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 (120A)
This port has a maximum current of 80A and is used for devices with a power of less than 1800W, such as low-power electric motors, low-power engines, etc.

3.Terminal(M10)
It is used to connect high-power devices (≤200A,MAX.2560W), 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 20A.

5.Car cigarette lighter socket(Max.20A)
This socket can provide power to car electronic products such as car refrigerators and air pumps.

6.USB&PD
5V USB qc3.0 Fast charging
PD Fast charging

7.Display Screen
USB & PD
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.

Built-in BMS(optional Bluetooth)
12V 300AH:≤200A (with 200A BMS)
12V 300AH-bluetooth: ≤200A (with 300A Bluetooth BMS)
Built-in BMS(optional Bluetooth function) battery management system,functions:
1. over charge protection.
2. over current protection.
3. over voltage protection.
4. discharge protection.
5. short circuit protection.
6. over power protection.
7. temperature protection.

NOTE
The red indicator light indicates that the charging is in progress, and the green indicator light indicates that the charging is completed.
