Product details of DC Mini UPS Circuit Module 9V/12V 1A Charging Discharge Module for 18650 Lithium Battery UPS Voltage Converter Uninterruptible Power Supply Board

DC UPS Uninterrupted Charging Module 5V-12V to 9V 12V 1A 18650 Lithium Battery Boost Step Up Power Supply Voltage Control Board

Product description:

• Input voltage: DC 5V-12V (this voltage is the voltage when charging the battery)
• Output voltage: DC 9V or DC 12V can be selected (default is 9V, you can also change the jumper to set to 12V, and the output voltage is the voltage when only battery power is used, if there is a charging input, the output will be equal to the input)
• Output power: MAX 12W
• Board size: 50*20*6mm

• BAT connection is the last step before connecting the battery. This is very important. Battery 3.7V lithium battery or polymer battery, battery capacity: 1-3AH (MAX 5AH)

Application description of accessories for charging indicator:
