Features: Comprehensive motherboard protection including overcharge/over-discharge/overvoltage/overheat safeguards. High conversion efficiency with stable current and voltage output.

Notes:
1. PD output: 100W; input: 65W
2. Screen illuminates for one minute upon motherboard startup during output/input, then automatically dims while maintaining operational status

Assembly Instructions:
1. Upon receiving the mainboard, first connect the charging cable for input testing. Observe the display status and confirm the screen illuminates before proceeding with soldering.
2. For normal operation, the battery wires must be soldered directly. Connections via wire twists, alligator clips, or spring clips may cause insufficient power supply, affecting charging/discharging. Ensure proper insulation protection for the 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 on the mainboard and the negative terminal to the B- pin. Do not reverse polarity, as this will burn the mainboard. Burn marks on the IC indicate reverse connection or accidental contact.
4. Use ternary lithium batteries only; lithium iron phosphate batteries are incompatible. 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 fast charging on phones: Phone fast charging protocols are categorized as public or proprietary. This motherboard employs an intelligent fast-charging chip compatible with mainstream public fast-charging protocols, supporting rapid charging for various phone brands. Verify your phone'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, causing energy conversion losses. These losses dissipate as heat. Higher power during fast charging results in more noticeable heat, which is a normal physical phenomenon.
3. The battery level display may be inaccurate immediately after connecting the battery. The battery meter supports self-learning of battery capacity and will function normally after several charge/discharge cycles.
