Features:
Module name: 1S 3.7V Li-ion Lithium Battery 18650 Charger Protection PCB Board
Maximum output current: 5A
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
"R"3 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
