5. Battery Management System

The built-in lithium battery protection board can monitor the battery operation status in real time. It will cut off input and output for protection when over-charge, over-discharge, over-current, over-temperature occurs.

6. Transportation and Storage Precautions

For long-term storage, complete a charge-discharge cycle every 3 months. Do not drop during handling; stacking shall not exceed 4 layers; do not place upside down, keep front side upward.

7. Warnings and Notes

Please carefully read this specification and warning labels on the device before use. Improper operation may lead to overheating and damage of the unit. The company shall not be held responsible for any accidents resulting from non-compliant operations. Always follow the instructions for safe operation.

Warning

Keep the power supply away from heat sources and high-voltage places, avoid long-term direct sunlight exposure.
The product contains high-voltage components. Do not disassemble it privately to avoid safety accidents.
Do not put the power supply into water or fire.
Do not reverse the positive and negative poles of the power supply. Do not short-circuit the positive and negative poles with metal objects.
Avoid severe physical vibration and impact; do not hit, drop or step on the power supply.
Disassembly or assembly without manufacturer permission and guidance is strictly prohibited.
Do not use power supplies of different manufacturers, types and models in combination.

Note

The load equipment must meet two conditions for use: ① Input power < rated power of power supply; ② Starting power at boot < peak power of power supply.
The power supply will automatically activate protection and turn off output when low battery, excessive load power or over ambient temperature.
Please charge the power supply within 15 days after being exhausted.

Use matched or recommended professional lithium battery charger only.

Stop using immediately if abnormal conditions such as peculiar smell, discoloration, abnormal noise, liquid leakage or severe deformation occur.
If electrolyte leaks and splashes on skin or eyes, rinse with clean water immediately and seek medical treatment.
Place the power supply out of reach of pets and children; keep children away from the product.
It is forbidden to use multiple units in series or parallel connection. Please contact the manufacturer for consultation if series/parallel application is required.
