Fit in a cool dry well ventilated space. Should be
installed by a competent person, conforming
with the laws of the country.
Connect positive
cables (in red) to the terminal block, as shown
below. Similarly, ensure fuses are installed and
negatives are common.

Ensure the charger is wired up as depicted above (larger diagram on previous page). The Pro Batt Ultra shall light

start charging for 120 seconds (1/2 of the regen. braking timer). During the first start up you can change the battery
chemistry profile.
In default mode (1) the Batt Ultra shall simply turn off and goes to sleep after 240 seconds (can be changed) if the
input voltage has not risen above 13.2V.
If you have it set to Ignition Mode, and the ignition is live, then

10.0V
VERY LOW
In default mode the input voltage needs to rise to above 13.2V-19.0V (x2 for 24V) in order for the Batt Ultra to start
charging. This can be achieved by starting your engine. Above 13.2V, for 5 seconds, the regenerative braking timer
activates (120 sec (first time after start/wakeup) then 240 seconds
default
).
There may be a delay of up to 60 seconds before the BB ultra starts.
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 13.2V
the 240 second timer ends (+ reactivates the timer) and the charger remains charging.

Automatic activation (default setting). The
most common mode, used in 50% of all
installations including vehicles with some
EURO 6 / Regen. braking systems
(depending
on application).
This means that the unit is
voltage sensitive (no ignition feed required
unless Euro 6 vehicles are being used in a
stationary application - at idle at the side of
the road).
When the input voltage exceeds
13.2V-19.0V (x2 for 24V) then the unit will simply
start charging. If the voltage drops below 13.0V
the unit shall turn off. With a caveat, read on.
However
, if the input voltage has exceeded
13.2V (2x for 24V) 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 240s (default - can be changed) and
allows the charger to continue charging at these
lower input voltages. If the voltage drops below
11.9V the charger goes to sleep irrespective of
the timer. If the input voltage remains between
11.9V-13.0V for over 240s the charger also goes
to sleep. To wake the charger, the input voltage
needs to rise above 13.2V - this shall also reset
the regen. braking timer.
Ignition Feed Mode.
Apply an ignition feed cable to the ‘Ignition’ terminal on the
connect block.
As soon as there is a signal (> 4V) on this connector, the unit
will wake up (can take up to 60 seconds) and will start to
charge the output battery. The only limit is the input voltage. It
will charge down to 10V on the input side. When ignition is
turned off (0-4V) the BB shall continue charging at ‘mode 1'
charging parameters.
WARNING: If ignition on the vehicle is
left on and the engine is off, you shall deplete your starter
battery down to 10V. Also, if your alternator is less than 60A or
can not produce 60A at idle revs you may discharge your
starter battery.
WARNING: the BB shall start up by
mode 1
voltage
parameters if there is a line feeding the ignition at <4V. We
have done this to allow users to put solar or an AC to DC
charger onto the starter to enable the BB to charge the leisure /
aux battery without running an additional ignition supply.

CHARGE RATE
When engine running, starter battery above 13.3V, then use 1
Euro 6 vehicle (which to choose).
If your usage of the vehicle includes situation applications
where the vehicle engine is being run for long periods at idle
and stationary. I.e. you are simply switching the engine on to
charge the auxiliary battery system
but not driving
, then you
must use the ignition feed mode,
Mode 2.
We appreciate ign. feeds are a hassle (hence it is optional).
Fitting one gives the driver/user more autonomy.
Generally
speaking, if in doubt, fit one!
