I'm tying to power up my project, I have 4 batteries, two batteries in series and each pair in parallel to each other, (the explanation is in the attached picture), the thing is I couldn't find any proper guidance online so I'm asking you guys if you can guide me through this.
What I need is to be able to get 7.4V and 17.600 mAh, while using that circuit to charge the batteries also, the parts in the project are:
One reason for no result of guidance in the subject might be it's not a good idea.
Note that connecting 2 cells in serie, cascade, gives the Ah of only one cell.
Connecting batteries in parallell is not a good design. Divide the load and batteries into separate blocks.

Hi Railroader, what I'm trying to do here is to get higher voltage and higher capacity, sorry if I wasn't clear enough, I'm attaching a picture of what I'm trying to achieve
The thing is I still need to be able to charge the batteries with that configuration and that is why I pasted the circuit diagram
Regards,
As I said, don't connect batteries in parallell. That calls for matched, likely rather expensive, cells to take advantage of their capacity. Divide the power source - load into blocks.
Charging batteries connected in serie is also not good. It also calls for matched cells. There are sophisticated chargers charging batteris in serie but they are quite a bit complicated.
I suggest You change from those 3.7 volt LiPos to 12 volt standard battery, buck converters and a proper 12 volt charger.
