I need PCB design for Solar panel circuit (21V) to charge Litio battery (3.7V -4.2V).
-PCB 2 layers in KiCAD
-I'll provide PCB shape in KiCAD file
-I'll provide actual PCB circuit in KiCAD file
-PCB dimensions less than 90x90mm (has enough space)
For now I have one circuit done in KiCAD but there is something that not working properly. Now 4.2V is provided as output of solar panel circuit but when we connect the battery, doesn't reach more than the initial battery voltage.
Project circuit will be validated making the PCB through JLCPCB.
If the solutión is easy requiring only some changes using the actually board I have, validation will be done very fast and extra € bonus will be provided.
No extra capacitors as solution...I have already tested :)

No payment before validation!!! If you are really good, I can hire you for other projects.
If the PCB design doesn't work because your lack of experience, the project will be cancelled and no more projects with you.

Hello, If I succeeded in Eagle to Altium conversion, is it acceptable alternative? JLCPCB: Project delivery time impact with delivery to Spain (?). Please show me the schematic before starting. Regards, Ashot
