Módulo de carregamento boost de bateria de lítio UPS18650 de alta potência 15W 3A, 5V, 9V, 12V

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 5V/9V/12V 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: about 37g

Function description:
1. UPS function: When the power supply is powered, the power supply directly supplies power to the load through the boost circuit, and charges the lithium battery at the same time. Once the power supply is off, the battery path is automatically started to supply power to the load through the boost circuit.
2. Boost circuit: peak power up to 20W, rated power up to 15W, BOST boost circuit, built-in 12A high current MOS, efficiency up to 96%, module static power consumption 25mA, optional 5V/9V/12V output.
(Load normal recommendation <15W. Output 5V: current 3A, output 9V: current 1.6A, output 12V: current 1.2A)
3. Lithium battery protection overcharge, over discharge, over temperature, over current protection (if short-circuited by mistake, it will enter the protection state and no output, and it will automatically activate and restore output when connected to 5V charging)
