Description

Charging accuracy: 1.5% Input voltage: 4.5V-5.5V Fully charged voltage: 4.2V ± 1% Current: 1A adjustable LED indicator: Red means charging and green means fully charged Input interface: micro USB Working temperature: -10° to +85° Reverse polarity: No Battery overcharge protection voltage: 4.28V Battery overcharge boost voltage: 4.00V Battery discharge protection voltage: 3.0V Battery discharge termination voltage: 3.2V Battery: Overcurrent protection current 3a Package include: 20 x TP4056 charging module Note: When the first time you access the battery, there may be no voltage output between OUT- and OUT +, at this time, get access to the 5V voltage, it will be activated The ampere meter can only be connected to the 5v input terminal of the module If you want to use Phone charger to charge, the current input should be up to 1A and more, otherwise it can not be in normal charged The charging current is preferably 37% of the battery capacity. If you charge a 1000mAH battery, 400 current is enough When the battery was get out from B + and B- , it still need to be charged then can be activated The connecting wire should not be too thick Make sure the connection point is good The input voltage is too high, such as 5.2v, and the current is less than 1000mA, which is a normal phenomenon. With protection function, the charging current is automatically subtracted to avoid burning the chip

Features

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.

These are awesome if you're into diy. The only thing they don't tell you about is that they get borline, hot. I recommend figuring out of way to do a heat sink. They are so handy. You'll find more uses, then you're originally purchased them for.
