How to Use 2S Lithium Battery Charging Protection Board - 7.4V, 5A:
This module does not perform charging operations and requires the use of another module to do that. This module is designed to protect the battery from abnormal conditions.
Steps to Follow
1. Connect the power source to the voltage buck module.
For a 3-cell battery pack, you should have a power supply of 8.4V (2x4.2). To do this, you will need a voltage buck module with a controlled current. This module needs a minimum of 9.5V on the input side in order to produce 8.4V at the output, so you should connect it to the voltage buck module.
2. Use a multimeter to adjust the output voltage.
3. To adjust the current, set the multimeter to the current mode (plug the multimeter cables into the correct ports) and then connect them to the output pads of the module and adjust the output current. Note that the output current should be less than the rated capacity of the batteries.
4.Connect the negative terminal of the first battery to the B- pad (0V) and the positive terminal to the B1 pad (4.2V). Then connect the negative terminal of the second battery to the B1 pad (4.2V) and the positive terminal to the B+ pad (8.4V).
Note: Follow this order to avoid damaging the BMS.
Then you can use P+ and P- as input and output, and connect these pads to the voltage buck module to perform the charging operation.
Next, connect the output of the Buck module to the p+ and p- pads to start charging. Remember that you should use these p+ and p- pads to use the battery.
