DC 12V 3A 24W 36W 3S Lithium Battery Pack UPS Module Charging Discharging Automatic Switching Uninterruptible Power Supply Board

Input voltage: DC12V

Output voltage: DC12V (between 11V and 13V)

Output power: 36W (MAX)

Battery charging current: 0.5A (MAX)

The specific input current depends on the load carried, and the working current of the load plus the charging current (0.5A) is the current of the input power supply

Equipped with battery pack charging, discharging and discharging protection function

Automatic switching of power supply from battery

 

Matters needing attention:

Please connect the battery as the last step, this is very important!!! 3S lithium ion battery or polymer battery or 18650 battery pack

Default battery pack: It can be connected to 2 wires (positive and negative) or 4 wires, and the resistors R16, R17, and R18 need to be removed

Please connect the battery as the last step, and use at least 20AWG wire for soldering input and output. The wire length should not exceed 10CM, and the connecting wire should be as thick and short as possible.

The control board generates heat during operation, so it should be installed at a certain distance from the battery!

Indicator light: Customers need to configure a 3mm common anode red green light-emitting diode themselves; Charging light on, red light on, fully charged green light on
