18650 Lithium Battery Boost Module Charge Discharge UPS Protection Charging Board SMD Battery Box 12V

18650 Lithium Battery Boost Module Charge Discharge UPS Protection Charging Board SMD Battery Box 12V

Module Advantages:
The module can charge and discharge at the same time. It is not easy to generate heat and safe to use. The battery panel comes with overcharge, over-discharge, and over-current protection. The battery cannot be reversely connection.

Specifications:
- Module size:
* 89 x 22 x 22.4mm(SMD Battery Box)
* 89 x 22 x 38.5mm(Normal Battery Box)
- The module mounting hole diameter is 3mm
- Input: DC5V
- Output 5V: The maximum current is 1A (the charging power supply should be greater than the current output capacity of 1A).
- Output 9V: current maximum 500mA (charging power supply should be greater than 1A current output capacity).
- Output 12V: Maximum current 350mA (charging power supply should be greater than 1A current output capacity).
- Load: The output positive and negative poles are connected to the load, the normal load is recommended to be <5W, and the transient state is <8W.

Product Size:


Attention: If it enters the protection state after a short circuit by mistake, it will not output (lithium battery overcharge protection, over-discharge protection, current limit protection, over-temperature protection, output short-circuit protection). After connecting to 5V charging, it will automatically activate and re-output.

Precautions:
There are MOS and other components on the board, which are easily damaged by induction or static electricity of your soldering iron. Please ensure that the soldering iron used is grounded (and the ground wire is connected), and it is best to wear electrostatic gloves.

Main Functions:
1) Lithium battery charging
2) Lithium battery protection (short-circuit protection, over-voltage protection, under-voltage protection)
3) Boost output 12V
4) At the same time equipped with universal Micro USB charging interface, direct DC5V input to charge lithium battery
5) Two-color LED indicates charging status, green light is always on when it is charged fully, and the charging is automatically stopped.
6) The module is equipped with high quality 18650 battery holders, namely normal and SMD types
7) UPS power failure uninterruptible power supply function.When the power supply is powered, the load is directly supplied by the power supply via the boost circuit.Once the power is turned off, the battery path is automatically activated to power the load via the boost circuit.After the power is provided again, the power is restored from the power supply and the battery is also charged.

Booster Board:
The boost section uses switches to control its operation and shutdown, and can also be directly shorted by jumper pads. (The switch needs to be equipped separately)
1. When using as a UPS, the UPS output switch should be shorted, and the output should be turned on in real time. When the power is off, the battery can be powered at any time.
2. As a mobile power supply, it can be connected to the UPS output switch interface. It is turned off when not in use. There is no static loss and it is very energy-saving.
3. If the UPS output switch interface does not need to be connected to the switch, it can also be shorted, and the output indicator light is soldered after all the tests are completed. This can reduce the current consumption of 10mA-20mA without affecting the normal output of the circuit, and save power. .
4. During the operation, it is possible that the board will enter the protection state and not output due to various reasons (mistakes, misconnections, etc.). After the problem is removed, the board charging port can be connected to the 5V charging, and the board is re-powered. The re-output can be activated.
5. The 5V charging power supply used by individual users internally uses a large capacitance output capacitor. This capacitor can continue to discharge after the power is cut off, so that the power supply voltage has a slow down process, which will cause the power supply to turn off the board. Did not switch battery power quickly. If you encounter such a situation, you can connect a 1K discharge resistor to the 5V input port.

Product Usage:
1) Can be used for single battery power supply, your battery can be replaced at any time.
2) Suitable for uninterrupted power supply solutions such as low-power DC equipment and meters. It starts automatically when the power is off, and automatically charges when the power comes in.
3) Not limited to UPS function, it can be expanded for multiple purposes. Fully charged can be used as a low-power mobile power supply, and can be used as a temporary emergency charger for lithium batteries.

Package Included:
- 1 x Set of Battery Box Charging Board
