No. The battery model of the 3-wire Bluetooth headset is different from the battery model of the 2-wire Bluetooth headset and cannot be replaced. The lithium polymer battery of Bluetooth headset battery mainly refers to the lithium ion polymer battery. According to the different electrolytic materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries or plastic lithium-ion batteries. ionic batteries.
The difference between two wires and three wires on the battery
1. First, peel off the three wires from the lithium battery to expose the three wires. Find the “ground wire” and. take one. The green wire is the "ground wire".
2. Next, peel back the other two wires to expose the two wire cores, and remove the "ground wire" from all three wires.
3. Finally, connect the corresponding live and neutral wires and connectthem with the same color. Simply seal the interface with electrical tape.
Can the three-wire 7.4V battery in the theater be replaced with a two-wire battery?
The difference is: The three-wire battery can detect the battery temperature, but the two-wire battery cannot detect the temperature.
The red line on the battery is the positive electrode, the black line is the negative electrode, and the other colored lines are the center electrode of the battery. These three lines are connected to the motherboard of the product. . The middle electrode allows the product motherboard to monitor the voltage of the lithium battery.
The other colored wires are the NTC and the thermistor of the protection board. The thermistor is used for the motherboard to detect the temperature of the lithium battery or to distinguish the battery type.
