Hello Barkuti,
Thanks for your reply, I learned lots of things :D
Still in this thirst for learning, I have several news questions :
1) About the TP5000/TP5100 module, a few day ago, we talked about the heat they can released during the charging process. To get 2A you advised me to combine two module in parallel set-up at 1A each, Today I ask myself a question, Is it really reliable to do this? Can they cause some weird bouncing effects due to the two ICs fighting each other?
2) About the CC/CV module and the TP5000/TP5100, does it exist an external component like an relay that can measure the voltage at the out charging terminal and when per example 4.2V is detected the component cut-off the charging module supply?
3) Another question about how to optimising TP5000/TP5100 module heat cooling. I thought of adding a Heat sink on top of the chip, however, I have a doubt about the efficiency of this one, knowing that the chip (tp4056) is 4mm * 4mm, the heat dissipation may be limited. So I was thinking of adding a larger Heat sink under the board with an adhesive thermal pad for heat conductivity, what do you think?
4) Currently, I'm designing a little 18650 charger with an tp4056 module, I would like to track the voltage and amperage during the charging process. To do this i add this little antmeter, but i'am not sure if i can wiring like this? Here is my wiring diagram, What do you think ?
Ps: I decided to put the voltmeter powering wire at the input of the tp4056 to not to disturb the charging process.
