Are the two wires at the bottom of the 16.8V lithium battery protection board divided into positive

Points. The lithium battery protection board has 5 wires, 2 thick wires at the bottom, red is the positive pole of the power supply, black is the negative pole of the power supply, and the other three are power detection wires. signal, which are used to judge whether the battery voltage is too low or too high, and plays a role in battery protection. Here is the wiring method of 16.8V lithium battery protection board: Buy a new set of batteries first. Four batteries require four or five connecting wires, usually four connecting wires. Install the battery connection wire screws and turn on the air. It can prevent the electric vehicle from short circuiting and burning the car. Connect the red end of one jumper wire to the positive electrode of the battery (the red end) and the black end to the negative electrode of the other battery. (the blue end), then each battery is coconnected like this. The starting point and the ending point are the positive and negative poles (that is, the blue end and the red end of the battery) respectively, and the installation is. completed.
