Important Safety Instructions
WARNING
This battery charger is not intended for use by children or infirm persons
without supervision.
- During the charging process, do not use a naked flame near a battery. Batteries generate explosive gasses during the charging process that may explode.
- Never smoke or light cigarettes near a battery.
- Do not place tools on top of a battery or allow tools to fall on the battery to prevent the chance of a short circuit and sparks.
- Always wear eye protection when charging a battery.
- Ensure charging and testing is conducted in a well-ventilated area.
- Inadequate ventilation may over-heat the charger and cause in-efficient operation.
- This battery charger is not intended for outdoor operation. Do not expose it to moisture or extreme weather conditions.
- The ACID/FLUID within a battery is highly corrosive and poisonous. It can produce flammable and toxic gases when recharged and will explode if ignited. When working with batteries, always wear eye protection, remove jeweler and ensure the area is well ventilated. If spilt – it will cause severe burning to eyes, skin, clothing, damage paintwork and corrode many metals. Ensure that power is disconnected from any appliance in the vicinity of the spill and immediately wash any area that has been affected with water.
The warnings, cautions and instructions detailed in this instruction manual cannot cover all possible conditions and situations that may occur. Common sense and caution are factors which cannot be built into this product and must be supplied by the operator.

- Press “Battery Type Selector” to select the corresponding battery type, and batteries can be re-selected during charging by long pressing the button
- Installation Options I Instructions
INSTALLING THE CHARGER
Installation of this unit will require twin core wiring – and suitable cable
connectors (not included). Suggest ground circuits can be connected to chassis
to shorten cable length.
See specifications page for details.
Any existing cables used in conjunction with this charger are required to be
checked to ensure they are a suitable gauge.
If the gauge does not meet the minimum required specification in table on page
6, please replace them.
- Locate where you are going to install the DC-DC charger. Ensure the charger is located in a suitable dry area in the vehicle or caravan.
- Ensure the charger is securely mounted. Charger can be mounted overhead, vertically or horizontally.
- Next, measure required cable length from the main vehicle battery through to the location of the DC-DC charger.
- Ensure ALL cabling meets specification and will not be exposed to excessive heat/moving parts or abrasion.
- You can connect the optional ACC wire to the ignition of your vehicle.
- If the charger is located in a camper/caravan we recommend the use of an Anderson style plug between the tow vehicle and the camper/caravan as shown below.
- Fit Anderson style plug connectors on either end of the twin core cables.
- Connect the main battery to the charger – make sure polarity(+ & -) are correct.
- Connect the solar panels to the charger – make sure polarity(+ & -) are correct.
- Connect the auxiliary battery to the charger – make sure polarity(+ & -) are correct.
- Ensure unused cables (e.g. ACC wire) are insulated and secured against movement.
- Check all connections are tight.
Suggested installation to vehicle only
Main Vehicle Battery
Charger
Suggested installation to vehicle with caravan.
It is recommended to install 60A fuses or circuit breakers between the charger
and each battery on the wires, located close to the batteries.
Operating The Charger
CHARGER DISPLAY
DC BATTERY
Once correctly installed, charger will apply DC charge in priority automatically.
- Start the vehicle and let it idle.
- The charger will now recognize that there is charge being applied to the main starting battery.
- Once the main starting battery has reached 13.0V the charger will begin to charge the auxiliary battery.
- The initial default setting is for Lead Acid/Gel batteries (Select battery type before connecting to auxiliary battery).
- If you are charging a battery with a different chemistry simply change the battery type by pressing the battery type selector button on the front panel of the charger. (Select battery type before connect to auxiliary battery. Change battery type by a long button press if connected to auxiliary battery already)
- Once selected, the charger will remain on this battery type until it is changed.
- The charger will continue to operate even after the vehicle has been switched off, however once the main starting battery falls below 12.SV the charger will automatically shut off.
- SOLAR INPUT (WORKS ONLY WHEN DC BATTERY INPUT IS NOT AVAILABLE)
- Once the input plug is connected with the solar panel, the charger will transfer to solar charge mode.
- Solar charging requires an input of 16V – 25V from solar panels. When available solar panel voltage falls below 16V no charge will be delivered to auxiliary battery.
Specifications
LifeP04 has
5 charge stages.
WARNING
Failure to use recommended wiring will severely impacts on performance of
DC charge.
Charging Stage
Qualification
The charger will test the battery for faults. If the battery voltage lower
than 2V, it cannot be charged. Where the voltage is higher than 2V, move to
step 2.
If battery voltage between 2V and 12V but fully charged in 5 minutes, charger
will identify this is faulty battery and be beeping and POWER ON light
flashing.
Recondition
After the charger identifies the battery voltage, it will start to charge the
battery with a small current to activate the battery and improve battery
charging efficiency.
Bulk Charge (Constant Current Stage)
Maximum charge current is delivered to the battery, minimizing charge time.
Absorption (Constant Voltage)
With the increase of battery voltage, the charging current to the battery will
then reduce in order to avoid battery overcharge.
Full and Analysis
When the battery voltage level reaches a fully charged state, the charging
current will drop to 0. The charger will then shut off all output and measure
the voltage drop over 1 minute, before entering the next charging stage.
Maintenance
The charger will continue sending small pulse current charge to the battery,
keeping voltage on about 13.5V. If voltage drops 13V, stages 1-5 will repeat.
Note: The battery charger will analyze the condition of the battery in stage 5
and may not perform this function.
Charging algorithm will change according to battery type.
CHARGING VOLTAGES

NOTE Battery manufacturers sometimes specify charging voltages. Not observing their charging instructions may void your battery’s warranty.
Trouble Shooting
- Charger won’t indicate charging.
- Battery won’t charge.
- Battery won’t fully charge or hold charge.
- Lithium-Ion Batteries in Sleep Mode
Beeping
- Charger not connected to battery.
- Check terminal connection.
- Battery is not 12V.
- Verify that all wiring meets specifications.
- Check condition of batteries.
- Check performance of alternator.
Batteries that are over 3 years old; severely
- This DC-DC charger cannot charge a lithium-ion (LiFePo4) battery in sleep mode. To charge the lithium-ion (LiFePo4) battery, first make sure the DC- DC charger is correctly connected to the battery. Then select the “LiFePo4” mode, and long press
- “POWER” for Ss. The “charging” (red) indicator will flash for 10s. Once the battery is out of sleep mode, the “charging” (red) indicator will be constantly on and the DC-DC charger begins to charge the battery. Otherwise, the DC-DC charger will enter the standby state and the “Power On” indicator will be on. When the charger and battery are reverse connected, the charger has no output (reverse polarity protection).
