Solder the main board's positive red wire to the protection board's B+ position and the negative black wire to the protection board's P- position.

After installing the mainboard and battery, secure the battery with adhesive tape. For certain battery models with thickness discrepancies relative to the casing, assess whether spacers are needed to prevent a sagging sensation when pressing the casing after assembly. Issues like battery rattling or casing deformation due to failure to check thickness differences or secure the battery with tape during assembly constitute improper installation. We assume no responsibility for casing damage or battery failure resulting from disassembly.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e5. The snap-fit casing is not designed for repeated disassembly. Always test all functions—motherboard output\/input, fast charging, buttons, display, etc.—before closing the casing. Ideally, perform several charge\/discharge cycles to confirm functionality before sealing. Issues arising from assembling and closing the casing without prior testing constitute improper assembly. We assume no responsibility for casing damage or battery failure resulting from disassembly required due to such issues.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e\u003cbr\u003eInstructions:\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e1. Regarding activating fast charging for your phone: Fast charging protocols are categorized as public or proprietary. This motherboard incorporates an intelligent fast-charging chip compatible with mainstream public fast-charging protocols, supporting rapid charging for various smartphone brands. Before ordering, please verify your phone's compatibility with public protocols to ensure fast charging functionality.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e2. Regarding heat generation during charging: When the power bank is in operation, current flows through the motherboard and chips. Energy conversion inevitably involves losses, which dissipate as heat. During fast charging, higher power consumption results in more noticeable heat—this is a normal physical phenomenon.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;font-family:arial, helvetica, sans-serif\"\u003e3.
