Low Mode & Night Mode
Flickering LED is Low Mode @
Solid LED is Night Mode @
Both mode have only 10 Amp maximum output and the cooling fan does not rotate at all charging
stages so that the charger is virtually noiseless.
The Night Mode has an 8 hour timer and will automatically reset back to normal mode with
maximum 20 Amp charging current.
Low mode is more adaptive for battery with less than 70Ah and further extend the lower range of
battery capacity to 40Ah.
Both modes are ideal for use in caravan or campers where as the Night mode is good for situation
with high day time load and low load at silent night.
Equalization Mode (Recondition Mode)
This charging profile is only applicable to Lead Acid based battery especially wet type .It
reconditions the deeply discharged battery and reduces stratification ,counter sulfation found in
deeply discharged and infrequent used battery. It also gives battery cells a well balanced charge.
Once set, the charging algorithm is automatic. The charger will go through Soft Bulk (for deeply
discharged battery) -> Bulk -> Absorption -> Equalization -> Float charge stages.

Battery Charger installation and Connection
Observe the warnings & safety precautions before rushing to install and
operate the charger. Check battery condition, fill up cells for wet battery, clean
battery poles. Secure the battery charger in a well ventilated place, make sure
the mounting surface is flat and without soft covering material or loose paper
sheet. The air intake is at the bottom and air outlet at the Front Exhaust Hood.
It is recommended to install the charger in a vertical position for optimum
cooling and splash proof.
Before connecting or disconnecting the charging cable, unplug AC cord from
the mains.
First connect the Red cable to Positive + terminal of charger and the battery
Positive + Pole.
Then connect the Black cable to the Negative – terminal and the Negative –
Pole of the battery. Make sure all the connections are secured and well tighten
up, double check on the correct polarity.
After AC is on, check for the correct battery type, if not you can always change
to desire battery type by quick short presses without disconnection of the AC
mains or battery. P.5

The 6 Stage Charging Algorithms for Lead Acid Battery
There are two separate charging algorithms:
one for lead acid based and one for Lithium FePo4.
Lead acid based batteries ; wet , sealed , AGM
6 Stages: Soft Start--> Bulk --> Absorption ---> Float --> Standby --->
Refresh Cycle
This 6-Stage charger will give a fast and safe charging according to the state of
your battery, saves energy, and automatically refresh your battery.
Soft Start:
When battery voltage is less than 12V, charger will lower the initial charging
current to 10 Amp to avoid heating up and stress on the battery until battery
voltage rises to 12.4V then switches to normal Bulk Charge.
Bulk Charge:
This stage will give about 80% of the total charge to the battery. Charger is held
in giving out a constant charging current of 20Amp to the battery. Voltage
increases as the charging goes on bulk charge mode giving a steady 20Amp
current to the battery and the temperature of the battery increases as well.
Absorption Charge:
This will give the remaining 20% charge to the battery. When the battery
voltage rises to the voltage level of the selected battery type, the charging
switches to Constant voltage charging. The absorption time is adaptive to the
time spent on bulk charge and the battery type.
The absorption time is also is bounded by a set of upper and lower time limits.
Float Charge:
A low constant voltage charge to top up the battery for slight self discharge or
light occasional loading in order to keep the battery in a fully charged condition
all the time.
Standby Charge:
The charger will enter into an energy conversation (Standby) stage with lower
Float Voltage after long period of inactivity of 8 hours or more has been
detected. This Standby stage also helps to reduce grid corrosion. This will
decrease the gassing and corrosion to the positive terminal.
Refresh Charge
Charger will automatically give a refreshing cycle charge (fast bulk &
absorption, float) at 7 days interval of inactivity. This is to keep the electrolyte
and the cells of the lead acid battery in good working condition.
P.6

Equalization Charge:
It is only applicable to Lead Acid based battery especially wet type.
It reconditions the deeply discharged battery and reduces stratification, counter
sulfation found in deeply discharged and infrequent used battery. It also gives
battery cells a well balanced charge.
Once set, the charging algorithm is automatic. The charger will go through Soft
Bulk (for deeply discharged battery) -> Bulk -> Absorption -> Equalization ->
Float charge stages.
You can exit from Equalization charge to Float anytime by long press at the
SET button.
Sleep Mode & Half Power Mode
Both charge mode have only 10Amp maximum charging current in stead of
20Amp.
The cooling fan will be off all the time to ensure total silence of a quiet charging
operation.
Half Power mode is more suitable for batteries with less than 70Ah capacity.
The sleep Mode has an 8 hour timer, charger will go back to normal maximum
output of 20Amp
Battery with Loads connected such as in caravan, campers & etc.
The charger can be used as a stand alone automotive charger or connected to
battery all the time with and without load as long as the load is not more than
15Amp in normal mode or 7Amp in half power /sleep mode.
Lead Acid based batteries: LEAD / AGM
P.7

Charging Profile with Equalization charge set for Lead Acid based batteries.
LiFePO4 (LFP) battery
Caution: Never charge LFP battery when its temperature is below 0°C.
There is a special charge algorithm and treatment for Lithium FePO4 (LFP)
batteries to ensure safe and optimal charging adaptive to the special chemistry
of the battery which is quite different to Lead Acid battery. There are only two
active charging stages namely Bulk and Absorption, at the end of Absorption is
the inactive (no charging current) Standby Stage. There is no Float and no
automatic refreshing cycle charge and no Equalization Charge for LFP.
P.8

DC Source 13.5V
All 3 battery type LED are on at the same time in DC source mode.
Charger can be used as a constant 13.5V voltage DC source with start upload
limited to 2AMP and subsequent maximum continuous 13Amp load without the
battery.
Battery with load
A load can be connected to the battery during charging as long as the load is
not larger than the rated output of the charger. The maximum continuous load
should be less than 13Amp.
Supplied Accessories
Battery temperature sensor (only for lead acid based battery)
When connected to the battery temperature sensor, the charging voltages
changes inversely with the battery temperature such that charging voltage
decreases with rise of temperature and increases with drop of battery
temperature.
Optional Accessory
Remote control Module
It is an extension of the front panel of the charger with full sets of LED
indicators & the SET button. You can monitor the charging status and do all
sorts of setting on the charger without getting to the charger which is most
likely installed at hard to access spot. This optional Remote Control Module
comes with a 10 meter connection cable.

Protection
Over Temperature Protection of battery
When this sensor detects the temperature of battery over 60ºC, the charger will
decrease the charging current to 1Amp. When the battery temperature reduce
back to 60 ºC.
Over Temperature Protection of charger:
At high operating temperature charger will gradually decreases the output
power to protect the electronic components from further thermal stress and at
the same time keeps a safe and continuous charging. The charger will
decrease output current in 3 levels, while the charger temperature keeps on
increasing, it will decrease output current to 13Amp first, then 6Amp and finally
1Amp.
Short circuit protection by constant current method and auto reset when fault is
clear.
