DC 5V-12V to 12V Step Up Charging Module

Description:DC 5V-12V to 12V Step Up Charging Module for 18650 Lithium Battery UPS Voltage Converter. It is a UPS uninterruptible power control board.Features:

• Support charging and discharging at the same time
• Big current
• Small format
• High efficiency
• Support short circuit protection

3.Parameters:

• Product Name: UPS Voltage Converter Module
• Working voltage: DC 5.0V-12.0V
• Output voltage: DC 12.0V
• Output power: 12W
• Support Battery (No contain!): 3.7V Lithium or polymer battery 15Ah(Max)
• Temperature range: -40 ~ 85
• Working humidity range: 0%-95% RH
• Size:50*20*6.3mm

4.Using Steps:

1. Connect right input voltage at input terminal.
2. Check output voltage by voltmeter and ammeter.
3. Connect battery to B+ and B-.

Note:

1. Its max output current is 1A and can’t keep output 1A.
2. The positive and negative poles of the input power supply cannot be reversed. Otherwise, the module will be damaged.
3. Users can install a common anode Red-Blue LED by yourself as charging indicators. blue light indicates whether there is a load on output. hold Red is charging. there is no battery when flashing Red. Red OFF when charged.
4. Due to the large current, it is recommended to use a thicker wire. wire cross-section greater than 1.5 square millimeters.
5. Please read use manual and description before use.
6. JP1 is to output voltage (short circuit is 12V output, disconnected is 9V output).

7. JP2 is to charge current for the battery (short circuit is about 1A, disconnection is about 0.5A).

Application:
