Features 1. Robust 20V/5A output capability meets high-speed charging and discharging demands, enhancing operational efficiency 2. Built-in intelligent buck-boost circuitry supports diverse voltage input/output scenarios, compatible with multiple devices 3. Bidirectional lithium battery charging/discharging suitable for power banks, energy storage systems, and similar applications 4. Intelligently identifies device requirements for safe and efficient current/voltage matching 5. Precisely matches battery operating voltage range to ensure charging/discharging safety and battery longevity Parameter Type-C Port: PD100W 20V5A USB Ports: SCP22.5W 4.5V5A, 18W/20W 9V2A Battery Percentage Display Current/Voltage Display Precautions: 1. Never solder while energized. When soldering the main board's + and - wires, ensure they are de-energized to prevent 99.99% of accidents. 2. The main board only has + and -. Soldering while energized risks burns from hand tremors. Always disconnect power before soldering, connecting the main board's + and - first. The battery pack's negative terminal must be soldered last! The motherboard's two wires cannot balance the battery; the balancing protection function resides on the lithium battery protection board. 3. The first power-on may not display the battery level accurately; it will recover after a few cycles. 4. The default capacity is 500mAh per cell. Significant variations may cause inaccurate battery level display, but this does not affect other functions. There is no need to worry about overcharging or over-discharging.
