1. First, buy a new battery.
2. Four batteries need four or five connecting wires, usually four connecting wires.
3. Tighten the battery cable.
4. The air switch can prevent short circuit and combustion of the electric vehicle.
5. Electric vehicle wiring harness.
6. Battery connection. The battery is divided into positive electrode and negative electrode. The red end is the positive electrode and the blue end is the negative electrode. Connect the red terminal to the positive electrode (red terminal) of one battery and the black terminal to the negative electrode (blue terminal) of another battery with a connecting wire, and then connect each battery in this way. Finally, the starting point and the ending point are the positive electrode and the negative electrode respectively (that is, the blue end and the red end of the battery).
The method of unpowered external battery for electric vehicle;
(1) Type of electric bicycle. An elbow wire and a battery socket, with red wire connected to red wire and black wire connected to black wire.
(2) Electric motorcycle style. The red line of the two elbow lines is connected with the red line, and the black line is connected with the black line.
Good arrangement of battery connection can reduce fault points, prevent lines from mutual wear, reduce fire causes and improve the service life of batteries. Customers will have less trouble using your batteries, and our business will be better.
