Product Specifications:

Charge/Discharge Parameters: 18W@5V 3A/9V 2A/12V 1.5A

Supported Lithium Battery Voltages: 3.7/4.2V (default), 3.85V/4.35V (reserved via jumper pads)

PCB Dimensions: 28*18*5mm

Pre-drilled mounting holes, compatible with M2 screws

Important Notes:

1. Ensure correct battery polarity (positive/negative). Reverse connection will cause burnout!

2. Upon receipt, connect only the charger without attaching the battery. A steady LED indicates module functionality. After verification, solder the battery. Post-soldering, reconnect the charger to activate the module before external output.

3. Charging current depends on battery capacity, discharge rate, current battery voltage, cable length/gauge, ambient temperature, etc.

4. High-power fast-charging module; recommend using batteries >10000mAh.

5. Maximum battery-side current may reach 5A; use silicone cables <20AWG with lengths <7.5cm.

6. Older batteries with higher internal resistance may cause inaccurate charge measurement due to voltage drop across the module's high current. Use low-resistance, high-rate batteries.

7. Compact design prioritizes portability over extensive heat dissipation. Avoid touching the chip's rear heat dissipation area during charging. Noticeable heat generation occurs during fast charging. The chip includes built-in overheat protection; reduced current during prolonged charge/discharge cycles is normal. For sustained full-power operation, add external heat sinks to the rear.

8. The module supports most 18W fast charging protocols.

9. The module will not output power when a device without CC protocol is inserted into the Type-C port.

10. Using this module requires some theoretical knowledge and hands-on skills. Please consider these factors before purchasing.
