HOW IT WORKS

HOW IT WORKS:

When the charger is connected to AC voltage and the output cable is not connected to anything, the LED Power Indicator on the panel will be solid on, and bank panel will display one of the battery types selected last time. Select the battery type to be charged by pressing the mode button. The charger will remember the selection each time and automatically determine the battery type selected last time after the next input connection.
Charging 12-Volt Batteries:
Charging 12V LiFePO4 Lithium Batteries: After the 12V LiFePO4 Lithium battery is correctly connected to the output cable of the charger, the charger enters 10A normal rated current charging mode. During the charging process, the LED Power Indicator is solid Red. As the battery voltage rises, the charging current gradually reduces. When the charging current drops to 0.8A±0.3A automatically, the 100% LED indicator light will be solid green which indicates that the lithium battery has reached a full charge. Our charger will shut off automatically, and will not trickle charge. The green LED indicator light will keep solid during this process. After fully charged for 24 hours, Our charger will use 2.0A±1A charging current to charge the battery again. After disconnecting the battery, the charger will return to standby state. All four Charging Status LED Indicators are off, LED Power Indicator and Battery Type
LED Indicator will be on.
Charging 12V Lead Acid & AGM Batteries: After the 12V Lead Acid /AGM battery is correctly connected to the output cable of the charger, the charger enters 10A normal rated current charging mode. During the charging process, the LED Power Indicator is solid Red. As the battery voltage rises, the charging current gradually reduces. When the charging current reaches 0.8A±0.3A automatically, the 100% LED indicator light will be solid green. After a full charge, if the battery voltage drops to 12.9V±0.2V, then the 2.0A±1A current is used to trickle charge the battery. When the charging current drops to 0.8A±0.3A, the battery will stop charging. During this process, the 100%LED indicator light will be solid green. After disconnecting the battery, the charger will return to standby state. All four Charging Status LED Indicators are off, LED Power Indicator and Battery Type LED Indicator will be on.

PROTECTION FUNCTION

a. Short-circuited or Reverse Connection Protection: There is no DC output for the charger and the LED Power Indicator flashes quickly when the output terminals are short-circuited or reverse connected to the battery.

b. No-load Protection: There is no DC output when the batteries are not connected.

c. Over temperature Protection Function: When the temperature of the radiator inside of the charger reaches 176 °F, the charger will automatically reduce the output current for over temperature protection. . When the internal temperature of the charger cools down, the charging current will gradually adjust efficiency and charge normally again at 10 Amps. A waterproof cooling fan is installed outside the charger. When the bottom aluminum stretched plate’s temperature is higher than or equal to 122°F the fan will work. When the bottom aluminum stretched plate’s temperature is lower than or equal to 104°F, the fan will stop working.

d. Automatic Shutdown after Full Charge: The charger will automatically turn off after the battery is fully charged according to the charger’s programing. Only when AC power is disconnected or the battery is recommended, the charger will recharge.
Protection Function

OPERATION METHOD

MATCHING THE CHARGER WITH “AC POWER GRID” AND THE “BATTERY PACK”.
Match for chargers and AC power grid: Before using the charger, please make sure the AC power grid voltage and its frequency are in the range specified in the “Basic Parameters” label. If the voltage is below the nominal input voltage, the charger will shut down for protection (AC voltage is less than 105V), and it will affect battery charging performance.
Match for the charger and battery pack: There is applied battery specification in the “Basic Parameters” label on the charger side. Please confirm whether battery type (12V LiFePO4 / Lead Acid / AGM OR 24V Lithium (LiFePO4) OR 36V Lithium (LiFePO4) Batteries), and battery pack rated voltage (V)match those on the “Basic Parameters” label. If they do not match, it is likely to cause less charge or overcharge and even cause permanent damage to the battery pack, bringing serious economic losses.
AC POWER WIRE, DC CHARGING CABLE POLARITY, AND PRECAUTIONS
AC input wire is at the side of the charger: I, N, and Ground are, marked on the input cable plug. Please distinguish correctly. I, N, earth on AC plug should correspond with those of socket outlet. The charging output cable is at the side of the charger: You can distinguish the positive and negative of the output cable by colors. Red cable is to connect battery “+” and Black cable is to connect battery “-“. Using their M8 ring terminals on the charging output cable to connect with the correspond battery terminals. The polarity of the charging socket should be consistent with the polarity of the charging plug polarity, otherwise, it cannot charge. Please check before using.

USAGE INSTRUCTIONS

First, firmly connect the charger output plug with the correct battery type, and then firmly connect the AC plug with the AC outlet.
After the correct connection and battery type selection, the current will be output from the charger, at the same time the Charging Status LED Indicators will show the Battery Charging Percentage.
After fully charged, please disconnect the plug between the charger and the alternating current.

ASSEMBLY AND DIMENSION

When a fixed position is needed, it is recommended to fix the charger in a safe position.
The safe space around the charger should be more than 30mm.
The diameter of the fixed hole is 6.5mm, and it is recommended to fix it with M6 screws.

WARNING

The appliance is not for the usage of any person or children with retarded physical, sensory or mental abilities or lack of understanding and knowledge.
Children must not clean and do any other maintenance of it without any supervision.
Use this charger for charging 12V LiFePO4 / Lead Acid / AGM OR 24V Lithium (LiFePO4) OR 36V
Lithium (LiFePO4) Batteries only based on different models.
Do not use this charger to supply power to an extra-low-voltage electrical system or charge dry-cell batteries because charging dry-cell batteries may cause burst.
If it is necessary to remove the battery from the vehicle/boat to charge it, always remove the grounded terminal from the battery first.
Do not use the battery charger unless the battery voltage matches the output voltage rating of the charger.
Always shield eyes when working near batteries. Do not put wrenches or other metal objects across the battery terminal or battery top. Arching or explosion of the battery can result.

CAUTION

To reduce the risk of injury, the charger only charges 12V LiFePO4 / Lead Acid / AGM OR 24V Lithium (LiFePO4) OR 36V Lithium (LiFePO4) Batteries only based on different models. Other types of batteries may burst to cause personal injury and damage. Do not attempt to recharge any non-rechargeable batteries.
