GuaiGLong B0CCJ79XY4 12V 120AH LiFePO4 Battery User Manual

GuaiGLong B0CCJ79XY4 12V 120AH LiFePO4 Battery

Specifications:

• Model: GuaiGLong
• Voltage: 12V
• Capacity: 120AH
• Battery Type: LiFePO4

Interface Introduction

1. Waterproof plug (LD20, Output: 12V)
   This output port is for outputting 12V power supply. Maximum current: 20A. Used for low-power devices like sonar, speakers, LED lights, etc.

2. Anderson plug (50A)
   Maximum current: 50A. Used for devices with power less than 600W such as low- power electric motors, engines, etc.

3. Terminal (M8)
   Used for high-power devices (100A, MAX.1280W) like electric motors, engines, trolling motors, inverters, etc.

4. Charging Port GX20 (3-pin, 1 positive pole, 3 negative poles)
   Used to connect a charger for charging and discharging. Maximum current: 12A.

5. Display Screen 2 USB (5V, 3.1A)
   Displays percentage of remaining battery power and battery voltage. Note: The displayed electricity percentage may be inaccurate; estimate remaining electricity based on voltage.

Note:

The power of 12V LiFePO4 battery is concentrated between 12.2V-13.2V. BMS will cut off battery output when voltage is lower than 10.4V. During charging, the charger’s indicator changes from red to green when fully charged.

Product Usage Instructions

Using the Waterproof Plug (LD20):

Connect low-power devices like sonar, speakers, or LED lights to this port for a 12V power supply. Ensure the total current does not exceed 20A.

Using the Anderson Plug (50A):

This port is suitable for devices with power less than 600W such as low-power electric motors or engines. Do not exceed the maximum current of 50A.

Using the Terminal (M8):

Connect high-power devices like electric motors or inverters to this terminal. Ensure the power does not exceed 1280W and the current does not exceed 100A.

Charging and Discharging:

Utilize the GX20 Charging Port to connect a charger for charging the battery. The maximum charging current is 12A. Monitor the display screen to track remaining battery power and voltage.

FAQ

Q: How do I know if the battery is fully charged?

A: During charging, observe the charger’s indicator light; it will change from red to green when the battery is fully charged.

Q: What should I do if the displayed electricity percentage is inaccurate?

A: Estimate the remaining electricity based on the battery voltage range provided in the manual (12.2V-13.2V).

Interface Introduction

1. Waterproof plug (LD20,Output:12v)
   This output port is for outputting 12V power supply.
   This port has a maximum current of 20A and is used for low-power devices, such as sonar(fish detectors), speakers,LED lights,etc.

2. Anderson plug (50A)
   This port has a maximum current of 50A and is used for devices with a power of less than 600W, such as low-power electric motors, low-power engines, etc.

3. Terminal(M8)
   It is used to connect high-power devices (≤100A,MAX.1280W), such as electric motors, engines, trolling motors, inverters, and other high-power devices.

4. Charging Port
   GX20(3-pin, 1 positive pole,3 negative poles)
   It is used to connect a charger for charging and can also discharge,with a maximum current of 12A.

5. Display Screen
   2 USB(5V, 3.1A)
   It can display the percentage of remaining battery power and the voltage of the battery.

Please note:

• The percentage of electricity displayed on this display is inaccurate. When using it, you need to estimate the remaining electricity according to the voltage.
• The power of 12V LiFePO4 battery is concentrated between 12.2v-13.2v. When the voltage is lower than 10.4V, BMS will soon cut off the battery output.
• When charging,the indicator light of the charger changes from red to green to indicate full charge.
