The IMP003 Imperium 5A DC-DC charger converts
direct current into the correct charging voltage for
the onboard battery.
The Imperium 5A DC-DC charger will limit the
charging current to a maximum of 3.1A to avoid
overloading the cabling and it also ensures that no
current can flow from the on-board battery back to
the starter battery, as with all LiFePO4 batteries it is
better not to have a direct connection to any other
type of battery. Because the offered charging
voltage is often too low to fully charge LiFePO4
(14.6V) batteries, the DC-DC 5A charger transforms
this charging voltage to the correct voltage.
When the charger is setup for lead-acid batteries it
operates a 4 step, 3 stage voltage.
When the charger is setup for lead-acid batteries it
operates a 4 step, 3 stage charging profile. When
the charger is setup for lithium batteries it operates
a CC/CV charging strategy

Read this manual carefully before using the
Imperium DC-DC 5Ah Charger;
Keep this manual near the Imperium DC-DC 5Ah
Charger and ma
k
e it available to the user of the
Imperium DC-DC 5Ah Charger;
As soon as the voltage of the source battery is
available the green Power LED of the charger will
turn on. During the charging process the red Charge
LED will be on. When the battery is fully charged the
Charge LED will turn off.
When the incoming voltage will go under 11.2 V or
12.0 V, the charging process stops to prevent the
source battery being discharged too deep
(depending on the settings).
Only tec
hnically qualified pe
rsonnel should install
the Imperium DC-DC 5Ah Charger;
Use cables with the correct cross-section and
k
