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, 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.
