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.

Not obligatory to connect.
If you wish to install, connect the
temp sensor to the negative of
the domestic / aux. batteries.
When temp sensor senses the
temperature lower than 20Deg C
the voltage shall go up on the
charger’s output and when the
temperature is higher than
20Deg C the voltage.
Sensor shall trip the charger if the
temperature of battery >55DegC
compensates for voltage drop across long cables

Pro Batt Ultra starts charging when input is >13.1V.
Turns off when input is <13.0V.
Stationary vehicle engage mode.
Unit on at 13.1V input.
When input below 12.9V, a 20 second
timer starts - if still below 12.9V after the 20
seconds the unit goes to sleep. Requires
13.1V to come on again.
