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.

.
10.0V
VERY LOW
With no ignition 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 charging.
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.

Ignition Feed Mode (mode 2).
Apply an ignition feed cable to the ‘Ignition’ terminal on the
connector 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. The BB shall operate down to 10V on the input
side. When ignition is turned off (0-4V) the BB shall turn off
when input voltage drops below 13.0V (x2 for 24V).
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.

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

you must use the ignition feed mode,

Automatic activation (default setting) - no ignition feed required.
This means that the battery to battery
charger operates based on sensing voltages at the input battery connector. No ignition feed.
When the
input voltage exceeds 13.5V-19.0V (x2 for 24V) then the unit will simply start charging. If the voltage drops
below 13.3V the unit shall turn off. With a caveat, read on.
However
, if the input voltage has exceeded 13.5V (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. These parameters can be modified.
Ignition feed mode 1.
Apply an ignition feed cable to the ‘Ignition’ terminal on the connector 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. The BB shall operate down to 10V on the input side. When
ignition is turned off (0-4V) the BB shall turn off ONLY if input voltage drops below 13.0V (x2 for 24V). Therefore,
this ignition mode enables the BB to operate based on the same voltage parameters as ‘Auto Mode’ above.
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.

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. Can be turned off (page 9)
Ignition feed mode 2 (Pure ignition).
This mode is slightly different to mode 1. If, you want the BB to simply be
on/off based purely on ignition then you shall want to use this mode. For example, if the only time you ever want
the BB to work is when you’re driving (ignition live) then this is ideal. It shall not operate based on the DC voltage
at the input terminal. If you have a live ignition the BB shall turn on, when the ignition is off the BB shall stop
charging. Simple on/off. There are no voltage parameters at the DC input terminal that need to be met here,
simply 10V+ (2x for 24V). To put it in this mode, apply an ignition feed cable to the ‘Ignition’ terminal on the
connector block, as above. ALSO, you shall need to turn on ‘pure ignition feed’ mode by holding down SETUP
button for 20 flashes and letting go. The unit shall now ONLY operate when there is a live ignition feed - if the BB
is wired up without an ignition the unit shall simply not function. This shall limit the unit’s flexibility. However, this
mode shall be ideal for those that have solar chargers or auxiliary chargers who wish for the BB to be OFF when
vehicle is parked up. Apply a factory reset if you wish to restore default settings.
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.
With any of these modes selected, the BB may take up to 60 seconds to turn on. This is due to the BB being
asleep, when not in use. This preserves battery life. It brings the quiescent current down to 1mA.

Ignition feed mode 1. This mode
Ignition mode 1 (default when ignition feed is applied)
allows the user to operate the BB based on the
automatic activation voltage parameters, as above, whilst also having control of the BB using the ignition signal.
If your vehicle’s alternator is putting out a voltage below that of 13V (26V for 24V) the live ignition feed signal
shall still operate the BB (10V+). Whereas, in the mode above the BB shall turn off when the voltage drops below
13.0V or may never even turn on if this voltage is never met. This is why we recommend installing an ignition
feed for Euro 6 vehicles. The BB shall turn off only when the input voltage drops below 13.0V AND the ignition
feed switches off. The possible downside of this mode is that the BB shall work even when the ignition feed is not
applied - provided the input voltage is above 13V (x2 for 24V). This may be sub optimal if you wish for your BB to
remain off when the vehicle is parked up and you have alternative charging sources onto your DC system.
However, this mode may be what you wish for precisely that reason. If you want a more classic binary on/off
ignition mode - please see ignition feed mode 2 below.
Mode 1 is default, once live ignition is applied.
