MUST READ
For the vast majority of users (90%+) reading this paragraph should
be sufficient for installation. The unit can be installed by simply
installing it between an input and output battery as depicted. The
unit, by default, shall start charging when the input voltage exceeds
13.6V and switch off when the voltage drops below 13.3V for more
than 120s (adjustable). Going above 13.6V for 5 seconds shall reset
this timer . The default charging profile is 14.4V abs. and 13.6V float -
for sealed lead acid batteries. (x2 for 24V | x3 for 36V | x4 for 48V). this
means that the vast amount off installations can be fitted out off the box
without any adjustments.
If charging is required when your vehicle is stationary you may require
lower than 13.6V input in order to activate. Please read about the
Stationary vehicle engagement mode later in the manual.

functions. Firstly, on unit start up the battery type is
displayed. Secondly, after startup it becomes an input
voltmeter. Thirdly, during custom setting the voltage
scale is used to set the voltage - refer to later.
12) This LED has 3 meanings. Firstly, when on battery
type selection mode this is the LiFePO4 lithium battery
indicator. Secondly, on default mode (most times) this
shows the charger is on fast charge mode. Thirdly, if
flashing, then the unit is in standby and was in fast
charge prior to entering standby.
13-15) These LEDs show the battery charge
progression through its cycle.
15) Flash when in standby.
16-24) Has 3 functions: Firstly, on start up they show the
output voltage. Secondly, if an alarm is present the alarm
shows up. Thirdly, this row is used in the custom setup
procedure to set timing functions, voltages and time
factors. Its general function is as an output voltmeter, in
the event 2 LEDs are on the voltages is between the 2
settings, if the top or bottom red LED is on then the
voltage is outside the parameters off the voltmeter.
16) High voltage, if on solid it is high output voltage, if
flashing it is high input voltage.

leaving the ignition on in this
mode.
How to get the charger to turn on and operate
- ensure the charger is wired up as depicted above
- when engine is running, the alternator should charge the starter battery.
Because the starter battery is connected to the positive input terminal (Pos in) of the Pro Batt Ultra there should
be at least 13.4V+ (x2 for 24V | x3 for 36V | x4 for 48V) at this terminal, when the engine is running. This shall turn the charger on.
The charger, from default, requires a battery voltage on the positive output terminal (Pos out) in order to start charging, so ensure that there is
battery voltage on the Pos out. If so, the charger shall start charging at the default charging profile (sealed lead acid).
To operate the Pro Batt Ultra
refer to page 7 (next page)
for instructions.

Product Information
The Sterling Battery-to-Battery Charger is
a DC to DC charger designed to be put
between a starter battery and an auxiliary /
house / domestic battery. The product’s
advantages are:
5-10+ times faster charging over
i
conventional charging systems (e.g. the
stand alone alternator).
Fool the alternator into working at its
i
maximum ability in order to ensure all its
surplus power is utilized to charge the
auxiliary battery bank to its maximum
capacity without allowing the starter battery
to become discharged.
Allows the correct voltage and charging
i
curve to be selected for you specific
battery chemistry.
Fixes problems associated with vehicles
i
with smart alternators on Euro 5 / 6
engines. It saves your batteries from high
voltage (e.g. Mercedes 15.4V) - gassing
and low voltages (low as 12.2V) - sulfation.
All unwanted side effects to these new
smart alternators.
Fast and easy installation. Simply
i
connect the unit to your starter battery and
your aux battery.
No extra connections to the alternator
i
and no extra wiring for a split charge
system required.
Voltage drops in cabling compensated
i
for.
Several battery-to-battery chargers can
i
be used in parallel for higher output power
or multiple battery banks.
No voltage rises on the alternator or the
i
starter battery. Therefore, no problems with
the engine's management system.
No vehicle warranty issues as the
i
alternator and the main electrical system
remains untouched.

1) Automatic activation (default setting).
The most common mode, used in 99% off
all installations including vehicles with
Regen. braking system. This means that
the unit is voltage sensitive (no ignition
feed required). When the input voltage goes
to 13.6V-19.0V then the unit will simply start
charging. If the voltage drops below 13.3V
the unit shall turn off.
However, if the input voltage exceeds 13.6V
for 5 seconds the regen. braking timer is
prepped and shall become active if the input
voltage drops down to 12.0V-13.3V. This
timer is 120s (default - can be changed) and
allows the charger to continue charging at
these lower input voltages. If the voltage
drops below 12.0V the charger goes to sleep
irrespective of the timer. If the input voltage
remains between 12.0V-13.3V for over 120s
the charger also goes to sleep. To wake the
charger, the input voltage needs to rise
above 13.6V - this shall also reset the regen.

2) Automatic activation w/ ignition feed.
Mode 2 is identical to Mode 1. The only
difference is that it requires a live signal on the
ignition AND the aforementioned input
voltages. For example, if you have over 13.6V
on the input terminal with no live feed then the
Pro Batt Ultra shall be in standby. Only once
you apply the ignition feed signal the Pro Batt
shall start charging. The charger turns off
when you turn off your ignition.
This mode is beneficial as it give you more
control over when the charger operates.

3) Ignition Feed, low V w/o timer WARNING
This mode is also an ignition feed mode, with
no regen timer. It can operate with an input of
11.5V continuously (customizable). It does
not adhere to the voltage thresholds like the
two modes above. The unit shall enter sleep if
the voltage drops below 11.5V. It shall
immediately come out of sleep if the voltage
rises above 11.5V. There is no adjustable
timer mode for sleep, the unit simply sleeps
when the ignition is off. This mode is best
suited where you want the unit to turn off the
second you turn the ignition off yet have the
ability to have input voltage flexibility.
WARNING with this setting - flat batteries as
the charger works down to 11.5V!

start charging. Above 13.6V, for 5 seconds,
the regenerative braking timer activates
(120 seconds default).
The charger, in default, requires a battery
voltage on the positive output terminal (Pos
out) in order to start boost (this can be
changed). Ensure that there is battery
voltage on the Pos out. If so, the charger
shall start charging at the default charging
profile (sealed lead acid).
The charger shall continue to operate
normally until the input voltage has
dropped below 13.3V. Between 13.3V and
12.0V the unit shall remain on for 120
seconds and then turn off (provided the
input voltage stays between 12.0V-13.3V).
This is required to complement the
regenerative braking aspect of modern
Euro 5/6+ engines - where the alternator’s
voltage can drop below 13V for a short
period of time. When the alternator’s
voltage rises above 13.6V the 120 second
timer ends (+ reactivates the timer) and the
charger remains charging.

On first start up all LEDs will light up in a sequence.
The fan shall then start running for around 12
seconds. If, after this, 2 red LEDs flash for 8
seconds you may have a calibration issue and the
unit should be returned to Sterling. If 2 solid red
LEDs are on at the top or bottom then you either
have high or low input voltage (respectively) - check
your voltages.
Changing charging profile during startup
After the initial start up an LED on the left panel shall
light up for 10 seconds, this shall indicate the battery
type selected - default is sealed lead acid. This is
your window of opportunity to change the charging
profile. If you have missed the opportunity, you can
wait for the unit to go in to normal operation and
follow the instructions at the bottom of the page or
restart the device.
Hold down both buttons on the front panel (SELECT
and SETUP/ENTER) for 10 seconds. All LEDs on
the left column shall now flash. By using these two
buttons toggle through the various profiles (see
below). The right button is up the column and the left
button takes you down the column. The LED shall
light up demonstrating which profile you have
selected. When the LED has illuminated at your
desired profile simply hold both buttons for a couple
of seconds or simply just leave the charger alone for
30 seconds and it will change. The chosen profile
LED shall then flash. The unit shall then restart and
go through the starting cycle again.
Note - if you can only see LEDs on the right column
the chances are you are in an error mode. This
could be down to: Very low output voltages (<5V),
no output connection, reverse polarity or the device
is not detecting a valid operational mode as the
connector wire is either not connected or the
connection configuration is wrong. Please refer to
previous page.
Left and right meter readings.
During normal operation
Out of range voltage values
If voltage exceeds the meter’s range the upper right
LED shall flash. If the voltage falls short of the
meter’s range the lower LED shall flash. If two
neighbouring LEDs, on the voltmeter, are on
simultaneously then the real voltage is between
these two parameters. Example, if LEDs at 14.6V
and 14.2V were on then the approximate voltage
shall be ~14.4V.
Low or high output voltages
If the output voltage is below 5V (10V at 24V) or
reverse polarity then the low output voltage LED will
flash (number 23). Similarly, if the output voltage is
above 15.5V (31.0V at 24V) the high voltage LED
shall flash (number 16). To resurrect these
problems, bring the voltage above 6V on the output
and below 15.5V, correct the polarity and then
restart the device.
Changing charging profile during operation.
While the unit is running, simply hold down the
SETUP and SELECT buttons for 12-15 seconds
and let go. The LEDs on the left column shall light
up. The procedure hereafter is the same as above.
After unit has gone through its startup sequence the
LEDs displayed should be the input voltage on the
left column and the output voltage on the right
column. Also, the top left LED (number 12) should
be on solid which is the fast charge (bulk) LED.

The default auto Regen time is 120 sec. = 2 min.
The timer is prepped at 13.6V-19.0V on the input.
If the input voltage then falls below 13.3V (x2 for 24V)
the auto regen timer starts to count. If the voltage does
not rise above 13.6V the timer will not reset and the unit
will switch off, however, as soon as the voltage rises
above 13.6V the auto regen timer will automatically reset
to the set value (default = 120sec).
To deactivate the auto regen mode set the auto regen time
to 0 seconds.
By pressing the Setup / Enter only button for more than 10
seconds you will enter the Auto Regen Time Setup. During
the whole Auto Regen Setup the “Absorption” LED will
flash.
1. Absorption LED flashing and actual saved auto Regen
time will be displayed on the right bar. Use the 0 to 840
scale. If the unit is out of the factory the 120 (default)
should be displayed.
2. Press right button to increase or left button to decrease
value.
3. To deactivate the auto regen function set timer value to
0. When happy with your choice either wait 30 seconds or
press both buttons at the same time for 2 seconds.
4. Absorption LED, AGM II and Auto Mode LEDs will flash
10 times to confirm value saving.
5. Unit will restart with new Auto Regen time as default and
will remain there until changed again.
Important: If you have changed the cutoff voltage
remember that the auto regen counter reset functions
must see 0.3V on top of the new cutoff voltage.
I.e. You set the new cut off voltage at 14.0V. To reset
the Auto Regen timer the voltage must rise above
14.3V.
SVEM - Stationary Vehicle Engage Mode.
If your usage pattern is mostly stationary, e.g. You are at
the side of the road and you start the vehicle just to run an
inverter - the problem is that the vehicle’s alternator may
only be at 13.3V (and not give a high voltage boost) and
stay there, in this case the Pro Batt Ultra would not engage
as it needs greater than 13.6V to start. The ideal solution
is to have fitted the ignition feed mode (as per explained in
these instructions). However, if the auto mode was used
and the ignition feed had not been installed then you could
use the Stationary vehicle engagement mode.
This mode allows the product to engage at a much lower
voltage (13.1V) and disengage below (13.0V). To select
this mode: Press SELECT button for 15+ seconds and let
go, No Fault LEDs should be on solid and the Regen timer
LED should be solid. To remove this setting then do the
same again.
Warning: setting is the Stationary Vehicle Engage Mode
operating the unit at voltages which may cause problems
in the winter to the starting of the vehicle - please bear this
in mind we do not have enough history with this setting to
make any guarantees that it shall complement winter
conditions - as low voltages could cause vehicle starting
problems.

CUSTOM BATTERY TYPE SETTING (for expert
use only - not required for general operation)
Before proceeding with this, please read and
understand all instructions as it is quite complex and
could take more than one attempt. There are timed
intervals of 30 seconds per setting so it is very
important to know exactly what you require before
starting. If any errors are made simply wait a few
minutes and you can start the cycle again. The
settings offered for adjustment in sequence:
A) Boost / absorption voltage (high voltage charge).
B) Conditioning voltage (medium charge rate
normally between boost and float voltage).
C) Float voltage (no longer charging, this will
provide voltage at a reduced level to maintain the
batteries and provide power for any loads applied).
D) Absorption time factor adjust. The length of time
spent in absorption can be adjusted by a factor 0-16.
This may be beneficial for different battery
chemistries. Gel, for example, tends to absorb
current at a low rate, thus, increasing the length of
time spent in absorption may be beneficial (set
nearer 16). AGM, the reverse (set nearer 0). If in any
doubt, ask your battery retailer or simply use one of
our preset values. To calculate the absorption time
from the time factor simply multiply the factor
number (0-16) by 60 and this give you the time in
minutes. E.g. set to 0 and the absorption time shall
be 0 x 60 = 0 minutes. Therefore, the unit shall go
direct from bulk to conditioning (no absorption).
Alternatively, set the factor to 10. This equates to 10
x 60 = 600 minutes etc... The maximum time the unit
can stay in absorption is 24 hours 1440 minutes.
E) Minimum and maximum absorption times.
Here you can set the maximum and minimum time
the unit stays in absorption. For example, you may
have AGM that may need a maximum of one hour,
or GEL which could require a minimum of 720
minutes (12 hours).
We recommend that you write down your required
voltages and times in the space below. This is so
you know what to programme during setup.

Why use Absorption Time Factor (ATF)?
ATF is simply a number (0-18) that can be used to
multiply by the length of time the charger takes to
reach the bulk/boost voltage from start. For example,
if the bulk voltage is reached in 10 minutes with the
ATF at 4, then 10mins x (ATF 4) = 40 mins of
absorption.

Modifying input on / off voltage thresholds.
The default input voltage thresholds to operate the Pro
Batt Ultra are as follows:
Activation voltage 13.3V-13.6V - the charger turns on
and charges. If the input voltage drops below 13.3V the
charger stop charging instantly. If the input voltage then
goes back to 13.3-13.6V the charger shall charge again.
13.6V+ - the charger turns on and charges. In addition, the
low voltage timer for regenerative braking activates. So,
now, if the input voltage drops to between 12.0V - Timer
activation V13.3V the default 120 second timer shall begin
and the charging shall continue for 120 seconds. To then
reset this timer the input voltage has to go above 13.6V+
again. If the input voltage only goes to 13.3V-13.6V the
charger shall start charging but shall not reset the timer. If
12.0V - 13.3V is maintained for longer than 120 seconds
the charger turns off.
12.0V - 13.3V - this is the regen. braking operational
window - only activated when the default 120 second timer
has been activated (input voltage at 13.6V+). Provided the
input voltage remains between 12.0V - 13.3V for over 120
seconds the unit shall stop charging.
Low voltage trip V<12V - below 12.0V shall result in the
charger turning off immediately - unless in operation mode
3.
11.5V - Low voltage cut off, applicable only when in
operational mode 3. The
Charging voltage 13.6V
13.3VCutoff voltage
Lower voltage trip 12.0V
Low voltage trip (Mode 3) 11.5V
CUSTOM INPUT CUTOFF VOLTAGE
SETTING:
(voltages x 2 for 24V)
Here you can adjust the input voltage
setting that prompts the unit into sleep
mode.
This unit has 3 different cut off preset
voltages. In Auto Mode the cut off
default is 13.3V and in Regen Braking
Mode the cut off default is 12.0V. The
higher figure (Auto Mode) and lower
figure (Regen Braking) are both pegged
together by a 1.3V gap. As these figures
are pegged, when you change Auto
Mode you change Regen voltage to be
1.3V lower.
We have designed it, therefore, so you
can only tune the higher voltage (Auto),
this, then changes the lower voltage,
respectively (by 1.3V). The 3rd cut off
voltage is only relevant when in mode 3,
the low voltage trip is pegged at 1.8V
lower than the Auto Mode voltage.
For example, if you want the Regen
cutoff voltage to be 11.7V - set the
higher voltage to 13.0V (11.7V+1.3V).
The low voltage trip (if in mode 3) is then
11.2V.
Adjustment of operational voltages.
The 4 main control voltages below are inextricably linked.
The voltages can only be adjusted as a block (not
individually). For example, if you wish to reduce the Cutoff
voltage by 0.2V then all other voltages in the block shall
reduce by 0.2V.

regen braking timer
All 4 voltages are always
linked. This block can be
adjusted by changing the
Cutoff voltage value up and
down. This subsequently
changes the other three
voltages by the same value.
Charging voltage (default 13.6V) (always 0.3V above
Cutoff voltage): At this voltage the charger starts
charging. After 5 seconds above 13.6V the regen braking
timer is set. If the input voltage drops to 12.0V - 13.3V this
timer begins. Timer reset when input voltage is 13.6V+.
Cutoff voltage (default 13.3V): This voltage is only
relevant after the charging voltage has been met and the
charger is charging. When the input voltage drops below
this cutoff voltage the charger stops charging and shall
eventually go to sleep. If the input voltage remains
between 13.3V-13.6V the charger shall continue charging.
The Cutoff voltage is the parameter that the user
changes. Cutoff voltageAs noted, by adjusting the you
change the other three voltages mentioned by the same
amount.
Lower voltage trip (default 12.0V) (always 1.3V below
Cutoff voltage): When the input voltage drops below the
Lower voltage trip the charger turns off. The 12.0V
threshold is only relevant if the is regen braking timer
activated. If not, then the low voltage trip is 13.3V. If in
mode 3, the low voltage trip is 11.5V.
Low voltage trip (default 11.5V) (Mode 3) (always 1.8V
below : Only when in operation mode 3 Cutoff voltage)
does the Pro Batt Ultra work down as low at this voltage.

Fault Finding | Troubleshooting
In the event that you feel there is a problem ( ie you aux battery is not charging ) you need to establish 2
things.
is the battery not charging because there is no charge or because its broken.
first check the voltage at the aux battery with the engine running for at least 2 mins, if you are getting 14-14.8
v then the unit is supplying the correct voltage to charge the batter, so if you getting say 14.4 v at the engine
battery and the battery does not seam to be charger then the simple fact is the battery is either full or scrap,
there is really no other answer to this, .
Assumming you voltage at the nattery is way down say 12 . 2 volts ( with the engine on ) then you need to
check the Battery to Battery charger
To help you with this the unit has a built in a feature to help you , after start up the 2 rows off leds turn into 2
volt meters , for the 60 amp and larger models the left hand side off the LEDS is the voltage in and the right
hand side is the voltage out , for the thirty amp version the top leds are the V in and the Bopttom are the V
out, so by a quick loo at the fron pannel you should be able to see the voltage in and the voltage out . If you
want to confirm these readings using a hand held volt meter then always measure the voltage in and out off
the unit AT THE TEREMINALS OFF THE UNIT, at the early stages off product fault finding the products
voltage are important not the battery voltages .
What should you find.
The most important thing is to confirm you have at least 14 volts going into the unit, if you don't have at least
14 v ( on a boat or vehicle ) the unit simply will not work, so if you only have say 12.5 volts with the engine
running ( for a boat or older vehicle then the alternator is simply not working, if you have 0 volts then there is
no connection between the unit and the starter battery so you inline fuse has blown or a wire has dropped off
. If you have a modern van with a euro 6+ engine then you need to wait a few mins as you may be on
regenerative mode and the alternator may be on low voltage mode, however after about 2-3 mins this voltage
should jump up to over 14 v on the vehicle engine.
so bottom line is if the input voltage is to low then the unit will not engege, you actually need a voltage
greater than 13.9 v to first engage the unit.
if the unit has over 13,9 volts ad there are no leds on then the unit is defective ( do just check the neg to
make sure its ok
assumming there is the correct input voltage to start the unit then we can now move to the output , again
check the voltage , all things being well you should be between 14-15 volts out ( this will depend on battery
load and state off charge ) if you are getting 14-15 volts ( the unit looks like it may be working , then check
the voltage at you aux battery, this should be the same voltage as the unit output battery voltage , if its not ie
2 volts lower then you may jave a defective fuse in the line or the wire has dropped off.
Negatives, people always focus on the positive cables and forget the negatives, this unit is designed for a
comm,on negative system, ie the neg from the auxillary system should be well connected to the neg off the
promart/starter battery, in the event off a vehicle do not relie on the cHASSIE AS THAT TENDS TO BE A BAD
NEG, YOU SHOULD RUN A HEAVY CABLE DIRECT TO BOTH NEGS
ALSO MEASURE THE VOLTAGE FROM THE NEG AT THE AUX BATTERY TO THE NEG AT THE
STARTER BATTERY THIS OBVIOUSLY SHOULD BE O-0,5 V if not check you negs
Firstly, ensure the Pro Batt Ultra (BB) is wired up as per
page 7. Ensure negatives are common and the BB
charger’s negative is connected to the starter battery’s
negative - avoid connecting to chassis negative.
Voltages between common negatives should be ~0V.
Secondly, to test the BB, remove (or turn off) any
secondary charging source like AC to DC battery
chargers or solar chargers going to the battery banks.
Leave the primary charger connected (alternator) -
ensure alternator is working. We also recommend
turning off any loads (inverters etc.).
How to test if the Pro Batt Ultra (BB) is charging:
With engine running (alternator charging), what is the
voltage on the input terminal of the BB? What is the
voltage on the output terminal of the BB? Measure these
voltages at the BB’s terminals, not at the batteries
terminals.
Even though, by default, the BB can work down at 12.0V
on the input; it still requires over 13.3V+ to turn on and
get going. If you are getting alternator voltage at the
input terminal (~14V) and 14V+ on the output terminal
the chances are your BB is working fine. If little to no
current is passing through the charger at these voltages
then the batteries are either full or they are deceased. If
the output voltage is between 13V-14V (but rising) then
you could have a situation where the output batteries
were very low in charge (or large in capacity) and the
charger shall be charging at maximum current. Provided
the voltage continues rising the BB is charging.
If your output voltage is less than 13V and your input
voltage is healthy, it could be three things:
1) You have a large load on your output bank - turn load
off.
2) The BB has been turned off - hold SETUP/ENTER +
SELECT button for 5 seconds and let go, to turn on
again.
3) The BB is not working.
If your input voltage is less than 13V, it could be
several things:
Automotive: Your alternator’s voltage is at
less than 13V (the alt. is regenerative braking mode -
sometimes expected on modern Euro 5/6+ engines) -
take vehicle for drive and measure alternator’s voltage
and set up the BB to suit these needs. All vehicle
manufactures have their own software / characteristics
for regen. braking.
Automotive or Marine: If your alternator’s
voltage is ~14V then check continuity between the
alternator’s B+ terminal and the starter battery. If you are
getting ~14V on starter battery then check continuity
between starter battery and BB input terminal.
Automotive or Marine: If your alternator’s
voltage is 0-13V (starter battery voltage) then alternator
may have failed. Or, requires increase rpm of engine,
possible belt slip.
Is your output voltage slightly higher or lower than
expected - even with no loads / chargers on?
Check if you have the temperature sensor connected.
If so, no problems leaving it there, it is simply voltage
compensating for when the temperature at the sensor
is lower or higher than the benchmark 20DegC (69F).
If lower, then the voltage shall rise and vice versa. The
further from 20DegC in either direction leads to
proportional increase or decrease in the voltage.
Possible, voltage drop across long cabling / fuse
holder / diode. Use our remote sense connection on
the unit - refer to page 6, yellow wire.
LED 16 flashing red - over voltage on input. This LED
comes on if there is 19V for more than 3 seconds on
the input terminal. Check the voltage at the input.
Possible regulator fault, or alternative charger’s
voltage is too high.
LED 16 solid red - Over voltage output. There is 16V+
for more than 3 seconds on output terminal. Check the
voltage at the output. Turn charger off, if voltage drops
when off and rises again when turned on the possible
charger fault. If 16V+ irrespective of charger being on
then check alternative charging source.
LED 17 flashing red - over temperature. Unit has
become too hot and switches off. Possible defective
fan. Or, high ambient temperature, ensure good
ventilation or the charger’s vents may be blocked
LED 21 flashes yellow - high voltage drop across
output cable. When the battery voltage sensor is
connected the device has detected too high a voltage
drop between the output and the positive terminal of
the battery (>1.5V). Verify that the cable thickness is
sufficient. Possibly the terminals are corroded or bad
connection. Also check if the cable is actually
connected to the battery.
LED 22 solid yellow or flashing - the charger is in 1/2
power. It has either been manually forced into 1/2
power mode or night mode (refer to page 9). Or, the
charger has engaged1/2 power mode itself due to the
device’s temperature (> 85°C). In this case, check the
fan and the ambient temperature. Possibly the
installation is not properly ventilated. Make the
adequate ventilation.
LED 23 solid yellow or flashing - undervoltage. If the
LED flashes, the input voltage is too low. Check the
alternator or the charging source of the starter battery.
If the LED is solid, the output voltage is very low -
output batteries are likely to be defective.
LED 24 flashing red - high battery temperature. The
unit has shut down due to excessive battery
temperature (> 55°C). Either the battery is defective or
the ambient temperature is too high. Provide adequate
ventilation.
