22.5W Fast Charging Module TFT Color Screen 3.7V Ternary Lithium Battery Motherboard DIY Mobile Power Bank Module Supports PD/QC

Product features: 1. Multi protocol full compatibility: Supports mainstream protocols such as PD/QC/APPLE, and is compatible with fast charging of all devices 2. Four fold safety protection: overcharge/overdischarge/overvoltage/overheating intelligent protection to avoid safety hazards 3. TFT color screen display capability: real-time display of battery level/voltage/temperature, with clear status at a glance 4. Protection free board design: The motherboard integrates protection functions, and the battery can be directly soldered to save space and simplify assembly 5. Intelligent self-learning battery level: automatically calibrates the battery level display after the first use, accurately reflecting the remaining battery level

Product parameters: Product Name: 22.5W Fast Charging Module Input parameters: 5V3A/9V2A/12V1.5A Output parameters: 5V3A/9V2A/12V1.5A/10V2.25A Interface: Configure 1 Type-C fast charging port (rechargeable or output)+2 USB fast charging output ports Protocol: PD, QC, APPLE, FCP, SCP, VOOC Function: It has multiple protections such as overcharge/overdischarge/overvoltage/overheating, high conversion rate, and stable current and voltage Note: 22.5W is the super fast charging protocol, and bidirectional fast charging is the PD20W protocol. Multiple interfaces simultaneously output no fast charging Assembly instructions: 1. Due to the fragility of the motherboard screen, please power on and test the screen for normal operation before soldering it. If the screen cable is squeezed by external force, it may cause the screen to flower or explode. Please take care to protect the screen when using it. 2. In normal use, the battery wires are welded together, and methods such as wire twisting, alligator clips, and spring boxes can lead to insufficient power supply and affect charging and discharging. The positive and negative terminals of the battery need to be insulated and protected to avoid damage caused by contact with the motherboard during use. 3. Connect the B+position of the motherboard to the positive pole of the battery and the B - position to the negative pole of the battery. Do not connect them in reverse, as it will burn the motherboard and leave marks on the burned IC. This situation will only occur if they are connected in reverse or touched. 4. To connect the battery, a 3.7V ternary lithium battery should be used. Lithium iron phosphate batteries cannot be used. The batteries should be welded in parallel and cannot be connected in series. If the series voltage is too high, it will burn the motherboard. 5. The motherboard has a protection function, and welded batteries do not require a protection board. The battery protection board has a limit on the current, and if it exceeds the limit, the output will be disconnected. instructions: 1. Regarding the issue of activating mobile fast charging, there is a distinction between public and private protocols for mobile fast charging. This motherboard uses an intelligent fast charging chip that is compatible with mainstream public fast charging protocols in the market and can meet the fast charging needs of different s of phones. Before placing an order, please confirm whether your phone is compatible with public protocols to avoid triggering fast charging! Regarding the issue of motherboard heating during charging, when the power bank is in operation, the current passes through the motherboard and chip, causing energy conversion losses. This loss is dissipated in the form of heat. During fast charging, the power is higher and the heating is more pronounced, which is a normal physical phenomenon. 3. When the battery is just connected, the digital display of the power level may not be accurate. The power meter supports self-learning of battery capacity, and after a few cycles of charging and discharging, it will return to normal.
