Ⅱ、Operating Instructions

2.1 Battery Discharge Instructions

Before connecting the battery, please use the matching cable provided by our company to connect the product. Prior to powering on, carefully verify that the battery meets the product specifications.
Set the power switch to the ON position. The product operation indicator will illuminate green, indicating normal output. The device may then be connected and used. Set the switch to the OFF position to power off the product.
If the device will not be used for an extended period, please disconnect the input cable to better preserve and prolong battery life.

2.2 Current Charging Instructions

1. When the battery charge is insufficient, an adapter or solar panel may be used to charge the battery. The supply voltage of the adapter or solar panel should be selected within the range of 5 to 25 VDC.

2. The charging port input uses a DC5525 connector with center positive and outer negative polarity. Please verify the voltage and polarity before connecting, and ensure the power switch is set to the ON position.

3. After being fully charged, the device will automatically stop charging. At this time, please unplug the charger or the input cable of the solar panel.

5. Hazard Warnings

1. Do Not Disassemble Internal Components of the Product

The product includes protective mechanisms and circuits to prevent hazards. Improper disassembly may compromise protective functions, potentially causing the product to overheat, emit smoke, or ignite.

2.Do Not Reverse Battery Polarity

Do not reverse the battery’s positive and negative terminals; doing so will cause excessive current flow and damage the fuse.

3. Avoid using the device near heat sources.

Do not operate near open flames, ovens, or in environments exceeding 80℃; overheating may cause internal short circuits, leading to heating, smoke emission, deformation, or fire.

4. Do not immerse the product to prevent moisture ingress into the internal circuitry.

Do not use the device in humid environments, as this may cause overheating, smoke, or fire.

5. Do not disassemble the device while it is powered.

When the product is in operation, as it is connected to an independent battery, always power off and disconnect the power cord before disassembly to ensure all output terminals are de-energized.
