     EGoksy suggest to me on youtube to try use the CE pin of the TP4056

     In order to simply more the schematics and lower price for the components i make few test with CE pin of the TP4056.
     From data sheet:
     CE(Pin8): Chip Enable Input. A high input will put the device in the normal operating mode. Pulling the CE pin to low level will put the YP4056 into disable mode. The CE pin can be driven by TTL or CMOS logic level.
      
     

     So by putting an pull down resistor of 10k from GND to Pin8 the cip go in disable mode and dont charge anymore.
     I use the digital pin for the IRFU5305 P channel Mosfet to pull up de Pin8 and like that i remove from the schematics the P-Channel Mosfet.

     Now u can control the charge without P-Channel Mosfet

     To do this u need to unsold the Pin8 from the +5V rail

Hope this will help u too.

Best regards

Check if you have the right TP4056 chip Wink
All mine are counterfeits and CE doesn't work Sad

hi constantin,

how do you read out the „fully charged“ status via led. it is either red or blue, sometimes blinking... how do you identify what status it is?
