Features
1. Dual battery options: Lithium Iron Phosphate (3.65V) and Ternary Lithium (4.2V); customers can choose freely
2. Multiple ports support charging of various devices; when multiple ports are used simultaneously, only 5V/4.2A is supported
3. Integrated flashlight function and a low-current mode optimized for low-power devices, expanding practical application scenarios
4. Comprehensive support for open protocols including QC, PD, FCP, SCP, and VOOC, ensuring excellent fast-charging compatibility
5. Large-area mainboard with optimized heat dissipation structure; optional high-temperature startup fan (active cooling) or aluminum heat sink (passive cooling)
6. Built-in battery temperature monitoring mechanism tracks temperature rise in real time, effectively extending cell cycle life
7. Equipped with a color display that intuitively shows parameters such as voltage, current, power, and capacity, providing a clear and comprehensive overview

Important Notes
1. The wires connecting the external battery to the mainboard must be capable of handling 10A current. Use copper wire with a cross-sectional area of at least 1 mm²; for standard wire, use 1.5 mm². There is no need for excessively thick wire, but it must not be too thin either, as the current at the battery terminals is very high, and using too thin a wire poses a safety hazard.
2. The mainboard comes with a built-in protection chip; do not add an additional protection board to the battery. If one is present, remove it and connect the battery cells directly to the mainboard.
3. When testing the mainboard using alligator clips, do not charge a smartphone. If you need to charge a smartphone, you must solder the connections; alligator clips provide unstable contact, which can easily prevent fast charging, cause power interruptions and reboots, or even damage the mainboard.
4. You may use 3.2V/3.65V lithium iron phosphate (LFP) batteries. Depending on the selected options, you may also use 3.7V/4.2V 18650, polymer, or ternary lithium batteries; high-capacity cells are also acceptable. Multiple cells must be connected in parallel only; do not connect them in series. Do not use disposable alkaline batteries, NiMH, lead-acid, or NiCd batteries. If the battery level display is inaccurate upon first power-up, simply discharge the battery completely and then recharge it fully.
5. The mainboard must be preset with the battery capacity. The default preset is 10,000mAh; you can replace the resistor yourself later.
