Cannot be reversed. Reverse connection of lithium batteries (also called reverse connection batteries) refers to the reverse connection of the positive and negative poles of the lithium battery in the circuit, resulting in poor connection of the battery. This may cause circuit and battery failure. short circuits, heat and even explosion consequences, therefore reverse connection operation is strongly discouraged.
The differences between direct wiring of lithium batteries and plug connection are as follows. The difference in basic functions: When charging with a data cable, data can be transmitted while charging, but data cannot be transmitted when charging with a power plug.
1. Appearance differences: The data cable is thicker (because there are four wires), while the charging cable of the socketThe power supply is thinner (because there are only two wires).
