Usage Instructions:

1. Connect the Batteries: Use 2S–5S lithium battery packs with a proper BMS protection board. Ensure polarity and wiring sequence are correct.

2. Wiring: Use thick wires (16AWG or higher) for main power connections to handle up to 10A safely.

3. Avoid Test Clips: Do not use alligator clips for testing; use properly soldered or crimped connections.

4. Power Display: The LED screen automatically shows charging voltage and current during use.

5. Fast-Charging Detection: The module automatically identifies connected devices and adjusts output according to supported protocol (QC, PD, etc.).

6. Cooling: Ensure good ventilation or a small heatsink for continuous high-power operation (especially above 60W).

7. Compatibility Check: Verify your devices support PD3.0 or QC3.0 before connecting. Incompatible devices may charge slowly or not at all.

8. Battery Precaution: Do not use nickel-metal hydride, dry cell, or lead-acid batteries. Only lithium-based cells are supported.

9. Preset Capacity: Set your battery capacity in the display if supported by your module version for accurate readings.
