2. Motherboard display illuminates for one minute upon output/input activation, then automatically dims while maintaining operational status

Assembly Instructions:

1. Upon receiving the mainboard, first connect the charging cable for input testing. Verify the display functions correctly before proceeding with soldering.

2. For normal operation, battery leads must be soldered directly. Connections via twisted wires, crocodile clips, or spring terminals may cause insufficient power supply, affecting charging/discharging. Ensure proper insulation of battery terminals to prevent accidental contact with the mainboard during use, which could cause damage.

3. Connect the battery positive terminal to the B+ pin and the negative terminal to the B- pin on the mainboard. Reverse polarity will burn the mainboard; burnt ICs will show traces, occurring only with reverse connection or accidental contact.

4. Use ternary lithium batteries only; lithium iron phosphate batteries are unsuitable. Solder the battery in a 4-series configuration to the protection board before connecting to the mainboard. Refer to the detailed diagram for specific soldering methods.

Usage Instructions:

1. Regarding activating mobile phone fast charging: Mobile fast charging distinguishes between public and proprietary protocols. This motherboard employs an intelligent fast-charging chip compatible with mainstream public fast-charging protocols, supporting rapid charging for various smartphone brands. Verify your device's compatibility with public protocols to ensure fast charging functionality.

2. Regarding heat generation during charging: When the power bank operates, current flows through the mainboard and chip, resulting in energy conversion losses. These losses dissipate as heat. During fast charging, higher power consumption causes more noticeable heating, which is a normal physical phenomenon.

3. Initial battery level display may be inaccurate upon connection. The battery meter features self-learning capacity calibration; it will normalise after several charge-discharge cycles.
