3pcs 15W 3A Battery Boost Charging Module High Power UPS 18650 Lithium Battery Boost Charging and Discharging UPS Uninterruptible Power Supply (12V)

Specification:Item Type: Battery Boost Charging ModuleMaterial: PCBSwitch Power Supply Structure: BOST BoostBattery Type: 3.7V lithium battery (4.2V fully charged)Load: Output positive and negative pole connected load, normal loadPackageList:3 x Battery Boost Charging Module

• Equipped with dual color LED to indicate the charging state, the green light is always on when it is fully charged, and the charging stops automatically.
• The module is equipped with two 18650 battery sockets, a universal Micro USB charging port, and direct DC5V input to charge the lithium battery.
• 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)
• UPS function: When the power supply is powered, the power supply directly supplies power to the load through the boost circuit, and at the same time charges the lithium battery. 1 the power is cut off, the battery path is automatically started to supply power to the load via the boost circuit.
• The 5V charging power supply used by individual users uses an output capacitor with a larger capacitance value. This capacitor can continue to discharge after the power supply is powered off, so that the power supply voltage has a slow down process, which will cause the board to not switch battery power supply quickly after the power supply is turned off. If you encounter such a situation, you can connect a discharge resistor of about 1K at the 5V input port.
