15W 3A High-power UPS18650 Lithium Battery Charging Module

15W 3A High-power UPS18650 Lithium Battery Boost Charging Module Notes: 1. There are MOS and other components on the board, which are easily damaged by soldering iron induction electricity or static electricity. Please make sure that the soldering iron used is grounded (and the ground wire of the power strip is connected). It is best to wear anti-static gloves when operating. 2. Be careful not to install the battery upside down, otherwise the board may burn. 3. Please choose a power supply with sufficient power. Only in this way can the board work properly. 4. The board power supply should not be higher than 5V. 5. Please do not modify the board without technical confirmation. 6. It is normal for the module to heat up when working at high power, just pay attention to fanning. Product Introduction: 1. This product is suitable for power-off equipment without power outages. When there is power, use external power supply, and automatically switch to battery power supply seamlessly when there is a power outage. 2. If the USB interface is used for power supply, it is recommended to use the Type-c interface. Compared with the microUSB interface, the current that can pass is much larger, and the maximum current that can pass is 5A. 3. Suitable for routers, cameras, development boards and other devices, seamlessly switch to battery power when power is off, and keep the network connected when power is off. 4. Seamless switching between external power supply and battery dual power supply (no delay) 5. Uninterrupted power supply, automatic start when power is off, automatic charging when incoming call. 6. Output voltage 5V9V12V optional, other voltages can be customized. 7. Four practical functions: lithium battery charging, lithium battery protection, boost output, and UPS switching. 8. Two-color LED indicates charging status, the green light is always on when full, and charging stops automatically. 9. Type-C interface, large current. 10. Product size: 89 x 42mm 11. Weight: abo
