YUNAWU 5A Round PCB Protection Circuit Board For 18650 Li-ion lithium 3.7V Battery Cell

Description

Connection description: P+ For Li-ion Lithium Battery Output +, P- For Li-ion Lithium Battery Output - S is the detection pin, some devices need to detect the battery voltage feet R3 is the sense resistor chip position, the resistance is required to determine the resistance of the device, so we are here to vent empty. If there is a need for bulk orders, we can paste the detection resistor on request. No Retail Package Package Includes: 1 x PCB Protection Board 1 x Plastic Base 1 x Heat Shrinkable Tube
