Good day. I'm having serious issue on my project (Battery pack)12v with my charger(12v 5A). I'm building the park with 18650 cells. Due to inbuilt charger. But the solution I found online is not well satisfactory which are diode and P Channel MOSFET. It reduces the volts too much and I need a better solution or if anyone can please teach me how to do P Channel MOSFET connection for best result.

Sorry but pictures don't help understand what you are trying to do.
Please post a schematic.

So you can't tolerate the half volt drop of a Schottky diode?
