PD output 100W, input 65W2. When the motherboard starts the output/input, the screen will light up for one minute and then automatically turn off to maintain the working stateAssembly instructions:1. The motherboard has been received. First, connect the charging wire for input testing, check the status of the display screen, confirm that the display screen can light up, and then proceed with soldering.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 can only occur if they are connected in reverse or touched4. To connect the battery, a ternary lithium battery should be used, and a lithium iron phosphate battery cannot be used. The battery should be welded in series to the protective board before connecting to the main board. The specific welding method can be seen in the detailed diagram.Instructions for Use:1. Regarding the issue of activating mobile fast charging, there is a distinction between public and private protocols for mobile fast charging. The 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 brands of phones. 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, resulting in energy conversion loss. This loss is dissipated in the form of heat, and during fast charging, the power is higher and the heating is more pronounced. This 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 battery capacity self-learning function and will function normally after a few cycles of charging and discharging.Shipping List:Module x2
