The description states that there is temperature protection, but the wiring diagram does not show wiring for a thermister. How is the temperature protection wired?

What component should we add to have this protection and what value and how?

The BMS needs jumpers installed to configure 3S, 4S and 5S.

Can you include the temperature sensor? If not, do you know another seller that can provide it?

I thought I had it? I don't understand.

Will this work for Li-Po battery ? 3S li-po means 11.1 V.The input could be 12.0~13.0V for charging in this case or it will damage the lipo pack ?

Yes, it should work fine with LiPo batteries as well.

Can I connect just 2s?

No, the BMS needs to recognize 3 cells or it senses a fault and won't work.

Can this be setup as a 4S4P with 18650? or this can only do single parallel (1P)?

You can add as many cells in parallel as you want, BUT THEY NEED TO BE CLOSELY MATCHED BY CAPACITY AND INTERNAL RESISTANCE. This is extremely important to protect the parallel cells.

I need 3 S bms with a yellow wire to T terminal

Product Safety Information

Setup Guide

Identify the pins

Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.

Wire to your microcontroller

Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.

Install libraries

In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.

Upload example sketch

Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.

Calibrate if needed

Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
