Dual USB 18650 Lithium Battery Charging Board Mobile Power Bank Charging Module PCB Board LCD Display for Arduino DIY 5V 1A 2.1A
PCB size: 65 * 22 mm (approx.)
Power input: 5V 1A
USB output: 5V 1A / 5V 2.1A
LCD digital display panel using the steps described:
1. This product is only suitable for 3.7V 18650 battery flat.
2. Both sides of the board marked with + and - two batteries joints, pay attention: do not the battery positive and negative reversed, otherwise it will burn out the power supply board.
3. Connect the battery, the first to be charged for mobile power
· Displayed on the LCD panel IN charging for mobile power.
· LCD display on the battery is not necessarily correct, you can choose to have 100% of the charge, you can also use normal mobile power consumption in inaccurate display.
4. To the mobile power charging, take down the charging cable, mobile power for some time will automatically turn off the display and enters a dormant state.
5. Automatic sleep mode, double-click the button, lights will be lit, and then double-click will turn off lights. (And then double-click will function with SOS will start SOS, and then double-click will turn off lights)
6. Automatic sleep mode, click the button, the LCD backlight will light up blue lights and displays the percentage of battery charge current.
7. Automatic sleep mode, to charge the phone, you need a good phone with a data cable and even mobile power, click the button, move the power to charge the phone before.
8. After phone is fully charged, the power will move itself into hibernation.
Power Switch:
Click, power on; long press the power shutdown; double-click to open the LED; and then double-click to open the SOS; and then double-click, turn off the lights.
DIY Use Method:
1. the production of the battery pack (battery distinguish positive and negative)
Note: Multiple battery soldered together, be sure to add insulation sheet in the positive, without battery insulation sheet is likely to cause a short circuit.
2. use the correct enough genuine battery, soldering circuit boards.
Note: Red wire B +, black wire B-.
3. the activation circuit / charge test
5V usb charger or a computer with access to the circuit board to charge a good two or three seconds to activate, rechargeable batteries single digit displays, is 100 percent full.
Note: The new board must take good activation to normal use.
4. Discharge Test
Connect the phone, starts charging the phone. Plug and play. Display power.
Note: The mobile power is not universal, may be incompatible with some models, this is not a quality problem, a perfectionist, please carefully shot.
