10pcs 18650 Lithium Battery Charging Module TP4056 1A with Battery Protection BMS and 2A 5V Charge Discharge Module Boost Power PCB Board for Mobile Protection Review

TP4056 Charging Module - Inputs with MICRO USB female, can be directly input to do with the phone charger rechargeable lithium battery, And still retains the input voltage wiring pads, can be very convenient DIY. Charging cut-off voltage: 4.2V ± 1%; Maximum charge current: 1000mA. TP4056 Charging Module - Input voltage: 5V; Battery over-discharge protection voltage: 2.5V; Batteryovercurrent protection current: 3A; Connect the battery to the B+ B-, inserted into the USB female mobilephone charger, the red light is being charged, the green light to full. The charge should disconnect the load OUT terminal on the positive and negative can not be wrong, please according to specifications, otherwise it will damage directly. 2A 5V Charge Discharge Integrated Module - MCU users, if you accept a small load KEY can be connected to the microcontroller about 20s to provide a low level allows the module to continue working. Trigger mode: low level trigger (ground) . 4 in 1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection. 2A 5V Charge Discharge Integrated Module - In discharge mode (The charging mode KEY function is invalid), trigger the KEY port once to open the output; continuously trigger the KEY port twice to close the output. The first time the load is connected, the output is automatically turned on. If the load is less than 50MA, the output will be automatically turned off after 30 seconds; if the load is greater than 50MA, the output will be automatically turned on. Allow discharge while charging. (Note: At this time output voltage 4.7 / 5V).
