5PCS 5V 1A Micro USB 18650 Type-c Mini Lithium Battery Charging Board Charger Module Protection Dual Functions TP4056 TP4056A

TP4056A TYPE-C Module performance: Input voltage: 4.35-6 v (recommended voltage 5 V) Charge cut-off voltage: 4.2 V +/- 1% Maximum charging current output: 1000 mA Battery overcharge protection voltage: 4.28 V. Battery overcharge boost: 4.00 V. Battery discharge protection voltage: 3.0 V. Battery discharge termination voltage: 3.2 V. Battery: Overcurrent protection current 3 a Board size: about 2.5*1.65 CM Light status: no load light is off, red light is charging, green light is full.

TC4056A MICRO USB TP4056 5V 1A Features: 1. Onboard TP4056 lithium battery charging management chip. 2. The on-board microUSB head can be directly connected with most smartphone chargers as an input terminal Lithium battery charging. 3. Reserve IN+ and IN- input ports, which is convenient for users to DIY 4. Onboard charging status indicator 5. Support charging and discharging overcurrent protection 6. The chip has constant current and constant voltage, and automatically stops when full 7. Support simultaneous charging and discharging. Performance parameters: Module input voltage: DC5V Charge cut-off voltage: DC4.2V±1% Maximum output current for charging: 1A Charging method: linear charging Working environment temperature: -20℃-85℃ Instructions for use When the input terminal is connected to a voltage of 5V through micro USB or IN+, IN- input and input, and there is no wiring at the output terminal, the green light is always on, and the red light flashes quickly.    1. Charge the lithium battery    Connect the positive and negative electrodes of the lithium battery to UBAT+ and UBAT- respectively, not reverse. as the picture shows Connect to 4.8V through IN+ and IN-    Charge the 20000MAH polymer lithium battery, about to be fully charged, the voltage shows 4.19V, the charging current is 570mA It is worth noting that the charging current is preferably 0.37C of the battery capacity, which is 0.37 times the capacity. For example, a 1000mAH battery charging current of 400 is enough. If the charging speed is too large, the effect will be poor, and the battery voltage will drop more after charging! Powered by USB, the input voltage is 5V, the charging voltage is 4.19V, and the charging current is 660mA. 2. OUT terminal load The OUT port of this module can be directly connected to the load. When connected to the load, charging through the VBAT port is invalid. For the convenience of explanation, the OUT terminal is boosted by 5V through a small boost module (0.9V-5V input, 5V output) to charge the mobile phone. As shown in the figure, connect OUT+ to the positive pole of the small boost module, OUT- to the negative pole of the small boost module, and connect the mobile phone to the USB female header to charge. This module has charge and discharge overcurrent and overvoltage protection, the input terminal will not burn the chip, but the output terminal should not be connected reversely, so as not to burn the battery and the chip.
