20pcs 18650 Lithium Battery Charging Board TP4056 Mini USB Charging Board 5V 1A with Protection Dual Functions TP4056 Charge Module
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•TP4056 is a complete single-cell lithium-ion battery with a constant current/constant voltage linear charger, is suitable for USB power supply and adapter power supply.
•TP4056 charging module charging voltage is fixed at 4.2V, and the charging current can be set externally through a resistor. When the charging current reaches the final float voltage and drops to 1/10 of the set value, the TP4056 will automatically terminate the charging cycle.
•When the input voltage (AC adapter or USB power supply) is removed, the TP4056 automatically enters a low current state, reducing the battery leakage current to less than 2uA.TP4056 can also be placed in shutdown mode when there is power supply, reducing the power supply current to 55uA.
•18650 lithium battery charger board input voltage is 5V, battery over-discharge protection voltage is 2.5V, B + positive then the lithium battery, B- then negative lithium batteries.OUT + and OUT- connected to the load, such as positive and negative electrodes connected mobile booster plate or other load.
•Battery charging board connect the battery to the B + B-, inserted into the USB female mobile phone charger, the red light is being charged, the green light to full.
