10Pcs USB Type C Charge Discharge Integrated Module 3.7V 4.2V for 18650 Lithium Battery with Charging Boost Power Supply Protection Module and and LED Charge Indicators 1A 5V

Product Description: This is a new type of integrated charging and discharging power board module that combines charging and boosting functions, not only overcoming the limitation of being used solely for charging or solely for discharging, but also featuring a compact and lightweight design that is easy to install and use.
Module specifications: voltage
range: 5~6V, current: 1A, interface: Type-C. When the charging current drops to 100mA after reaching the final float voltage, the charging cycle will automatically stop; when the battery voltage falls below 4.05V (which corresponds to 80% to 90% of the battery capacity), the charging cycle will resume; when the battery voltage is below 2.9V, the battery will be pre-charged with a current of 100mA.
Protection function: equipped with a protection board, it provides over-voltage protection, over-discharge protection, and over-current protection.
Over-discharge protection threshold: 2.4V
; over-current protection threshold: 4A.
Note: on first use, connect the power supply to activate the protection board; the battery must not be connected in reverse; the battery terminal voltage must not exceed the purchased voltage; the battery can only be connected in parallel, not in series, as series connection will damage the module
