Hi there, My name is Raja Shahbaz Ali. I am running an R&D setup. I can assist you in developing the PCB and circuit for the desired Project. I made a circuit couple of years ago using max1491, circuit is not much stable as MAX was in trial stages. Now as you mentioned TI, Atmel and many other companies have launched the ICs and they are much stable. We will provide you: Schematics BOM PCB layout, Gerber files. Please feel free to contact. Best Regards, Shahbaz.

Dear Hiring Manager, I am a professional electrical engineer and have completed more than 150 projects for local and international clients. I've also completed 51 projects with excellent reviews here in freelancer.com. You can have a look at my profile and read the wonderful reviews about me. The quality of work is the top most priority and I never compromise upon it. Regarding your project, I can perfectly design + program the device you are intending to be developed. My deliverables usually include: 1- Complete coding (well commented and easily understandable) 2- Complete circuit design 3- Software simulation and/or hardware implementation (This needs to be discusses in chat). 4- Brief documentation on design and working of device (up to 5 pages free). 5- Free support (up to 15 days) even after the completion of the project. What I need from my client: 1- Due to high work load, I need usually more time than other freelancers take, so I need my clients to have patience, and wait unless I finish the work. I'm professional freelancer and I'm very dutiful to the works. 2- For the quality and services I provide, I suggest my client to ignore my bid if they are short of budget. If you think you have the qualities, let's have your first bestEST experience with me. Contact me to discuss a little more about the project. Regards. Faraz Ahmad

Wow! I think I may be a good candidate for this one. I have over 5 years experience designing professional electronic projects. I have done several professional project from client concept as well. I have designed similar projects before which includes designing Li-Ion and Li-Poly battery charger using CC/CV method for iPhone/iPad/other android devices. I have also designed 10 port USB charging station. I use Eagle and Altium for PCB designing. Please see my portfolio for some of my recent works. During PCB design, I always consider whether it is RF or High Speed or Power electronics PCB, because each type of them requires specific attention while laying out the traces. I could do project very quickly yet still provide professional, reliable results with FREE TECHNICAL SUPPORT after delivery. So give me a holler and we'll see what I can do. Regards, Rahman

Hi, Recently, I have done a project similar with your project. My project includes 4-cell, 45Wh Li-Po battery pack management and also includes wireless charger. I spent few months to research, optimize BOM list and finished this project. I am very familiar with Ti, Maxim, Linear chips for battery management. I researched deeply about battery protection to make battery pack safety. Here are parameters of battery which have to be protected to make battery pack safety. - Over voltage (4.2V) - Under voltage (3.2V some battery cells accept 3V or even 2.8V) - Over load - Short circuit - Cell balancing - Over temperature (often 60 deg C in discharge state, 45 deg C in charge state) A special part usually used for battery protection purpose is SCP (self-control protection) With my experience, I hope that I can receive this project from you to good result for both of us Thank you, Best regards, Khoi
