trip. This unit
has a circuit which, if opened circuited, the unit will stop
working (connector 1 on the information drawing). The
product comes with a link wire across the two terminals
to neutralise this trip, if you wish to use this circuit to
daisy chain or allow a BMS to trip the unit then remove
the link and add the devices. This can be used to daisy
chain high temp trips (the blue ones). These are
o
normally 60 C temperature trips, as such, they can be
linked in series to any number of batteries. If a battery
o
reaches over 60 C the link is broken - the product trips.
Or, this can be linked to a BMS ( Battery Management
System) for lithium this can break the circuit to trip the
high charged side of the unit.

These trips open circuit the relay. They isolate the charger from the
batteries. They do not automatically reset, they require the user
(you) to manually turn the unit off and on again. To reset these trip
conditions you must shut down the input power to the unit ( i.e.
switch off the main battery charger ). This will kill the processor.
These trips will also automatically reset every time the main power
source / charger is switched off.

3 x Flash = Remote sense voltage compensation maximised (only
relevant if the remote sense cable is used) check output cable
thickness. For safety reasons the remote sense has only the ability
to increase the voltage from the product by 1.5V to compensate for
output cable voltage drop (any more than this the cables could
overheat). The cable is too thin or the run too long. For the module to
fully compensate for the voltage drop, there is no problem as far as
safety is concerned, it shall just in a potential loss of performance.
To fix this, check your cable thickness and length is suitable for the
current used.
Manual / deliberate trip. If you wish to open circuit the BCM
manually, you can, with the remote control (see Remote Control
page ). This shall result in LEDs 7,8,9 (blue, yellow and green)
flashing. This display suggests the BCM has been manually tripped,
this is not a warning nor an error, simply initiated by the user. It results
in the total isolation of the battery charger from the batteries.

Start up and self test procedure.
Once the unit has been correctly installed and the main battery charger is off, there should be no LED on.
Start the battery charger, the start up sequence is:
1) blue ‘power on’ LED at the bottom will illuminate
2) Approx 0.5 seconds later all the LEDs will illuminate to show all LEDs are okay.
3) All LEDs off then the top blue LED will flash x times between 1 and 9 flashes, this shows what setting the
rotary switch is set to for battery profile type.
4) All LEDs off then the fan will ramp up to full speed to show the fan is okay and multi-speed functions are
okay.
5) After fan test the green LED (number 9 on fig 1) will flash 2 times indicating the battery temperature sensor
is connected, and, if there is no flashes (or even the green LED on) then the temperature sensor is not
connected and the unit will default to 20 Deg C (ambient control setting).
6) Unit will proceed to charging mode
Unit starting to charge going through its 5 stage charging cycle as per below graph
If, on start up, nothing happens, then check if the top blue LED is on. If not there is no electric going to the
unit, if so, measure the input and output voltages and see if the output is a larger voltage then the input to
confirm the unit is operating.

its lowest chemistry setting (if
it has one) then all the current
must go direct to a chemistry
