Develop a charging controller circuit for Li-ion Lithium rechargeable 14.8V battery pack using solar panel. Please follow Li-ion charging guidelines and recommendations to make the batteries last longest possible time accounting for the limitations of solar power. [login to view URL] [login to view URL] These are required components: 4 X rechargeable batteries either 1200mAh or 2200mAh 3.7V [login to view URL] [login to view URL] 1 X battery enclosure to produce roughly 14.8V However the system also works fine even if voltage drops down to 6-7V. [login to view URL] 1 X solar panel to charge the batteries. [login to view URL] Circuit should have digital output with the battery pack voltage reading. The resulting PCB should be small (under 6x4cm) and relatively economical to produce. We need Gerber files, Eagle source files and BOM file with links to all required components from Mouser or Digikey.

Hi, I am an Electrical Engineer and expert in PCB designing and manufacturing. I have designed a lot of PCB that includes Analogue, Digital and Embedded circuits as well. I have worked on wide range of micro-controllers as well that includes PIC, ARM, Arduino, ATMEL, STM32, Rasberry Pi etc. I have designed more than 100 PCB. Now-a-days as the world is moving from larger size objects to smaller one, so its a good practice to reduce the size of PCB as smaller as possible.

Hi! I can develop the system(PCB) that you need in 3 days. What i will give in PCB? An input on PCB that connects to the solar panel for charging the battery. A diode connected to it to prevent the polarity reverse damage. 4x Lithim battery pack in which you can place 4 batteries. At Output i will provide four voltages +5v,+6v,+8v,+9v Using 78xx series regulators. A button that will switch off and on the output. So you can switch off the circuit in day when no output(voltage: Load is not driven) is needed. Proper input and output connectors will be mounted on PCB. I will give link off each component that is to be mounted on PCB. I will also help you in placing cheap PCB order. Message me if you want to discuss more about the project. About Me I am a professional PCB and Circuit Designer. I designed many circuits and their PCB's. I also do programming of microcontrollers and their interfacing with different electronics components. I have experience in Pic,8051, Arduino, Atmel etc. For PCB design i use Eagle Pcb Design software by Cadsoft. I am Running a Website Under the name www . microcontroller-project . com You can see my work on it. Their are lot of Projects on it using different microcontrollers. King Regards Usman Ali Butt
