22.5W Bidirectional Fast Charging DIY Motherboard Kit Mini 5A Version Mobile Power Module Circuit Board Electronic Modules Kits

Description

Product selling points: 1. Use high-quality materials to ensure product quality 2. Small size, high power, high efficiency, complete protocols, and mainstream open protocols are basically supported 3. The module is suitable for 3.7V lithium batteries, including polymer, 18650, 21700 and other lithium batteries; Ensure that the battery is not aging, the battery can be connected in parallel but not in series 4. The module has a relatively small volume and limited heat dissipation area, and high-power output heating is a normal phenomenon 5. The product has a wide range of applications and is suitable for various industrial DIY occasions Parameters: Full protocol, mainstream open protocols basically support charging current up to 5A, efficiency up to 96%, output power up to 22.5W, efficiency up to 95% Automatic load detection/light load detection High current USB output interface Support low current mode Support digital tube display and LED light power indicator Output overcurrent/short circuit protection Charging timeout/overvoltage protection Support PPS/PD3.0/PD2.0 Support QC4+/QC4/QC3.0/QC2.0 Supports FCP and SCP (5V4.5A or 4.5V/5A) Support FCP, SCP, HSCP Support SFCP Charging the battery supports PD3.0/PD2.0 AFCFCP,SCP ,PE1.1 Precautions for use: 1. The battery and motherboard cables should not be too thin, try to be thicker. Fast charging boards are required to be able to carry 10A current, and non fast charging boards must also be able to carry 7A current. It can’t be too long either, the interface needs to be soldered. 2. Batteries can only be connected in parallel (the number of parallel connections is not limited), and cannot be connected in series. Connecting in series will burn the motherboard. 3. For normal use, the battery must be welded (twisting the wires will result in insufficient power supply), and if the battery is reversed, the motherboard will burn out. Be careful. Try to make the line as thick and short as possible. 4. When connecting the battery, make sure to connect a 3.7V battery and not other batteries. Ensure that the battery is not connected in series, otherwise the voltage connected to the battery terminal may exceed 4.5V and burn out the board. Package List: Mini fast charging module * 1
