The National Luna Power Pack DC25 blends the convenience of a portable battery system and the
performance of a DC-DC battery charger with MPPT solar regulator.
This combination results in a self-contained split-charge system that is at-home in the vehicle or in camp
and can be used to power fridges, lights, pumps and other 12V appliances.
The Power Pack DC25 can be charged from a vehicle alternator, solar panels or external chargers making
it versatile for a variety of applications.
The Power Pack DC25 supports 12V lead-acid (wet, calcium, Gel, AGM) as well as lithium batteries.
The introduction of two dual-port USB modules with fast charge allows several smart devices such as
smart-phones, tablets, GPS, cameras and other USB-devices to be powered up to 18W on each port.
to fridges and other small appliances. These connectors can also be used with external battery chargers
as an alternative to the built-in dedicated charge port.
The primary charge input supports 12V and 24V vehicle systems and will provide up to 25A of current to
the auxiliary battery using an optimized 6-stage charge algorithm.
Heavy-duty connectors can be used for connecting a variety of accessories from inverters (600W max)
A built-in 25A MPPT solar regulator circuit supports solar panels up to 42V and provides up to 25A (375W)
charge current to the battery.
ŸThe battery charge profile takes into account battery temperature with a sensor (located inside the
battery compartment) for safe charging under various conditions.
Max battery size :
Supported battery types (set to AGM by default) :
ŸLead-acid (Calcium, Flooded, AGM, Gel, VRLA)
ŸLithium-ion, LiFePO4
Temperature Compensation & battery protection :
Ÿ325mm x 180mm x 280mm (L x W x H)

Preparing for Installation
(Instructions on page 5)
The input cables must be terminated with a RED 50A coupler matching the one on the Power Pack DC25
marked "MAIN BATT".
If a solar panel input is used, it can be connected to the input marked "SOLAR PANEL".

Use 16mm cables for the input from the vehicle main battery and install the supplied 40A in-line fuse
close to the main battery on the positive cable (Fig 1).
Once the battery type is selected, a battery can be installed into the Power Pack DC25 and the RED
input cable connected (Fig 2).
Before installing a battery into the Power Pack DC25, select the correct battery type.
Make sure all connections are secure and terminated correctly with appropriate tools.
For applications where the Power Pack DC25 is installed in a vehicle, locate the Power Pack such that
the input cables are not restricted or under strain. The Power Pack should also be secured to prevent
movement.
Connect the supply from the main
battery (alternator) to the RED input
on the Power Pack DC25.
Install the fuse on the positive cable
close to the main battery.
Ensure terminals are crimped securely.

This is best done before the battery is installed into the Power Pack DC.
The battery type should be chosen before the auxiliary battery is installed.
For safety, the battery type cannot be changed if the auxiliary battery is already connected.
A power source connected to the MAIN BATT or SOLAR PANEL input is required to change the battery
type.

Remove screws from the left, right and under-side as
indicated.
The cover can now hinge open. The cover can now be opened fully to expose the
internal DC-DC system.
With the cover slightly open, unplug the remote
monitor cable.
Connect power to the MAIN BATT or SOLAR input.
The DC-DC system will now activate and show the
current battery selection.
Remove the cover of the internal DC-DC system by
loosening two screws on top.
Once the preferred battery type is selected, disconnect
the power source.
- Replace the cover of the DC-DC system.
- Re-connect the remote monitor plug and close the cover.
- Re-install the screws that were removed earlier.
- The auxiliary battery can now be installed.

The AGM battery type
is the default factory
setting.
To change this, press
the "Battery" button
until the desired type is
selected.

Installing Battery
Note : Select the battery type before installing the auxiliary battery. See page 5.
To hold a battery securely in the Power Pack, install the U-bolt and hold-down bracket.
It is best to lay the Power Pack on its side or end to do this.
Insert the U-bolt through the holes
drilled into the bottom of the
Power Pack.
Return the Power Pack to the
upright position.
Remove the Power Pack sliding lid
and insert the auxiliary battery into
the battery compartment.
Connect the positive (RED) and
negative (BLACK) cables to the
battery terminals.
Make sure the connections are
clean and tight
Take care not to over-tighten the
screws.
Attach the hold-down bracket,
washers and wing-nuts.

Connecting Solar Panels
Ignition over-ride (optional accessory)
CAUTION
The Power Pack supports the direct connection of
solar panels up to 42V through the heavy-duty connector
marked "SOLAR PANEL".
Note that if the solar panels have internal regulators,
connect them to one of the AUXILIARY IN/OUT
connectors instead.
This will bypass the Power Pack solar MPPT system.
Other charger brands can be connected to one of the
heavy-duty AUXILIARY IN/OUT connectors.
Charge currents exceeding 10A can be connected.
This port can support up to 10A charge current.
The Power Pack has a charge port specifically for use
with National Luna Intelligent Battery Chargers.
In order to connect other brands of chargers to this input,
a quick-connector cable is available separately.
Insert the charger quick-connector into the charge port
labeled "NL5 CHARGER" until it clicks securely.
Plug the larger end into a socket that provides a positive
voltage only when the ignition of the vehicle is ON.
This may be the case in some vehicles with "Smart
Alternators".
Plug the small end of the over-ride cable into the

In order to charge or supply power to accessories connected to any
of the plugs & sockets, the main switch on the Power Pack DC25
must be in the ON position.
If the Power Pack DC25 is not in use then it is best to turn the
switch OFF. This will completely isolate the auxiliary battery.

If the IGNITION SENSE input is used, the Power Pack DC25 will charge with input voltage above 12.0V
and stop when voltage drops below 11.5V.
The Power Pack DC25 will start to charge the auxiliary battery once voltage on the MAIN BATT input
exceeds 13.2V. It will stop charge once voltage drops below 12.6V after a short delay.
