CHARGING 12V LIFEPO4 BATTERY:
1. Once the 12V LiFePO4 battery is correctly connected to the charger’s output cable, the
charger will enter a 20A normal rated current charging mode.
2. Throughout the charging process, the LED Power Indicator will remain solidly lit. As the
battery voltage increases, the charging current gradually decreases.
3. When the charging current automatically drops to 1.5A±0.5A, the 100% LED indicator will
illuminate solid green, indicating a fully charged battery.
4. After the LiFePO4 battery reaches full charge, it will no longer have trickle charging
current, and the green LED indicator will remain solid during this phase.
5. Following a full charge for 24 hours, the charger will apply a 1.5A±0.5A charging current to
maintain the battery.
6. Once disconnected from the battery, the charger will return to a standby state, with all
four Charging Status LED Indicators turned off. The LED Power Indicator and Battery Type
LED Indicator will remain illuminated.
CHARGING 12V LEAD ACID / AGM BATTERY:
1. Once the 12V Lead Acid / AGM battery is correctly connected to the charger’s output
cable, the charger will enter a 20A normal rated current charging mode;
2. Throughout the charging process, the LED Power Indicator remains solidly on. As the
battery voltage increases, the charging current gradually decreases;
3. When the charging current automatically drops to 1.5A±0.5A, the 100% LED indicator light
will turn solid green, indicating a fully charged battery;
4. When the charging current drops to 0.8A±0.3A, the battery will stop charging. During this
phase, the 100% LED indicator light remains solid green;
5. After reaching a full charge, if the battery voltage drops to 12.9V±0.2V, a 1.5A±0.5A current
is used for trickle charging;
6. After disconnecting from the battery, the charger will return to standby mode with all four
Charging Status LED Indicators turned off. The LED Power Indicator and Battery Type LED
Indicator will remain illuminated.
When the charger is connected to AC voltage and the output cable is unconnected, the LED
Power Indicator on the panel remains solid, and the bank panel displays the last-selected battery
type. To choose the battery type for charging, simply press the mode button. The charger will
retain your selection, automatically recognizing it each time you connect the input in the future.

LED INDICATORS EXPLANATION
25% Red LED The 25% Charge LED will light up when the battery voltage is
lower than 12.5V.
50% Red LED The 50% Charge LED will light up when the battery voltage is
higher than 12.5V but lower than 13.7V.
75% Red LED The 75% Charge LED will light up when the battery voltage is
higher than 13.7V.
100% Red LED
All the Charge LEDs will light up when fully charged.
“ACTIVATE” MODE BUTTON:
Inside the LiFePO4 battery, there’s a low voltage protection PCBA. When the low-voltage
protection activates, the battery won’t provide voltage output at its terminals, and the charger
can’t charge it. To initiate “ACTIVATE” charging:
1. Connect the AC cord to an electrical outlet;
2. Press the MODE button to select the LiFePO4 battery charging mode;
3. Continuously press the MODE button on the bank panel for 3-5 seconds. The LiFePO4
Battery Type LED Indicator will ash slowly;
4. Attach the ring terminals on the output cables to the battery terminals correctly;
5. Once connected, the 12V LiFePO4 battery bank charger will deliver a pulse output of
1.5A±0.5A to charge the 12V LiFePO4 battery until it exits low-voltage protection. The
charger will enter normal charging mode;
6. During the pulse charging state, if you continuously press and hold the button on the panel
for 3-5 seconds, it will exit the “ACTIVATE” charging function, and the charger will return
to standby mode, with only the LED Power Indicator illuminated.

1. MATCHING THE CHARGER WITH THE AC POWER GRID AND BATTERY PACK:
Before using the charger, ensure that the AC power grid voltage and frequency fall within
the specied range indicated on the “Basic Parameters” label. If the voltage is lower than the
nominal input voltage (less than 220V), the charger will automatically shut down for protection
and affecting battery charging performance.
Additionally, for compatibility between the charger and the battery pack, refer to the battery
specications provided on the “Basic Parameters” label on the charger. Conrm that the
battery type (12V LiFePO4 / Lead Acid / AGM Batteries) and the battery pack’s rated voltage
(V) match the information on the label. Mismatched settings can result in undercharging,
overcharging, or even permanent damage to the battery pack or charger.
2. AC POWER WIRE, DC CHARGING CABLE POLARITY, AND PRECAUTIONS:
AC input wire: On the side of the charger, you will nd markings for I, N, and Earth on the
input cable plug. Please ensure correct identication. The I, N, and Earth markings on the AC
plug must correspond with those of the socket outlet.
Charging output cable: The charger’s output cable is equipped with distinctive colors. The red
cable connects to the battery’s “+” (positive), while the black cable connects to the battery’s
“-” (negative). Use the M8 ring terminals on the charging output cable to connect them to the
corresponding battery terminals. It is crucial that the polarity of the charging socket matches
the polarity of the charging plug; otherwise, charging will not be possible. Always verify this
before using the charger.
Following these guidelines will help ensure safe and efcient charging of your batteries.

SHORT-CIRCUIT OR REVERSE CONNECTION PROTECTION:
When the output terminals are short-circuited or reverse-connected to the battery, the
charger will not provide any DC output. In this case, the LED Power Indicator will ash rapidly.
NO-LOAD PROTECTION:
If the batteries are not connected, the charger will not output any DC current.
OVERTEMPERATURE PROTECTION FUNCTION:
When the temperature inside the charger’s radiator reaches or exceeds 80°C±5°C, the
charger will automatically reduce the output current as a safety measure against overheating.
As the internal temperature decreases, the charging current will gradually increase, eventually
returning to the maximum of 20A. The charger includes a waterproof cooling fan mounted
externally. This fan operates when the temperature of the bottom aluminum stretched plate
reaches or exceeds 50°C±5°C and stops when it falls below 40°C±5°C.
AUTOMATIC SHUTDOWN AFTER FULL CHARGING:
The charger features an automatic shutdown function once the battery reaches a full charge,
following the charger’s pre-programmed parameters. The charger will only initiate a new
charging cycle when AC power is disconnected or when the battery requires further charging,
ensuring optimal battery health and safety.
PROTECTION
FUNCTION
ASSEMBLY AND DIMENSION
ࠠFor secure installation, it is advisable to afx the charger in a stable position.
ࠠEnsure there is a clearance of at least 30mm around the charger for safety.
ࠠTo secure the charger, use M6 screws with a recommended hole diameter of 6.5mm in the
bottom aluminum stretched plate.
ࠠAvoid placing the charger directly above or below the battery being charged, as gases or
uids from the battery can corrode and damage the charger.
ࠠNever operate the charger in an enclosed space or obstruct ventilation in any way. When
charging, ensure the battery is located in a well-ventilated area.
ࠠFamiliarize yourself with all specic precautions provided by battery manufacturers,
including whether to remove or keep cell caps on during charging and recommended
charging rates.
